Making Salts -Science

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.

Method:

1. Using the measuring cylinder measure 10 ml of HCL and pour it into your 500 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 of the solution to a spotting tile. Test its pH using a 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.

 

Conclusion:

First, we have to do is we have to finish our work in our book before we can do the experiment. My friend who named Khush, he said if I and he can work together about the experiment. After I and Khush finish the work we rush and do the experiment, so first we have to do is get the equipment and then we have to put like 10 ml either acid or base after we got 10ml of either acid or base we pour it in our 50 ml beaker. For example, if we put 10 ml of acid then we have to put like a base and then mix it and put it in the spotting tile, but we only have to put like once and after we put once we have to put like 1 drop of universal indicator and if its turn red it means we need to put more base if it turns purple or blue it means we have to put acid until the colour of the acid turns it to green.  When it turns green we have to pour it into an evaporating basin and then evaporate the water out of the solution using the equipment set up shown above.
