Question

Match these items.

1. acid _ H +
2. base _ H 3 O +
3. litmus _ pH 14
4. strong base _ charged particles
5. ions _ OH -
6. hydronium _ indicator

Answer 1

An acid would have to contain H+ ions

Hydronium ions are commonly known as H3O+

A strong base will have a pH of 12-14.

Ions are known as charged particles.

Bases contain OH^- ions.

Colored Litmus paper is an indicator.

Answer 2

Litmus is an indicator
Charged particles are ions
Acids contain H+ ions
Bases contain OH - ions
Hydronium ions are H3O+

Now, I have to take issue with the last one
A base of pH 14 is not a strong base, it would be a highly concentrated base. A strong base is a base that completely deionizes in water.

But technically, for the purpose of your answer strong base = pH 14
