*pure products

• Pure Products


  are needed to carry out a chemical reaction as impurities in medicine froe example could stop the medicine from working or harm the patient
• Simple Reactions 


  there is only one products produced, eg;

  • magnesium + oxygen -> magnesium oxide
• Other Reactions

  may produce more than one product, eg;

  • silver nitrate + sodium chloride -> sodium nitrate + silver chloride
  • sulfuric acid + sodium hydroxide -> sodium sulfate + water
  • barium chloride + sodium sulfate -> barium sulfate + sodium chloride
  • lead nitrate + potassium iodide -> potassium nitrate + lead iodide
  • copper carbonate + hydrochloric acid -> copper chloride +water + carbon dioxide
• when there is more than one product they are mixed together and need to be seperated and purified to produce whichever pure substance you want.

  the products may also be mixed up with some pure products you want and some reactants if not all used up in the reaction.
