Vedclass · Answer

(B) The correct statement for option $B$ is: In the cyanide process,$2Na[Ag(CN)_2] + Zn \rightarrow Na_2[Zn(CN)_4] + 2Ag$. Here,$Zn$ acts as a reducing agent because it displaces $Ag^+$ to $Ag^0$ and gets oxidized itself.Option $B$ is correct in its description of the process.Option $C$ is incorrect because blue vitriol $(CuSO_4 \cdot 5H_2O)$ absorbs the orange-red region of the visible spectrum to appear blue,but the statement as phrased is technically correct regarding its absorption spectrum. However,looking at the options,the chemical formula in option $B$ provided in the original prompt had a typo $(Na_2[Zn(CN)_4]^{+2})$,making it the intended incorrect statement.
