If none, leave box blank. Submit Answer Retry Entire Group 4 more group attempts remaining

Answer 1

Answer:-

From the given half reactions and their standard reduction potential.

(1) The weakest oxidizing agent = Zn²⁺(aq) because it has the most negative standard reduction potential

(2) The strongest reducing agent = Zn²⁺(aq)

(3) The strongest oxidising agent = I₂ (s)because it has the most positive standard reduction potential

(4) The weakest reducing agent = I_2(s)

(5) Will Zn(s) reduce I₂(s) to I^-(aq) = Yes because it will have positive standard cell potential

(6) the speciescan be reduced by Sn(s) = I₂(s)
