Covalently bonded H-Cl gas reacts with water to form ions. People usually save time by writing H+ + Cl-, and that the H+ makes the acid. In water, however, the + ion present is the hydronium ion, H3O+.

HCl(g) + H2O ===> H3O+ + Cl-

Acid in its powdered form does not have the properties of an acid. it is just a solute (something that can be dissolved). when dissolved into water, the solute breaks up into ions (positively or negativel charged protons) and this is what allows acid to be produced. If you add a sufficient amount of base, you will be left with water and a salt. Water, because acids contain H+ ions (this is what makes them acids) and bases contain OH- ions (this is what makes them bases), and when you put two hydrogens and one oxygen together, you obtain water. The salt is what is left after the acid and the base have joined that is not H+ ions or OH- ions. If you want to learn more about what is the role of water in acid production, you should check out the Bronsted-Lowry theory on acids and bases. This theory can be found by using any internet search engine.

Water Disassociates into H+ and OH- ions. The extra H+ make acidic conditions.

Or the polar H-Cl bond undergoes nucleophilic reactions?
