The equation which is balanced and represents the correct product is….

Options

A. `CuSO_(4) + 4KCN rarr K_(2)[Cu(CN)_(4)] + K_(2)SO_(4)`
B. `Li_(2)O + 2KCl rarr 2LiCl + K_(2)O`
C. `[CoCl(NH_(3))_(5)]^(+) + 5H^(+) rarr Co^(2+) + 5NH_(4)^(+) + Cl^(-)`
D. `[Mg(H_(2)O)_(6)]^(2+) + ("EDTA")^(4-) underset(NaOH)overset("Excess")rarr [Mg("EDTA")]^(2+) + 6H_(2)O`

Answer

C

Explanation

(A) `2CuSO_(4) + 10KCN rarr 2K_(3)[Cu(CN)_(4)] + 2K_(2)SO_(4) + CN_(2)`
(B) Reaction is not favourable as `K_(2)O` is unstable
(D ) Not balanced w.r.t charge
