How you find pH with Kb? What units do I need and what is the formula?

Kb's formula is [BH+][OH-]/[B]

From this formula you can calculate OH-, and if you remember the concentration of H+ is equal to Kw/[OH-]. Once you find the concentration of H+, you can then use that to calculate the pH.

Hope this helps!
