Excess aqueous sodium hydroxide is added to separate samples of $N X_{2} O X_{3}$ , $N X_{2} O X_{4}$ and $N X_{2} O X_{5}$ . The nitrogen-containing sodium salts obtained are, respectively,

N X_{2} O X_{3}

is the anhydride of

HNO X_{2}

N X_{2} O X_{3} + 2 NaOH 2 NaNO X_{2} + H X_{2} O

N X_{2} O X_{4}

is a mixed anhydride and disproportionates:

N X_{2} O X_{4} + 2 NaOH NaNO X_{2} + NaNO X_{3} + H X_{2} O

N X_{2} O X_{5}

is the anhydride of

HNO X_{3}

N X_{2} O X_{5} + 2 NaOH 2 NaNO X_{3} + H X_{2} O
