Chemistry: Atoms First (2nd Edition)

- In the left beaker, the acid is totally dissociated; all the $HA$ dissociated into $H^+$ and $A^-$; therefore, this is a strong acid solution. - In the right beaker, the acid is not totally dissociated; part of the $HA$ didn't dissociate into $H^+$ and $A^-$; therefore, this is a weak acid solution. - So, identify if the acid is strong or weak, and select the respective beaker.
