Question

on heating blue coloured powder of copper nitrate in a boiling tube ,black copper oxide Oxygen and brown gas X is formed .
a) Identify the type of reaction and the gas X.
b) write balanced chemical equation of the reaction .
c) write the pH range of aqueous solution of the gas X.

Give the answers.. ​

Answer 1

Answer:

Cu(2NO3) --------- CuO +NO2 +O2

Gas is No2 and reaction is decomposition reaction and ph range 8.6

Answer 2

Answer:

a) Decomposition reaction

x = nitrogen dioxide NO2

b) Cu(NO3)2 -- CuO2 +2NO2

c)non-metallic oxides are acidic so it is an acidic solution
