Stability of
Nitrates and Hydroxides
Similarly, nitrates of other metals
decompose to the oxide, nitrogen dioxide and oxygen.
Hydroxides of the other metals
however are not as stable and decompose on heating to the
oxide and water.
The reaction is always accompanied
by the evolution of the dark brown nitrogen dioxide gas, and
often by a change in the color of the solid.
