Making salts


Aim: To produce sodium chloride salt by carrying out a neutralisation reaction
  1.  using the measuring cylinder measure 10 ml of HCI and pour it into your 50 ml beaker. add dilute NaOH a few at a time while stirring with a glass rod. 
  2. Every 10-15 drops stop adding the NaOH  and use the glass stirring rod to transfer a drop of a solution to a spotting tile. Test it's pH using universal indicator.
  3. Keep adding NaOH and test the solution by repeating step 2. As you get closer to neutral you may need to test the solution after every drop.
  4. Pour the neutral solution into an evaporating basin and evaporate the water out of the solution using the equipment needed
