In the reaction of Cu with HNO 3, it is nitrate ion not the hydrogen ion, which oxidises Cu.

Q. In the reaction of copper with nitric acid,

$C u$ is oxidised to $C u^{2 +}$ ion by hydrogen ion

$C u$ is oxidised to $C u^{2 +}$ ion by nitrate ion

$C u$ is reduced by hydrogen ion

Both(b) and (c)

In the reaction of $C u$ with $H N O_{3}$ , it is nitrate ion not the hydrogen ion, which oxidises $C u$ .

Q. In the reaction of copper with nitric acid,

Cu is oxidised to Cu2+ ion by hydrogen ion

Cu is oxidised to Cu2+ ion by nitrate ion

Cu is reduced by hydrogen ion

Both(b) and (c)

In the reaction of Cu with HNO3​, it is nitrate ion not the hydrogen ion, which oxidises Cu.
