  1. 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?!

  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 neutralisesthe acidic sting.

  3. 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.

  5. Useful reactions Explain what Milk of Magnesia is and why it is so useful.

  6. Activity • Answer questions 1-8on page74/5.
