$CuS$

Vedclass · Answer

(B) Concentrated $HNO_3$ acts as a strong oxidizing agent. $CuS$ (Copper sulfide) reacts with concentrated $HNO_3$ to form soluble copper$(II)$ nitrate,sulfur,and nitrogen dioxide gas. The reaction is: $CuS + 8HNO_3 \rightarrow Cu(NO_3)_2 + S + 8NO_2 + 4H_2O$. $BaSO_4$ is insoluble in acids. $PbS$ and $HgS$ are generally insoluble in concentrated $HNO_3$ under standard conditions compared to $CuS$.

Which of the following is soluble in concentrated $HNO_3$?
