Current passes through a solution of sodium chloride. In 1.00 second, 2.68×1016Na+ ions arrive at the negative electrode and 3.92×1016Cl− ions arrive at the positive electrode. Part A What is the current passing between the electrodes?

Answer : The current passing between the electrodes is,

Explanation :

First we have to calculate the charge of sodium ion.

where,

q = charge of sodium ion

n = number of sodium ion =

e = charge on electron =

Now put all the given values in the above formula, we get:

Now we have to calculate the charge of chlorine ion.

where,

q' = charge of chlorine ion

n = number of chlorine ion =

e = charge on electron =

Now put all the given values in the above formula, we get:

Now we have to calculate the current passing between the electrodes.

Thus, the current passing between the electrodes is,
