Question

In a titration, when the number of moles of the hydrogen ions equals of the number hydroxide ions, what is said to have happened?

Answer 1

Neutralization of strong acid with strong base.

Explanation:

Titrations can be represented by many chemical reactions, but in this question it is referring to an acid-base reaction. Acid-Base reactions can be divided into 4 types:
- strong acid + strong base
- weak acid + strong base
- strong acid + weak base
- weak acid + weak base.

A titration that compares `H^+` ion concentration with `OH^_` concentration is typically a strong acid + strong base titration. For all strong acid + strong base titrations where `[H^+]`= `[OH^-]` the system is said to be neutralized with the only reagent present under the specified condition is the salt, `[H^+]`= `[OH^-]` & pH = 7.00.
