Vedclass · Answer

(B) The reaction between a copper salt (e.g.,$CuSO_4$) and potassium ferrocyanide $(K_4[Fe(CN)_6])$ in the presence of acetic acid results in the formation of copper ferrocyanide $(Cu_2[Fe(CN)_6])$.This compound appears as a characteristic chocolate-brown precipitate.The chemical equation is: $2Cu^{2+} + [Fe(CN)_6]^{4-} \rightarrow Cu_2[Fe(CN)_6] \downarrow$ (chocolate-brown).

When acetic acid and $K_4[Fe(CN)_6]$ are added to a copper salt solution,which substance forms a chocolate-brown precipitate?
