FREE Expert Solution
We are being asked to determine the coefficient of H+ when the given redox reaction is balanced in an acidic solution.
When balancing redox reactions under acidic conditions, we will follow the following steps.
Step 1: Separate the whole reaction into half-reactions
Step 2: Balance the non-hydrogen and non-oxygen elements first
Step 3: Balance oxygen by adding H2O to the side that needs oxygen (1 O: 1 H2O)
Step 4: Balance hydrogen by adding H+ to the side that needs hydrogen (1 H: 1 H+)
Step 5: Balance the charges: add electrons to the more positive side (or less negative side)
Step 6: Balance electrons on the two half-reactions
Step 7: Get the overall reaction by adding the two reaction
Balance the redox reaction under acidic condition:
When the reaction MnO2(s) <=> Mn2+(aq) + MnO4-(aq) is balanced in acidic solution, what is the coefficient of H+?
a. 0, it will be cancelled out
b. 6 on the product side
c. 4 on the product side
d. 6 on the reactant side
e. 4 on the reactant side
