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.
About Neutral Substances
- 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.
