On this page would like you to create notes that cover the following points:

  • State the rule for a reaction between an acid and a metal
Metal + acid → salt + hydrogen (MASH)
eg. Aluminium + hydrochloric acid → aluminium chloride + hydrogen


  • State the rule for a reaction between an acid and a base (hydroxide)
Base + acid → salt + water (BASH)
eg. Sodium hydroxide + sulfuric acid → sodium sulfate + water


  • State the rule for a reaction between an adic and a carbonate
Carbonate + acid → salt + water + carbonate (CAWSaC)
eg. Calcium cabonate + nitric acid → calcium nitrate + water + carbon dioxide
