1. The problem statement, all variables and given/known data I'm having problems understanding amphoteric acids and bases. I know amphoteric means that it can act as an acid or base, but when the question asks me to write the equation to support this statement, I always get it wrong 2. Relevant equations HSO4^-1 is an amphotheric ion. Write chemical equations to show this ion acting as a) an acid b) a base 3. The attempt at a solution For a) I wrote HSO4^-1 + H2O -> SO4^-2 + H3O^+ but, on the answers it is HSO4^-1+OH^-1 -> SO4^-2 + H2O For b) I wrote HSO4^-1 + H2O -> H2SO4 + OH^-1 but on the answers it is HSO4^-1 + H3O+ ->H2SO4 + H2O I have no idea why I'm wrong Could someone help explain this to me?
