Homework Statement
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. What is the current passing between the electrodes? Final answer must be in milliamperes.
Homework Equations
I = Q / Δt
The Attempt at a Solution
2.68*10^16 Na+ (1.6*10^-19 C) = 4.288 ma
3.68*10^16 Cl- (-1.6*10^-19C) = -6.272 ma
4.288 ma + (-6.272 ma) = -1.984 ma
Why is this incorrect?
