Ionization of Water

The equilibrium of water can be written as WHAT

H2O (l) + H2O (l) →← H3O (aq) + OH (aq)

What is the equilibrium law

Kw = [ H3O ] [ OH ]

The equilibrium constant for water is designed as WHAT

Kw

at 25°C, neutral water has [H (aq)] = [H3O (aq)] = 1.0×10 ^ -7 mol/L therefore Kw = WHAT

1.0×10 ^ -14 mol/L

of [H3O (aq)] = [OH (aq)], then the solution is WHAT

Neutral

of [H3O (aq)] > [OH (aq)], then the solution is WHAT

Acidic

of [H3O (aq)] < [OH (aq)], then the solution is WHAT

Basic

The number of digits following the decimal place in the pH value is equal to the number of WHAT in the [H3O]
