Neutralisation LO: • Describe how acids and alkalis can cancel each other out Unscramble these words: • Kliaal • Telspraic • Unltare What should you do if you get stung by a bee?!
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 neutralisesthe acidic sting.
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?
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.
