Aim: To produce sodium chloride salt by carrying out a neutralisation reaction.
Equipment: 50 mL and 200 mL beakers, dilute HCI ( hydrochloric acid) , dilute NaOH ( sodium hydroxide) , 25 mL measuring cylinder, a glass stirring rod, spotting tile, Universal indicator solution, tripod, gauze mat, Bunsen burner , evaporating basin.
1 : Using the measuring cylinder measure 10 mL of HCI and pour it into your 50 mL beaker.
2 : Every 10-15 drops stop adding the NaOH and use the glass stirring rod to transfer a drop of the sulfate 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 shown above.
