Question

Neutral substances have a pH of ______.

Answer 1

Neutral substances have a pH of 7.

Explanation:

Neutral substances have a pH of 7 because they possess an equal balance of hydrogen ions and hydroxide ions. This perfect balance prevents the solution from being either acidic or alkaline, keeping it right at the centre of the 0-14 scale. Pure water is the most common example of a neutral substance meeting this exact criterion.
