Acids and bases

KEY DEFINITIONS pH: mathematical function that indicates the concentration of aqueous hydrogen ions, H+(aq) in a water-based solution. pH scale: a logarithmic mathematical scale that extends from 0 (very strong acid) to 14 (very strong alkali). At room temperature, a solution that has a pH equal to 7.0 is described as a neutral solution. Acidic pH or acidic solution: a solution

Making salts

The particular salt produced in any reaction between an acid and a base (or alkali) depends on: ♦ the acid used (hydrochloric acid produces chlorides, nitric acid produces nitrates, sulfuric acid produces sulfates) ♦ the metal in the base or alkali. Ammonia dissolves in water to produce an alkaline solution. It is used to produce ammonium salts. Ammonium salts are
