The equilibrium `2 CuIhArr Cu+Cu^(II)` In aqueous medium at `25^@C` shifts towards the left in the presence ofA. `NO^(ɵ)`B. `Cl^(ɵ)`C. `SCN^(ɵ)`D. `CN^(ɵ)`

Answer» Correct Answer - B::C::D
`(b,c,d) 2Cu^(o+)hArr Cu+Cu^(2+)`
`Cl^(ɵ)` and `CN^(ɵ)` both make ppt. with `Cu^(o+)` and hence drive the reaction to the left.
