PRACTICAL PART

30 (Periods)

Practicals should be conducted along side the concepts taught in theory classes.

(List of Experiments)

1. Preparation of :

a) a true solution of common salt, sugar and alum

b) a suspension of soil, chalk powder and fine sand in water

between these on the basis of

• transparency

• filtration criterion

• stability

2. Preparation of :

a) a mixture

b) a compound

using iron filings and sulphur powder and distinguishing between these on the basis of:

(i) appearance, i.e., homogeneity and heterogeneity

(ii) behaviour towards a magnet

(iii) behaviour towards carbon disulphide as a solvent

(iv) effect of heat

3. Separation of the components of a mixture of sand, common salt and ammonium chlo-

ride (or camphor)
