The Analyte and reference reagents
TITRANT
It was employed in analytical chemistry to identify several species, including metal ions, acids, bases, oxidants, and reductants.
TITRATION
The end point of the titration. denotes a finished reaction
EQUIVALENCY
This is a quantitative analysis based on the measurement of the volume of a solution with a known concentration of a reagent required for reaction and a given amount of an unknown substance being determined
TITRIMETRIC METHOD OF ANALYSIS
It is known concentration of a reagent
TITRANT
It is the unknown substance
ANALYTE
It includes a group of analytical methods that are based on determining the quantity of a reagent of known concentration that is required to react completely with the analyte. The reagent may be a standard solution of a chemical or an electric current of known magnitude.
TITRIMETRY
The volume of a standard reagent is the measured quantity.
VOLUMETRIC TITRIMETRY
The charge in coulombs required to complete a reaction with the analyte is the measured quantity.
COULOMETRIC TITRIMETRY
is a theoretical point reached when the amount of added titrant is chemically equivalent to the amount of analyte in the sample.
EQUIVALENCE POINT
These are often added to the analyte solution to produce an observable physical change (the end point) at or near the equivalence point.
INDICATORS
This is a highly purified compound that serves as a reference material in volumetric and mass titrimetric methods.
PRIMARY STANDARD
This is a reagent of known concentration that is used to carry out a titrimetric analysis.
STANDARD SOLUTION
Extraneous substances should be non-existent in the solution or, at the very least, impurities are considered negligible. This is crucial for accuracy and precision.
HIGH LEVEL OF PURITY
Following the idea of purity, if the solute reacts with air or water, it will no longer be pure, limiting the chance of achieving the desired results.
NON REACTIVE WITH AIR OR WATER
