Water Ionization Constant

Kw = [H+][OH-]

Kw = [H3O+][OH-]

Kw = 1.00 x 10-14

Memorize this

Page 6: Drill: Calculate the pH of  2.0  x  10 -4  M HI

Kw CalculationsIn pure water [H+] = [OH-]

Kw = [H+][OH-]

= 1.0 x 10-14

Let [H+] = x = [OH-]

Page 7: Drill: Calculate the pH of  2.0  x  10 -4  M HI

Kw CalculationsKw = [H+][OH-] = x2

Kw = x2 =1.0 x 10-14

Thus x = 1.0 x 10-7 M

[H+] = x = 1.0 x 10-7 M

Page 8: Drill: Calculate the pH of  2.0  x  10 -4  M HI

pH of Pure Water[H+] = 1.0 x 10-7 M

pH = -log[H+]

pH = -log[1.0 x 10-7]

pH = 7 -log 1

Thus pH = 7.00
