Write a balanced equation for the preparation of the following salt: Copper sulphate from Copper carbonate.

Give a chemical test to distinguish between the following pair of chemicals: Sodium chloride solution and Sodium nitrate solution.

Complete the following table which refers to the conversion of ions to neutral particles.

State one relevant observation for of the following:

Barium chloride solution is slowly added to sodium sulphate solution.

State one relevant observation for of the following:

Anhydrous calcium chloride is exposed to air for some time.

Write a balanced chemical equation for the preparation of ammonium sulphate by using the method of titration.

Write a balanced chemical equation for the preparation of zinc carbonate by using the method of precipitation.

Write a balanced chemical equation for the preparation of copper sulphate by using the method of neutralization.

Identify the salt Q from the following observation:

Salt Q is white in colour. On strong heating, it produces buff-yellow residue and liberates a reddish-brown gas. Solution of salt Q produces chalky white insoluble precipitate with an excess of ammonium hydroxide.

Identify the salt P from the following observations:

Salt P has light bluish-green colour. On heating, it produces a black coloured residue. Salt P produces brisk effervescence with dilute $\mathrm{HCl}$ and the gas evolved turns lime water milky, but no action with acidified potassium dichromate solution.
