It completely disassociates in water

Explanation:

A strong acid completely disassociates in water, meaning a strong acids conjugate base is a weaker base than water. That means that it does not have the ability to gain an H^+.

For example:

HCl is a strong acid, when it ionizes it disassociates into an H^+ and Cl^-atom. The Cl^- is neutral, in other words it cannot take an H^+ from the H_3O^+.
