Neutralisation reaction

• metal oxides + acid -> salt + water
• metal hydroxides + acid -> salt + water
• metal hydroxides + acid -> salt + water + CO2
• ends with OH - hydroxide
• if it ends with CO 3 - carbonate
• Ends with O - oxide
• Negative ions of the acid combines with the posite ions from the base to form a salt and water
• When acid reacts with metal carbonates, the reaction still forms salt and water and also carbon dioxide
• All salts produced from a neutralisation reaction are all soluble - so they can dissolve
• To make a soluble salt, we need to react in acid with an insoluble base like :

  • metal hydroxide
  • metal oxide
  • metal carbonate
• Salts - contain positive ion which comes from base or alkali and contain negative ion which comes from acid
