This document defines key terminology used in titration analysis. It explains that a titration determines the concentration of an unknown solution by measuring the volume of a known standard solution required to reach the endpoint of a chemical reaction. The standard solution is called the titrant. The unknown solution is the titrand or analyte. An indicator is used to signal when the endpoint is reached. The equivalence point occurs when the moles of titrant equal the moles of analyte, while the endpoint marks the end of the reaction. Primary standards are pure and used to make secondary standards of known concentration for titrations.
Volumetric analysis is a quantitative analytical method which is used widely. As the name suggests, this method involves measurement of the volume of a solution whose concentration is known and applied to determine the concentration of the analyte.
Titrimetric analysis is a method of analysis in which a solution of the substance being determined is treated with a solution of a suitable reagent of exactly known concentration. The reagent is added to the substance until the amount added is equivalent to the amount of substance to be determined.

What is Gravimetric analysis, stepes invloved in gravimetry, Filteration medium in gravimetry, gravimetric factor, application, organic and inorganic prepecating agents
It is an electrochemical method of analysis used for the determination or measurement of the electrical conductance of an electrolyte solution by means of a conductometer.
Electric conductivity of an electrolyte solution depends on :
Type of ions (cations, anions, singly or doubly charged
Concentration of ions
Temperature
Mobility of ions
The main principle involved in this method is that the movement of the ions creates the electrical conductivity. The movement of the ions is mainly depended on the concentration of the ions.
The electric conductance in accordance with ohms law which states that the strength of current (i) passing through conductor is directly proportional to potential difference & inversely to resistance.

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.

BASIC TERMINOLOGY IN
TITRATION
3. BASIC TERMINOLOGY IN
TITRATION
TITRATION:
A titration is a technique where a solution of
known concentration is used to determine the
concentration of an unknown solution. Typically,
the titrant (the known solution) is added from
a burette to a known quantity of the
analyte/titrate (the unknown solution) until the
reaction is complete. Knowing the volume of
titrant added allows the determination of the
concentration of the unknown. Often, an indicator
is used to usually signal the end of the reaction,
the endpoint
4. BASIC TERMINOLOGY IN
TITRATION
TITRANT:
Titrant is a substance added from the burette. Titrant
used and the reaction principle that proceeds usually
defines name of the titration - like acid-base (or
alkalimetric) titration if we use strong acid (or strong
base) as a titrant, or redox when the reaction that
proceeds is of a redox type.
TITRATE/ ANALYTE
Titrate is (analytical chemistry) to ascertain the
amount of a constituent in a solution (or other mixture)
by measuring the volume of a known concentration
(the "standard solution") needed to complete a
reaction. Analyte is a substance whose chemical
constituents are being identified and measured.
5. BASIC TERMINOLOGY IN
TITRATION
INDICATOR:
Indicator is a substance that changes color in
response to a chemical change. An acid-base
indicator (e.g., phenolphthalein) changes color
depending on the pH. Redox indicators are also
used. A drop of indicator solution is added to the
titration at the beginning; the endpoint has been
reached when the color changes.
6. BASIC TERMINOLOGY IN
TITRATION
EQUIVALENCE POINT:
The equivalence point is the exact point in a
titration when moles of one titrant equal the moles
of the substance being titrated.
ENDPOINT:
The endpoint is the point where the system
changes when the moles of the reacting titrant
exceed the moles of the substance being titrated.
7. BASIC TERMINOLOGY IN
TITRATION
Difference between Equivalence Point and
End Point?
The equivalence point in a titration is the point at
which the added titrant is chemically equivalent
completely to the analyte in the sample. End point
is the point where the indicator changes its color.
Equivalence point comes before the end point.
8. BASIC TERMINOLOGY IN
TITRATION
STANDARDIZATION:
Standardization is the process of determining
the exact concentration (molarity) of a solution.
Basically standardardization is carried to know
the strength of the secondary standard prepared
for carring out the assay. It is done to ensure the
strength of secondary standard prepared. The
strength calculated after standardization is used
to calculate the content or percentage purity.
9. BASIC TERMINOLOGY IN
TITRATION
PRIMARY STANDARD:
A primary standard is a reagent which is very pure,
representative of the number of moles the substance contains
and easily weighed.
Primary standards are typically used in titration to determine an
unknown concentration and in other analytical
chemistry techniques. Primary standards are often used to make
standard solutions.
Properties of Primary Standards
A good primary standard meets the following criteria:
high level of purity
low reactivity (high stability)
high equivalent weight (to reduce error from mass
measurements)
not hygroscopic (to reduce changes in mass in humid versus dry
environments)
non-toxic
inexpensive and readily available
10. BASIC TERMINOLOGY IN
TITRATION
SECONDARY STANDARD:
A related term is "secondary standard". A
secondary standard is a chemical that has been
standardized against a primary standard for use
in a specific analysis. Secondary standards are
commonly used to calibrate analytical methods
11. BASIC TERMINOLOGY IN
TITRATION
DRUG:
Drug is a Natural or synthetic substance which
(when taken into a living body) affects its
functioning or structure, and is used in the
diagnosis, mitigation, treatment, or prevention of
a disease or relief of discomfort.
ASSAY :
An assay is a test of a substance to find out what
chemicals it contains. It is usually carried out to
find out how pure a substance is.

16. BASIC TERMINOLOGY IN
TITRATION
Percent (%) Solution
The concentration is expressed in terms of per cent
(parts per hundred) also. Per cent Composition of a
solution can be expressed as:
1. Per cent W/W = Weight of solute/ Weight of solution X100
2. Per cent V/V =Volume of solute/ Volume of solution X 100
3. Per cent W/V= Weight of solute/ Volume of solution X100

Parts Per Million
Parts per million is frequently employed
to express the concentration of very dilute
solutions and is express as PPM
