Making Salt

MAKING SALT

Aim:
To produce sodium chloride salt by carrying out a neutralisation reaction

Equipment:
50ml and 200ml beakers, dilute HCI, dilute NaOH, 25ml measuring cylinders, a glass stirring rod, spotting tile, Universal Indicator solution, tripod, gauze mat, Bunsen burner, evaporating basin

Method:
1. Using the measuring cylinder measure 10ml of HCI and pour it into your 50ml beaker. Add dilute NaOH of few drops 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 the solution to a spotting tile. Test its pH using Universal Indicator

3. 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

4. Pour the neutral solution into an evaporating basin and evaporate the water out of the solution using the equipment set up.
