A neutral substance is one which is not an acid or a base. It has a pH of 7.

All substances with a pH of 7 are neutral.

Neutral substances are not as corrosive as acids and bases.

Salts and water are neutral substances which are formed during neutralisation reactions.

A neutral substance is one which does not form any free Hydrogen ions or Hydroxide ions when in solution producing a solution of pH 7.

All substances with a pH of 7 are neutral.

Salts are neutral substances because they do not contain any H⁺ or OH^- parts to the compound.

A neutral solution is one which contains an equal concentration of H⁺ ions and OH^- ions.
