Question

Identify the oxidation and reduction process in;
(I)Zn + Hcl→H2 + ZnCl2.
(ii)Al + CuCl→AlCl3 +Cu. (III)Write out their half equation.​

Answer 1

i) In this reaction , HCl is reduced to H2 and Zn is oxidised to ZnCl2.

ii) In this reaction , Al is oxidised to AlCl3 and CuCl is reduced to Cu.

iii) a)Zn → Zn2+ + 2e− and 2H+ + 2e− → H2

b)Al → Al3+ + 3e−
