What makes an acid either strong or weak?

A strong Bronsted acid is one that is more readily to donate a proton, while a weak Bronsted acid is less willing to give up its proton(s).

A strong acid or base is one which readily dissociates completely in water, and common examples include HCl and NaOH. Weak acids or bases only partially dissociated in water and a majority of the molecule will remain in its associated form when placed in water.

Whether it dissociate completely in water or not. Strong acid theoretically would dissociate 100% in water

A strong acid is one that dissolves completely into its ions in water. A weak acid would only partially dissolve. A weak acid would have a higher pH than a strong acid. Strong acids have pHs closer to 0 and less than pH 7.

Strong acids fully dissolve into its ions in water, so they have a high concentration of ions in a solution. This, the bonds between the hydrogen atom and another atom of the molecule are weak. Ions are easily broken apart by strong acids. Weak acids partially dissociated into its ions in water, so they have a low concentration of ions in solution. Thus, bonds between the hydrogen atom and another atom of the molecule are strong.

A strong acid is one that fully dissociates in water while a weak acid is one that only partially dissociates (equilibrium dictated by something called a Ka value).
