For the following Assertion and Reason, the correct option is
Assertion (A) : When $Cu$ (II) and sulphide ions are mixed, they react together extremely quickly to give a solid.
Reason (R) : The equilibrium constant of ${Cu}^{2 +} (aq) + S^{2 -} (aq) ⇌ CuS (s)$ is high because the solubility product is low.

Question

For the following Assertion and Reason, the correct option is

Assertion (A) : When $Cu$ (II) and sulphide ions are mixed, they react together extremely quickly to give a solid.

Reason (R) : The equilibrium constant of ${Cu}^{2 +} (aq) + S^{2 -} (aq) ⇌ CuS (s)$ is high because the solubility product is low.
