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^+#.
