What should you do if you get stung by a bee?!

2. Neautralisation
This is the process where you make a solution neutral (neither acidic or alkaline).
For example:
Bee stings are acidic. They feel better is you rub toothpaste on them. Toothpaste is an alkaline and therefore neutralises the acidic sting.

3. What do you get when they join up?
Neutralisation
Neutralisation is when an acid and an alkali cancel each other out and the solution becomes neutral.
All acids contain hydrogen (H) particles.
All alkalis contain hydroxide (HO) particles.
What do you get when they join up?

4. Neutralisation
When an acid and an alkali join up you get HOH, which we write as water (H2O).
Neutralisation happens when you mix the right amounts of acidic and alkali solutions together.
Neutral solutions have a pH of 7.
