Quantitative Analysis: Volumetric Analysis (Any four)

1.    Iodometry titration – Determination of strength of CuSOsolution 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)ionby 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

      (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).
