State what is observed when:
Excess of ammonia a passed through an aqueous solution of lead nitrate
Explain why only all-glass apparatus should be used for the preparation of nitric acid by heating concentrated sulphuric acid and potassium nitrate.
Nitric acid is highly corrosive and therefore destroys rubber and cork of the apparatus.
Concentrated sulphuric acid si both an oxidising agent and a non-volatile acid.
Write one equation each to illustrate the above-mentioned properties of a sulphuric acid.
Write balanced chemical equations for the following reactions:
Ethane and oxygen in the presence of molybdenum oxide
