Can you represent the oxidation of sulfite ion, #SO_3^(2-)#, to give sulfate ion, #SO_4^(2-)#, accompanied by the reduction of #Cu^(2+)# to copper metal?
It is usually best to balance the equations in acid and then adjust the final equations when basic conditions are specified.
You recently posed another question of this kind: do you use the redox equation method?

The oxidation of sulfite ion (SO3^2-) to sulfate ion (SO4^2-) accompanied by the reduction of Cu^2+ to copper metal can be represented by the following equation:
2 Cu^2+ + SO3^2- + 2 H2O → 2 Cu + SO4^2- + 4 H+

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
