This document discusses acids, bases, and salts. It defines acids as substances that release hydrogen ions (H+) in water, and bases as substances that release hydroxide ions (OH-). Strong acids and bases fully dissociate in water, while weak ones only partially dissociate. Acids react with metals and bases to produce salts and either water or hydrogen gas. The pH scale is used to measure acidity, with acidic solutions having a pH below 7 and basic solutions above 7. Common examples of acids, bases, and salts are also provided.

We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

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.
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.

2. ACID
❏ Latin term ‘accre’ means sour
❏ Used by Robert Boyle in 17th century
❏ It’s a substance which release hydrogen ions (H+) when dissolved in water.
❏ (H+) does not exist alone, it combines with water molecule (H2O) and forms
(H3O+) (Hydronium ion)

➢ Neutralization is the process in which acid react with base each other to
produce salt and water.
➢ Salt is obtained when hydrogen of acids is replaced by the metal.
Eg:- HCl NaCl, H2SO4 Na2SO4
Common Salt:- NaCl is Obtained from sea
28. Fact Checking
➔ Metallic Oxides are Basic Oxides:
Because metallic oxides react with acids to give salt and water, similar to the
reaction of a base with an acid
➔ Non-metallic oxides are Acidic oxides:
Because non-metallic oxides react with bases to give salt and water, similar
to the reaction of an acid with base.
29. Role of water in dissociation
➔ Most of the acids and bases have no dissociation (furnishing H+ and OH-)
without water.
➔ Dissociation process is highly exothermic.
30. Self dissociation of water
➔ Dissociation of water itself is extremely small and only about 2 out of every billion water
molecules are dissociated in 25oC.
➔ H2O ⇌ H+ +OH-
➔ H+= OH- = 1.0 x 10-7
➔ Pure water or ionic product of water is H+= OH- It’s symbolized as Kw (Ionic Constant
product of water). So we conclude that:
Kw = [H+] [OH-] ie: Kw = (1.0 x 10-7) x (1.0 x 10-7)
Kw = 1.0 x 10-14
34. pH and its importance
➔ pH means the power of hydrogen
➔ It was denoted by Danish biochemist Soren Sorensen in 1909.
pH= log 1/[H+]
➔ Acid rain is 5.6 pH
40. Common acids and bases
Common acids pH Value Common Bases pH Value
HCl 0 Blood Plasma 7.4
Stomach acid 1 Egg white 8
Lemon Juice 2 Sea water 8
Vinegar 3 Baking soda 9
Oranges 3.5 Antacids 10
Soda, Grapes 4 Ammonia water 11
Sour Milk 4.5 Lime water 12
Fresh Milk 5 Drain cleaner 13
Human Saliva 6-8 Caustic soda 14
Pure water 7
42. Use of pH in everyday life
➔ pH in humans and animals: Biochemical reactions in our body are narrow are
in narrow pH range of 7.0 -7.8. Even small change in it disturbs this process.
➔ Acid rain: if rain water falls below pH 5.6 it’s called acid rain.
➔ pH in plants: plants have a healthy growth when a specific pH range is
maintained.
➔ In digestive system: Our stomach produce hydrochloric acid which helps
digestion of food.
➔ Self defence of animals and plants: Bee sting causes severe pain and burning
sensation.it’s due to methanoic acid. Use of mild base can prevent it.
43. Use of pH in everyday life
➔ Self defence of animals and plants: Nettle plant have fine stinging hair which
inject methanoic acid.
➔ Tooth decay: tooth enamel is made of calcium phosphate which hardest
substance in our body. If we didn’t wash our mouth properly after every meal,
the food particles and sugar remaining in mouth produces acids with the help
of bacterias in our mouth. If its pH goes below 5.5 it cause to corrode the
tooth enamel and tooth decay.
