How can you teak the difference between a weak acid and strong acid?

A strong acid will dissociate completely whereas a weak acid will not. Weak acids have a K constant <10^-3.

Weak acids do not completely dissociate in chemical reactions involving a solvent, while strong acids do. Generally if you are given a problem that includes a value of Ka (the acidity constant), then you will be dealing with a weak acid because strong acids do not have these constants. An acid is definitively weak if it has a Ka value is less than 10^(-3).
