Question

A strong acid OR base is one that:

Answer 1

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.
