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 Cu2+ (aq) + S2– (aq) ⇌ CuS (s) is high because the solubility product is low.
a) (A) is false and (R) is true.
b) Both (A) and (R) are false.
c) Both (A) and (R) are true but (R) is not the explanation for (A).
d) Both (A) and (R) are true but (R) is the explanation for (A).
