Find Ka, Kb & Verify Kw Relation

[nemzy]

I know that Kw is equilibrium constant for water..

but what is Ka and Kb? I Is Ka equilibrium constant for acid and Kb equilibrium constant for Kb? If so how can u find those??

For example..here is an equation

Kw = [OH-][H+] = 1e-14

What is the Ka and the Kb?

Someone told me that Kw=Ka*Kb...is that true?

simple answer would be yes, its true. :)

"a" stands for acid and "b" stands for base dissociation.

to find Ka or Kb simply times H2O by Kc, ie Kc*[H2O].
