question

In order to calculate the cationic and anionic mobilities of the potassium (K^+) and chloride ions (Cl^-) in a .05 normal solution at 25°C, the moving boundary technique was used to first determine t_+, the cationic transport number. In a cell having a cross-sectional area of 1 cm^2, a current of .007A was applied for 1 hr. The observed boundary moved 2.56 cm. Given that ^ = 136.0 cm^2 mol^-1 \Omega^-1 for the solution, find \mu_+ and \mu_-, the cationic and anionic mobilities, respectively.
