When oh- and h+ ions are brought together, they quickly combine to form water molecules.
a. true
b. false

The correct answer is true.

Explanation:

When the ions OH- and H+ come into contact with each other, they briskly combine to produce the molecules of water. In this combination, a cation and an anion combine to exhibit a neutral state of their charges and produce molecules of water.  

Neutralization refers to a reaction in which a base like NaOH and an acid like HCl react quantitatively with each other, and in this kind of reaction salt and water are the products of the reaction.
