the molecules are donated to water molecules.
if a little of the acid remains after it is added to water, then it is a strong acid.
if a lot remains, then it is a weak acid.
same goes for bases.

In a weak acid molecule, only a small fraction of molecules will dissociate into ions in solution, leading to a lower concentration of H+ ions compared to a strong acid. In contrast, a strong acid molecule will completely dissociate into ions in solution, resulting in a higher concentration of H+ ions.
strong acid
When an acid dissolves in water, the molecules of the acid break apart into ions. Specifically, the acid molecules donate protons (H+ ions) to the water molecules, resulting in the formation of hydronium ions (H3O+) and negatively charged ions from the acid. This process is called ionization or dissociation.
Hydronium ion (H3O+) increases in concentration when a strong acid is added to water. This is because the strong acid donates a proton (H+) to water molecules, forming hydronium ions.
A strong aqueous acid readily dissociates in water, breaking apart into ions like H+ and an anion. This process creates more ions than molecules because the acid is highly conducive to ionizing in the aqueous solution. Consequently, a strong acid in water is usually mostly in ionic form rather than molecular form.
Hydrosulfuric acid (H2S) is a weak acid. It only partially ionizes in water, resulting in the presence of both undissociated molecules and dissociated ions. This differs from strong acids, which completely ionize in water.
When all of the molecules of an acid break apart in water, it is called complete dissociation. This results in the formation of ions, with the acid molecule donating a proton to water to form hydronium ions and the conjugate base.
It means the acid disassociates to almost 100% in solution. HCl H + and Cl - Happens to almost all the molecules of hydrochloric acid in this simplified example.
Dilution of an acid is usually an exothermic process because it releases heat as the acid molecules mix with water to form a solution. This heat is a result of the strong interactions between the acid molecules and water molecules during the dilution process.
How about the ever faithful hydrochloric acid and sodium hydroxide: HCl + NaOH --> NaCl + H20. Strong Acid + Strong Base = Salt & Water
Oleic acid is a fatty acid that is insoluble in water due to its long hydrocarbon chain. When added to water, oleic acid will form a separate layer on top of the water due to its hydrophobic nature. This separation is due to the difference in polarity between the water molecules and the nonpolar oleic acid molecules.
