decomposed to \(\mathrm{H}_{2} \mathrm{S}\) and \(\mathrm{HCN}\) by \(HNO_{3}\)
\(\mathrm{NaCN}+\mathrm{HNO}_{3} \rightarrow \mathrm{NaNO}_{3}+\mathrm{HCN}\)
\(\mathrm{Na}_{2} \mathrm{S}+2 \mathrm{HNO}_{3} \rightarrow 2 \mathrm{NaNO}_{3}+\mathrm{H}_{2} \mathrm{S}\)
These will escape from the solution and will not interfere with the test for halogens.
