Glossary

  • Acid: any substance that donates H+ ions; A solution that contains more H+ than OH- ions
  • Base: any substance that removes free H+ from a solution¬†
  • Alkali: any substance that donates OH- ions into a solution; A solution that contains more OH- than H+ ions
  • pH: the concentration of hydrogen ions (H+) in a solution
  • Acidic: a solution containing excess H+ ions; a solution with a pH less than 7
  • Alkaline: a solution containing fewer H+ than OH- ions; a solution with a pH greater than 7
  • Neutral: a solution where there are exactly the same number of H+ and OH- ions
  • Dissociation: molecules in solution break apart into ions and then re-form again
  • Buffer: a molecule that can both accept H+ and donate that H+ ions
  • Denaturation: alteration of a molecule's shape and structure leading to loss of function following rearrangement of its atoms
  • Neutralisation: combination of an acid and an alkali to form a salt and water
  • Salt: a molecule formed by the combination of an acid without its free H+ ions and an alkali without its OH- ions
