Definition of various terms used in Volumetric analysis
Volumetric Analysis:
Volumetric Analysis is to determine the volume of a solution of know concentration require to react quantitatively with a solution of substance to be analyzed.
Volumetric analysis is also called as titrimetiric analysis.
Titrate: Substance to be analyzed or to be determined
Titrant: Reagent of know concentration
Titration: The process of determining the volume
Equivalence point: The point at which complete chemical reaction takes place and equivalent quantity of reagent is used
End Point: The point at which the indicator changes its color
Indicator: Auxiliary agents used to determine the end point of titration
Concentration: A defined quantity of substance in a defined volume of solution
Normality: The number of gram equivalents of solute present in one liter of solution and represented by “N”
Molarity: The number of moles of solute presents in one liter of solution and represented by “M”
Molarity: The number of moles of solute per 1000gm of solvent and represented by “m”
Importance of Volumetric analysis:
- High precision is obtained
- Simple apparatus is required
- Easy process and fast result
- Different methods for different types of substance
