Acids

• What does an acid release in an aq solution?

  H+ ions
• Bases


  Neutralise acids
• Alkali


  a soluble base that releases OH- ions in aqueous solutions
• Strong acids


  completely dissociate when dissolved in water
• Weak acids


  slightly dissociate when dissolved in water, giving an equilibrium mixture
• When is a salt formed

  when the H+ ion of an acid is replaced by a metal ion or an ammonium ion
• Neutralisation reactions


  form salts
• neutralisation reaction equations


  acid+base=salt+water

  acid+carbonate=salt+water+carbon dioxide
• concordant tires
