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
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.
neutralisation1
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?

neutralisation2
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.
