Making salts

AIM-To produce sodium chloride salt by carrying out a neutralisation reaction.

METHOD-

• Using the measuring cylinder measure 10mL of HCI an pour it into your 50mL beaker. Add dilute NaOH a w drops at a time while stirring with a glass rod.
• Every 10-15 drops stop adding the NaOH an use the glass stirring rod to transfer a drop of the solution to a spotting tile. Test its pH using Universal Indicator.
• Keep adding NaOH and testing the solution by repeating step 2. As you get closer to neutral you may need to test the solution after every drop.
• Pour the neutral solution into an evaporating basin an evaporate the water out of the water of the solution using the equipment set up shown above.
