Quantitative Analysis: Volumetric Analysis (Any four)
1. Iodometry titration – Determination of strength of CuSO4 solution using sodium thiosulphate.
2. Redox titrations –

(b) Determination of strength of acid from the mixture of strong acid and weak acid
(e.g. H2SO4and H3PO4).
(c) Determination of strength of sodium carbonate and NaOH in the mixture of washing soda
and NaOH with HCl using phenolphthalein and methyl red indicator.
4. Complexometric titration – Estimation of hardness of water by EDTA (Temporary and permanent).
Organic Chemistry
Qualitative Analysis
