5. A monovalent cation (M) has a measured ion mobility of 7.3x10 cm V-51. The viscosity of the solution is 1.00 mPas. a. Calculate the hydrodynamic radius of the ion in nm. (4 marks) b. Calculate the drift speed of the ion in ums when a potential difference of 1.5 V is applied across two electrodes separated by 0.50 cm. (4 marks) 6. A layer of 10.0 g glucose (180 g mol ) is spread uniformly over the bottom of a graduated cylinder and then carefully covered with water. The bottom of the cylinder has an area 3.1 cm. What is the concentration of sucrose in mol L at a position 2.0 cm above the original layer after 24 hours? Assume diffusion is the only transport process, take D = 2.59x10-10 m?s and assume that the layer of water is effectively infinitely deep. (8 marks)Step by Step Solution
