9-12 ppt of Acids and Bases. Students will learn that the chemical difference between acids and bases is that acids produce hydrogen ions and bases accept hydrogen ions. A base is a substance that neutralises acids. When bases are added to water, they split to form hydroxide ions, written as OH-. We call a base that has been added to water an alkaline solution. Students will also learn that an acid–base reaction is a chemical reaction that occurs between an acid and a base. It can be used to determine pH via titration.
Some of the uses of Acids are:
Carbonic acid (H 2 CO 3 ) is present in the aerated cool drinks we drink. Sulphuric Acid (H 2 SO 4 ) is used in car batteries. Sulphuric Acid (H 2 SO 4 ) is also used to manufacture Paints, dyes, synthetic fibres etc. Nitric acids (HNO 3 ) is used in manufacturing of fertilizers.
Some of the uses of Bases are: It is used to neutralize the acidity in soils.
It is an ingredient in whitewash and mortar. It is a component of the Bordeaux mixture used for protecting agricultural crops from pests. It is used in the preparation of dry mixes for painting and decorating.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

Acids and bases ppt.ppt
1. Acids & Bases
They are everywhere..
In your food
In your house
EVEN IN YOU!!!!!
2. What is an acid?
An acid is a solution that has an
excess of H+ ions. It comes from the
Latin word acidus that means "sharp"
or "sour".
The more H + ions, the more acidic
the solution.
3. Properties of an Acid
Tastes Sour
Conduct Electricity
Corrosive, which means
they break down certain
substances. Many acids can
corrode fabric, skin,and
paper
Some acids react strongly
with metals

4. Uses of Acids
Acetic Acid = Vinegar
Citric Acid = lemons,
limes, & oranges. It is in
many sour candies such
as lemonhead & sour
patch.
Ascorbic acid = Vitamin
C which your body needs
to function.
Sulfuric acid is used in
the production of
fertilizers, steel, paints,
and plastics.
Car batteries
5. What is a base?
A base is a solution that
has an excess of OH-
ions.
Another word for base
is alkali.
Bases are
substances that can
accept hydrogen ions
6. Properties of a Base
Feel Slippery
Taste Bitter
Corrosive
Can conduct electricity.
(Think alkaline
batteries.)
Do not react with metals.

7. Uses of Bases
Bases give soaps,
ammonia, and many
other cleaning products
some of their useful
properties.
The OH- ions interact
strongly with certain
substances, such as dirt
and grease.
Chalk and oven cleaner
are examples of familiar
products that contain
bases.
Your blood is a basic
solution.
8. pH Scale
pH is a measure of how acidic or
basic a solution is.
• The pH scale ranges from 0 to 14.
Acidic solutions have pH values
below 7
A solution with a pH of 0 is very
acidic.
A solution with a pH of 7 is neutral.
• Pure water has a pH of 7.
• Basic solutions have pH values
above 7.
9. pH Scale
• A change of 1 pH unit represents a tenfold
change in the acidity of the solution.
• For example, if one solution has a pH of 1 and
a second solution has a pH of 2, the first
solution is not twice as acidic as the second—
it is ten times more acidic.
10. Acid – Base Reactions
A reaction between an
acid and a base is
called neutralization.
An acid-base mixture
is not as acidic or
basic as the individual
starting solutions.
11. Acid – Base reactions
Each salt listed in this
table can be formed by
the reaction between an
acid and a base.
