K _w = [H ₃ O ⁺] [OH ^-] = 1.0

10 ^-14 (saa 25 °C)

pH = -logi [H_{3} O^{+}]

oH = -logi [OH ^∙]

[H ₃ O ⁺] = 10 ^-pH

[^{OH -}] = 10 ^—poh

pH + poH = p K _w = 14.00 saa 25 °C

K_{a} = \frac{[H_{3} O^{+}] [A^{-}]}{[HA]}

Asilimia ionization = \frac{{[H_{3} O^{+}]}_{eq}}{{[HA]}_{0}} \times 100

p K _a = -logi K _a

p K _b = -logi K _b
