Question

defined the principle of volumetric analysis.​

Answer 1

Explanation:

The basic principle of Volumetric analysis: The solution which we want to analyze contains a chemical of unknown amount then the reagent reacts with that chemical of unknown amount in the presence of an indicator to show the end-point. End-point shows that the reaction is complete.

Answer 2

Answer:

In volumetric analysis the weight of a reagent necessary to complete a chemical reaction is ascertained by determining the volume of a solution containing a known concentration of the reagent required to react stoichiometrically with the element. From this volume the percentage of the element can be calculated.
