Quantitative Analysis: Volumetric Analysis (Any four)   

1. Iodometry titration – Determination of strength of CuSO₄ solution using sodium thiosulphate.
2. Redox titrations –                                                                                       (a) Determination of strength of ferrous sulphate solution using K2Cr2O7.(b) Estimation of ferrous (Fe+2 ) and ferric (Fe+3 ) by dichromate method.

3. Acid-base titration –                                                                                   (a) Determination of acetic acid in commercial vinegar using NaOH.       (b) Determination of strength of acid from the mixture of strong acid and weak acid ( eg. H₂SO₄ and H₃PO₄ ).                                                     (c) Determination of strength of sodium carbonate in the mixture of  washing soda and NaOH with HCl using phenophthalein and methyl red indicator.

4. Complexometric titration – Estimation of hardness of water by EDTA.
