Answer 1

`SO_(3)^(2-)(aq.)+2OH^(-)(aq.)\rightarrow SO_(4)^(2-)(aq.)+H_(2)O(l)+2e^(-)`

Step-by-step explanation:

The given reaction is an example of oxidation reaction. The step-by-step balancing procedure has been shown below:

Chemical equation:
`SO_(3)^(2-)(aq.)\rightarrow SO_(4)^(2-)(aq.)`

Balance H and O in basic medium:
`SO_(3)^(2-)(aq.)+2OH^(-)(aq.)\rightarrow SO_(4)^(2-)(aq.)+H_(2)O(l)`

Balance charge:
`SO_(3)^(2-)(aq.)+2OH^(-)(aq.)\rightarrow SO_(4)^(2-)(aq.)+H_(2)O(l)+2e^(-)`

Balanced chemical equation:

`SO_(3)^(2-)(aq.)+2OH^(-)(aq.)\rightarrow SO_(4)^(2-)(aq.)+H_(2)O(l)+2e^(-)`
