Answer: completely (100%) dissociates, producing a significant amount of H+ and OH- ions in solution, making it conduct electricity well.
Explanation:
A strong acid is one that ionizes or dissociate completely in water to yield its hydrogen ion (H+) as the only positively charged ion.
For example: Hydrochloric acid (HCl) dissociates completely in water to give hydrogen ion and chlorine ion
HCl(aq) --> H+(aq) + Cl-(aq)
A strong base, on the other hand, dissociates completely in water to yield an hydroxyl ion (OH-) as the only negatively charged ion. A good example is Sodium hydroxide NaOH
NaOH (aq) --> Na+(aq) + OH-(aq)
And since mobile and charged ions help transmit electric current, a strong acid or base produces significant amount of H+ and OH- ions that conduct electricity well.
