Acid/Base Titration
Importance of Acid-base Titrations
Acid-base titrations are used for the following purposes:
- To standardize a solution of an acid or a base (standardization)
- To determine the molar mass of an acid or base.
- To establish the molar ratio of acid to base in a neutralization reaction.
- To determine the percentage purity or impurity of acid or base.
- To estimate the percentage of water of crystallization in an acid or base.
- To determine the solubility of a base.
1. Standardisation of a Solution
A solution of an acid of unknown concentration can be standardized, i.e. its concentration determined, by the use of a standard solution of a base, vice versa. A balance equation of reaction is required, in order to obtain the mole ratio.
Examples:
1. A is a solution of tetraoxosulphate {vi} acid. B is a solution containing 0.0500 mole of anhydrous Na2CO3 per dm3.
