Reaction Y is a redox. Zinc atom undergo oxidation by losing electron to form zinc ion. Oxidation number of zinc changes from 0 to +2. Copper (II) ion undergo reduction by gaining electron to form copper atom. Oxidation number of copper (ii) ion decrease from +2 to 0.
b) i) iron (ii) ion in compound R has 2+ oxidation number. Thus compound R is Iron (II) Chloride. Iron (III) ion in compund S has 3+ oxidation number. Thus compund S is iron (III) chloride.
 ii) oxidising agent = bromine water
Observation = Green R solution changes to brown.
