Weak vs Strong Acids

Postby Ashley Kao 1H » Sun Nov 24, 2019 5:28 pm

How do we determine if an acid is strong or weak? Is strength based off of electronegativity?

Most acids are weak, but an acid that fully dissolves into ions is a strong acid while an acid that doesn't fully dissolve into ions is a weak acid.

Acids where the anion is stable when dissolved is a strong acid. In other words, the acids that readily give off their H+ is a strong acid. Therefore, acids such as HBr, HI are strong acids while HF is a weak acid.

I agree that the strength of an acid is usually determined by its pH or H+.
