Question

Identify the species being oxidized and reduced in each of the following reactions:

a. Cr+ + Sn4+ Cr3+ + Sn2+

Answer 1

Explanation:

a. 2 Cr+ + Sn4+  Cr3+ + Sn2+ Cr+

: oxidized, Sn4+: reduced



b. 3 Hg2+ + 2 Fe (s) 3 Hg2 + 2 Fe3+ Hg2+: reduced, Fe: oxidized

c. 2 As (s) + 3 Cl2 (g)  2 AsCl3 As: oxidized, Cl2: reduced
