Question

Consider the following reaction in aqueous medium at 25^oC.

The equilibrium of above reaction shifts towards left in the presence of

• (A) Cl^-
• (B) SCN^-
• (C) 

  

• (D) CN^-

Answer 1

The Correct Option is A, C, D

Explanation:
The ions ${\mathrm{Cl}}^{-},{\mathrm{SCN}}^{-}$ and ${\mathrm{CN}}^{-}$ will form precipitate with ${}_{\mathrm{Cu}}^{\mathrm{I}}.$ Hence, the equilibrium willshift towards left.
