calculating H30+ and OH- in .22M KOH
« on: May 23, 2006, 09:46:47 AM »
Hi guys, I am workign on a problem and I am experiencing some confusion.
Heres what I know

 calculating H30+ and OH- in .22M KOH

I can use the Ionization constant formula to figure out my Kb
I use my Kb in my  Kw formula to figure out the concentrations of the OH and H3O Ions

I think this is true but it says in my book that the procedure is different if the base is a weak base because it will no ionize 100% so the M relationships due to stoicheometry won't be the same.

Can anyone tell me how to do this problem?

No need for Kb, assume all KOH is dissociated.

Calculation of pH of strong acid or base.

if there was a Kb needed how would I go about using it?
