UNIT 1- Neutralisation

Question 1

what is neutralisation

Answer 1

If an acid is added to an alkali (in the right quantity) it will neutralise the substance, making water. This is how antacids treat indigestion (too much acid in the stomach)

Question 2

To neutralise an acid:

Answer 2

1) Add a small volume of an alkali to the acid

2) Stir the solution and use the stirring rod to test the pH on pH paper

3) Continue to repeat steps 1 & 2 until the substance is nearly neutral. At this point, add the alkali a couple of drops at a time, until the solution is pH 7.
