PLEASE DON'T ANSWER IF YOU DON'T KNOW WHAT YOU'RE TALKING ABOUT.

Classify each of the following reactions as preoxidation, prereduction, or elimination of preadjustment reagent:

A) Reaction of Ce^3+ with AgO in concentrated mineral acid

B) Reaction of Fe^3+ with SnCl2

C) Reaction of Fe^3+ with solid Ag in 1M HCl

D) Boiling the solution of H2O2

E) Reaction of CO^2+ with H2O2 in basic solution

F) Reaction of Mn^2+ with S2O8^2- + Ag^+

G) Boiling the solution of S2O8^2-

H) Reaction of MnO4^- with H2O2 in acidic solution

Explanation / Answer

Preoxidation:

A) Reaction of Ce^3+ with AgO in concentrated mineral acid: Oxidized to Ce^4+

E) Reaction of Co^2+ with H2O2 in basic solution: Oxidized to Co^3+

F) Reaction of Mn^2+ with S2O8^2- + Ag^+: Oxidixed to Mn^3+

Prereduction:

B) Reaction of Fe^3+ with SnCl2: Reduced to Fe^2+

C) Reaction of Fe^3+ with solid Ag in 1M HCl: Reduced to Fe^2+

H) Reaction of MnO4^- with H2O2 in acidic solution: Reduced to Mn^6+

Elimination:

D) Boiling the solution of H2O2: Boiling is used to eliminate excess reagent so that it won
