What measurements are needed in the titration of a weak acid? explain in detail the technique or procedure for adding the titrant to accurately determine the concentration and pka of a weak acid.

An acid-base titration is a quantitative analysis of acids and bases; through this process, an acid or base of known concentration neutralizes an acid or base of unknown concentration.The titration progress can be monitored by visual indicators, pH electrodes, or both.The reaction's equivalence point is the point at which the titrant has exactly neutralized the acid or base in the unknown analyte; if you know the volume and concentration of the titrant at the equivalence point, you can calculate the concentration of a base or acid in the unknown solution.
