Explanation:
The acetic acid release a proton to water, to produce acetate and hydronium.
This is a weak acid.
The sulfuric acid release 2 protons to water to produce sulfate and hydronium.
This acid is considered as strong, but it is only strong in the first dissociation. The second dissociation is weak, with a Ka.
Carbonate takes a proton from water, to become bicarbonate (In this case, the carbonate behaves as a base).
Bicarbonate release a proton to ammonia, to make ammonium and carbonate anion.
Amonium cation release a proton to the hydroxide to make ammonia and water.
