Course Objectives :

The course aims to acquaint the students with various safety measures including handling of chemicals, safe disposal of chemical wastes etc., to make students understand the concept of separation of mixtures containing metal ions, insolubles and interfering radicals and to make students learn about the quantitative estimation of different ions volumetrically.

Unit I: 

Laboratory Safety Measures                                                                                 

Safe working procedure and protective environment, protective apparel, emergency procedure and first aid, safe storage and use of hazardous chemicals. Procedure for working with gases above or below atmospheric pressure, safe storage and disposal of waste chemicals, recovery, recycling and reuse of laboratory chemicals, neutralization of strong acids and strong bases, procedure for laboratory disposal of explosives.

 

Qualitative Mixture Analysis                                                                                                                        

Analysis of mixture for eight radicals (cations and anions) including

  1. Less common metal ions – Mo, W, Ti, Zr, Th, V, U (two metal ions in cationic/anionic forms).
  2. Insolubles – oxides, sulphates and halides.
  3. Interfering- oxalate, phosphate, borate, fluoride.

 

Quantitative Analysis: Volumetric Analysis (any three)

  1. Determination of Chloride ion in water by Mohr’s method or by use of adsorption indicator.
  2. Determination of Nickel using Eriochrome Black T as an indicator (Back titration).
  3. Determination of percentage purity of boric acid.
  4. Determination of Nitrite in a given sample.
