Laboratory Course

Calibration of fractional weights, pipettes and burettes, preparation of standard solutions, dilution – 0.1 M to 0.001 M solutions, buffer solutions.

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.

Detection of elements (Nitrogen, Sulphur and Halogens) and functional groups (phenols, alcohols, carboxylic acid, carbonyl, ester, carbohydrate, amine, amide and nitro) in simple organic compounds and determination of their melting/boiling points.

1. first order kinetics- hydrolysis of methyl acetate catalyzed by HCl.

2. Second order kinetics- Saponification of ethyl acetate.

3. Determination of freezing point depression constant of camphor using Rast method.
