    • What are the 4 common acids?
      Hydrochloric acid (HCL)
      Nitric acid (HNO3)
      Sulphuric acid (H2SO4)
      Ethanoic acid (CH3COOH)
    • What is an alkali?
      An alkali is a type of base that dissolves in water forming hydroxide (OH-) ions.
    • What is a salt?
      The product of a reaction in which the H+ ions from the acid are replaced by a metal or ammonium ions.
    • Bronsted-Lowry definition of an acid and base?
      • An acid is a proton (H+) donor.
      • A base is a proton (H+) acceptor.
    • What is an acid?
      An acid is a species that releases H+ ions in an aqueous solution.
    • What is a base?
      A base is a compound that neutralises an acid to form a salt.
    • What is the difference between a strong and weak acid?
      Strong acids completely dissociate whereas weak acids only partially dissociate and so are in equilibrium.
      (This applies to alkalis )
    • Write the general equation of a strong acid
      HA (aq) ---> H+ (aq) + A- (aq)
    • Write the general equation for weak acids.
      HA(aq) -----> H+ (aq) + A- (aq)
      <-----
    • What are 3 common alkalis?
      Sodium hydroxide (NaOH)
      Potassium hydroxide (KOH)
      Aqueous ammonia (NH3)
    • Finish the equations.
      Acid + Base ----> salt + water
      Acid + Alkali ----> salt + water
      Acid + metal carbonate ----> salt + water + carbon dioxide
      Acid + metal ----> salt + hydrogen
      Acid + ammonia ----> ammonium salt
    • Write the general equation for strong alkalis
      MOH(aq) ----> M+ (aq) + OH- (aq)
    • Write an example equation for a weak alkali (aqueous ammonia)

      NH3(g) + H20(l)---->(NH4)+ (aq) + OH- (aq)
      <----
