The question asks me to balance the following redox reaction
using the half-reaction method:
10) Co(OH)3 (s) + Sn (s) --> Co(OH)2
(s) + HSnO21- (aq) (basic solution)
Balance the following redox reactions, in base, using the
half-reaction method. Clearly identify each balanced half-reaction
and the overall balanced equation.
C3H8O2 (a) + Cr2O72– (aq) C3H4O4 (aq) + 2 Cr3+ (aq)
3. Balance the following redox reactions that occur in
acidic solution using the half-reaction method.
a. Cr(s) + NO3-(aq) → Cr3+(aq) + NO(g)
b. CH3OH(aq) + Ce4+(aq) → CO2(aq) +
Ce3+(aq)
c. SO32-(aq) + MnO4-(aq) → SO42-(aq) +
Mn2+(aq)
4. Balance the following redox reactions that occur in
basic solution using the half-reaction method.
a. PO33-(aq) + MnO4-(aq) → PO43-(aq) +
MnO2(s)
b. Mg(s) + OCl-(aq) → Mg(OH)2(s) + Cl-(aq)
c. H2CO(aq) + Ag(NH3)2+(aq) → HCO3-(aq) + Ag(s) +
NH3(aq)
balance each of the following oxidation/reduction reactions
utilizing the half reaction method,
H2O2 (aq) + Cl2O7 (aq) → ClO2- (aq) + O2 (g) in basic
solution
Balance by the half-reaction method, both in acid and in
base:
Cr2O3 (s) + H2O2
(aq) -----> CrO42- (aq) + H2O
