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?

yes to all, therefore the concentration of each is to the -7.
