Question

on heating blue coloured powder of copper nitrate in a boiling tube copper oxide (black) and oxygen and a brown x gas are formed
i) Identify the brown x gas
ii) what could be the pH range of the aqueous of the solution of gas x​

Answer 1

Answer:

When this anhydrous copper (II) nitrate is further heated it gives a black residue of copper oxide and also gives out a brown gas i.e., of nitrogen dioxide and a colorless gas which is of oxygen. Therefore, the gases X and Y are oxygen and nitrogen dioxide respectively.
