• Acid


  An acid is a proton donor
• Base


  A base is a proton acceptor
• ionisation 


  the reaction of a molecular substance with water to produce ions
• Strong acid


  An acid that ionises almost completely in aqueous solution
• Weak Acid


  An acid that ionises only partially in an aqueous solution
• Dissociation 


  The splitting of an ionic compound into its ions
• Strong base


  A base that dissociates almost completely in an aqueous solution
• amphoteric Substance 


  A substance that can act as either an acid or a base
• Salt


  a substance in which the hydrogen of an acid has been replaced by a cation
• Hydrolysis of a salt

  a reaction of an ion (from a salt) with

  water
• Neutralisation 


  a chemical reaction in which an acid and a base react so that neither is in excess
• Standard solution 


  a solution of known concentration
