Making salts
Aim: To produce sodium chloride salt by carrying out a neutralisation reacting.
Method:
- Using the measuring cylinder measure 10 mL of HCl and pour it into your 50mL beaker. Add dilute NaOH a few drops at a time while stirring with the glass rod.
- 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.
- 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 into an evaporating basin and evaporate the water out of the solution using the equipment set up shown above.
