Question

On heating lead nitrate in a boiling test tube, a yellow residue left behind and a

brown gas ‘X’ is formed along with oxygen gas.

a. Write the balanced chemical equation for this reaction.

b. Identify the brown gas ‘X’ evolved.

c. Identify the type of reaction.​

Answer 1

Answer:

(a) 2Cu(NO3)2 → 2Cu + 4NO2+O2

(b) The brown gas 'X' has to be nitrogen dioxide.

(c) This type of reaction falls under the category of Decomposition reactions.

(d) The pH of the aqueous solution of gas X would be less than

The oxides of non metals are generally acidic in nature. Therefore, their aqueous solutions would exhibit acidic nature.
