In acidic solution, the sulfate ion can be used to react with a number of metal ions. One such reaction is
SO4^2-(aqu) + Sn^2+(aqu) -> H2SO3(aqu) + Sn^4+(aqu)
Since this reaction takes place in acidic solution, H2O(l) and H+(aqu) will be involved in the reaction. Places for these species are indicated by the blanks in the following restatement of the equation:
SO4^2-(aqu) + Sn^2+(aqu) + ____ -> H2SO3(aqu) + Sn^4+ + _____
What are the coefficients of the reactants and products in the balanced equation above? Remember to include H2O(l) and H+(aqu) in the appropriate blanks.
