Step-by-step solution
The ferric chloride reacts with the   K 4 Fe ( CN ) 6 and gives the ion exchange reaction and formed the compound Fe 4 Fe ( CN ) 6 3   and potassium chloride. 4 FeCl 3 + 3   K 4 Fe ( CN ) 6 → Fe 4 Fe ( CN ) 6 3   + 4 KCl Zinc chloride reacts with the sodium hydroxide and formed the Na 2 ZnO 2 as a product. In this reaction, the ferric chloride is reduced into ferrous chloride. 2 FeCl 3 + H 2 S → 2 FeCl 2   + S   + 2 HCl
