Preparation of

Perform and classify the following reactions as physical or chemical changes:

• Iron with copper sulfate solution in water
• Burning of magnesium ribbon in air
• Zinc with dilute sulphuric acid
• Heating of copper sulfate crystals
• Sodium sulfate with barium chloride in the form of their solutions in water

 Preparation of

1. A mixture
2. A compound

Using iron filings and sulfur powder and distinguish these on the basis of:

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

(ii) behavior with a magnet

(iii) behavior with a carbon disulfide as a solvent

(iv) effect of heat

Preparation of:

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

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

c) a colloidal solution of starch in water & egg albumin/milk in water & differentiate in between  on the basis of
