Answer:
Giving away protons to the water molecules
Explanation:
When acids are mixed with water the following reaction takes place:
H^+(aq) + H2O(l) ------> H3O^+(aq)
Hence when acids are added to water, acids donate a proton to water to form the oxonium ion H3O^+ by coordinate covalent bonding. Note that acids contain the hydrogen ion H^+

A general formula of an acid always start with an hydronium ion or H+. The general formula of an acid have to end with an anion. As acids, these compounds are named starting with the prefix "hydro-," then adding the first syllable of the anion, then the suffix "-ic."
