Acid-Base Equilibria

Ionization of Water H 2 O (l)  H + (aq) + OH - (aq) 2 H 2 O (l)  H 3 O + (aq) + OH - (aq)

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

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

K w Calculations K w = [H + ][OH - ] = x 2 K w = x 2 =1.0 x Thus x = 1.0 x M [H + ] = x = 1.0 x M

pH of Pure Water [H + ] = 1.0 x M pH = -log[H + ] pH = -log[1.0 x ] pH = 7 -log 1 Thus pH = 7.00
