1. The problem statement, all variables and given/known data Current passes through a solution of sodium chloride. In 1.00 second, 2.68 x 10^16 Na+ ions arrive at the negative electrode and 3.92 x 10^16 Cl- ions arrive at the positive electrode. What is the current passing between the electrodes? Express your answer in milliamperes to three significant figures. Part B What is the direction of the current? ~away from the negative electrode or ~toward the negative electrode 2. Relevant equations I = Q/t 3. The attempt at a solution the difference between 2.68x10^16 and 3.92x10^16 as a Na+ ion and Cl- ion carry precisely one electric charge each, and the charge of an electron is 1.60 x 10^-19 C I = Q/t I = (1.60 x 10^-19 )/1 I = 1.60 x 10^-19 A = 1.60 x 10^-16 mA am I right? Part B Conventional current was defined early in the history of electrical science as a flow of positive charge, so it would be towards the negative electrode?
