[SOLVED] Current in a solution of NaCl ions. 1. The problem statement, all variables and given/known data Current passes through a solution of sodium chloride. In 1.00 second, 2.68*10^16 Na+ ions arrive at the negative electrode and 3.92*10^16 Cl- ions arrive at the positive electrode. A) What is the current passing between the electrodes? B) What is the direction of the current? (Toward, or away from the negative electrode) I haven't encountered a problem like this before in my Physics course, and I haven't taken Chem in a while. For part A, could I be given a hint on what equation to use? For part B, how would I figure this out on my own (Without being told the answer)? In theory, it'd be going towards the negative electrode, as we consider electricity to go from positive, to negative. From what I understand, we basically have saltwater or saltliquid of somesort... which is a mix of Na+ and Cl-... when we pass current through this, the Cl- will shoot towards the positive electrode, and the Na+ towards the negative. But how do I use these facts to calculate a current?
