Document Summary

Please turn in this front page with your signature: Problem #2. (20 points) double layer & electrokinetics (a) (10 points) high salt concentrations can effectively screen charge in physiological situations. Human blood has a nacl content of about 0. 150 m. calculate the debye screening length ( ) in 0. 150 molar solutions of (i) nacl, (ii) cacl2. Use the gauss law to calculate the solution phase charge density per unit area if the potential at the surface (x = 0) is held at 0. Hint: as x -> , d /dx -> 0. Problem #3 (20 points) electrokinetics (a) (5 points) draw the velocity profile for pressure driven flow and electro osmotic flow inside an electrophoretic separation chamber. Which one is better and why? (b) (10 pints) protein a & b are to be separated and the protein a has a mobility ( i) of. 1. 000x10-8 m2/v s and the protein b has a mobility of 1. 010x10-8 m2/v s.
