8. Water Ionization Constant K w = [H + ][OH - ] or K w = [H 3 O + ][OH - ] K w = 1.00 x 10 -14 Memorize this

9. K w Calculations In pure water [H + ] = [OH - ] K w = [H + ][OH - ] = 1.0 x 10 -14 Let [H + ] = x = [OH - ]

10. K w Calculations K w = [H + ][OH - ] = x 2 K w = x 2 =1.0 x 10 -14 Thus x = 1.0 x 10 -7 M [H + ] = x = 1.0 x 10 -7 M
