polyprotic acids and bases in equations

when writing the proton transfer equilibria equations, do we need to automatically apply polyprotic acids/bases such that for example in H2SO4 it is H2SO4 + H2O -> H3O+ + SO4 2- ? or would it still be HSO4 - ?

If you're writing the proton transfer equation, you should assume that it refers to removing 1 proton - so your conjugate base would be HSO4-, not just SO4-.

If at anytime you are confused at these types of questions, you could look at the chemical equation to see if all the hydrogen atoms are accounted for in the reactants and products.

When showing a polypeptide acid dissociating it should have both steps right? Or should we simplify into 1 step
