Ionic Equilibrium question

2020 · 2 Sep · Shift 1 · Q10

JEE MainChemistryIonic EquilibriumMCQ+4 / −1
For the following Assertion and Reason, the correct option is Assertion (A): When CuCuCu (II) and sulphide ions are mixed, they react together extremely quickly to give a solid. Reason (R): The equilibrium constant of Cu2+Cu^{2+}Cu2+(aq) + S2−S^{2-}S2−–(aq) ⇌ CuSCuSCuS(s) is high because the solubility product is low.
  1. A
    (A) is false and (R) is true.
  2. B
    Both (A) and (R) are true but (R) is not the explanation for (A).
  3. C
    Both (A) and (R) are true and (R) is the explanation for (A).
  4. D
    Both (A) and (R) are false.
