Concentration at the surface of a solution
« on: December 03, 2011, 11:48:28 PM »


I am required to estimate the concentration at the surface of pentalysine with a 10^-4 M bulk concentration.
Is this information really sufficient to solve this question?I thought I would need the electrostatic potential and/ the charge density to calculate this

I read the word Ā«estimateĀ» in your question.

Is not enough to obtain a relationship between surface and bulk concentration and then solve for 10-4 M?
