On heating blue coloured powder of copper(II) nitrate in a boiling tube copper oxide (black), oxygen gas and a brown gas X is formed. What could be the pH range of aqueous solution of the gas X ?

Solution

Copper(ll) nitrate decomposes on heating to form copper oxide, oxygen gas and brown coloured nitrogen dioxide $(N O_{2})$ gas. Latter is an oxide of a non-metal (nitrogen), therefore it combines with water to form an acidic solution whose pH is less than $7$ .
