3.1.12.3 The Ionic Product of Water, Kw

Question 1

What is Kw?

Answer 1

An equilibrium consant for the dissociation of water
Called the ionic product of water
Increases as temperature increases
1 x 10(-14) mol2 dm-6 at 298K

Question 2

How do you calculate the pH of strong bases?

Answer 2

Find the concentration of OH- ions (some extra calculations may be required)
Divide concentration by 1 x 10(-14) to find a value for Kw
Put this value into -log 10 [H+]
