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
