The Aim: To produce sodium chloride salt by carrying out a neutralisation reaction.
The Equipment needed: 50 ML and 200 ML beakers, dilute HCI (Hydrochloride 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.
The Method: 1) Using the measuring cylinder measure 10 ML of HCI and pour it into your 50 ML Beaker, Add dilute NaOH a few drops at a time while stirring with the glass rod.
2) Every 10-15 drops stop adding the NaOH and use the glass stirring rod to transfer a drop if the solution to a spotting tile. Test its pH using indicator.
3) Keep adding NaOH and testing the solution by repeating step 2. As you get closer to your neutral you may need 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.
I am a student at in Uru Mānuka. In 2020 I was a year 9 and in 2021 I will be a year 10. This is a place where I will be able to share my learning with you. Please note....some work won't be edited - just my first drafts, so there may be some surface errors. I would love your feedback, comments, thoughts and ideas.
