Homework Help: Chem

Posted by Kyo on Friday, October 22, 2010 at 6:33pm.

Estimate the equilibrium constant for the weak base (CH3)2NH, if a 1.5910-2 M aqueous solution of (CH3)2NH has a pOH 2.58 (make an exact calculation assuming that initial concentration is not equal to the equilibrium concentration).
(CH3)2NH + H2O = (CH3)2NH2+ + OH-

I know how to calculate it if initial concentraton = equilibrium concentration...but how are you suppose to calculate it if they aren't?
