3.) Some acids, such as sulfuric acid (H2SO4) or carbonic acid (H2CO3), undergo multiple dissociation steps
to give off more than one proton. These are called polyprotic acids. Diprotic acids are polyprotic acids
which dissociate to give off 2 protons. Triprotic acids dissociate to give off 3 protons. We write the
chemical equations for these dissociations in multiple steps, whereby one proton is ionized in the first
step, then some of the product reacts again to produce another proton in the next step. For this
problem, let's consider the dissociation of a generic diprotic acid H2A.
a.) Write two balanced equations illustrating the two dissociation steps for the generic diprotic acid.
Don't forget states of matter.
