Question

(1)Write the ionic equation for the reaction
(2) the ioninc equation can be represented by half equation . Write these equation
(3) explain why this is a redox reaction.​

Answer 1

Answer:

The given reaction is:

Zn+H2So4 = ZnSo4+H2

 1. The ionic reaction is as follows:

Zn (solid) + 2H^+  (aqueous) + So4^2- (aqueous) ⇔ H2 (gas) + Zn^2+ (aqueous) + 2So4^2- (aqueous)

2. Yes it can be written in terms of two half reactions where the Cl ions are omitted and only the ions undergoing oxidation and reduction are included. These half reactions are:

Zn ⇔  (Zn^2+) + 2e^- and (2H^+) + 2e^- ⇔ H2

3. This reaction is a redox reaction as oxidation and reduction are taking place simultaneously. While zinc gets oxidized, hydrogen sulphate gets reduced.
