Write balanced equations and name the products formed when:

(a) Sodium hydrogen carbonate is added to nitric acid.

(b) Cupric oxide reacts with nitric acid

(c) Zinc reacts with dilute nitric acid

(d) Concentrated nitric acid is heated

How will you prepare the following from nitric acid?

(a) Sodium nitrate

(b) Copper nitrate

(c) Lead nitrate

(d) Magnesium nitrate

(e) Ferric nitrate

(f) Aqua regia

Correct the following, if required:

(a) HNO₃ is a strong reducing agent.

(b) NaNO₃ gives NO₂ and O₂ on heating.

(c) Constant boiling nitric acid contains 80% nitric acid by weight.

(d) Nitric acid remains colourless even when exposed to light.

(e) Magnesium reacts with nitric acid to liberate hydrogen gas.

The nitrate salt which does not give a mixture of NO₂ and O₂ on heating is:

1. AgNO₃
2. KNO₃
3. Cu(NO₃)₂
4. Zn(NO₃)₂
