Question

In a solution of sodium chloride, 2.68×10¹⁶ Na+ ions arrive at the negative electrode and 3.92×10¹⁶ Cl⁻ ions arrive at the positive electrode in 1.00 s. What is the total charge that passes through the solution in this time?

Answer 1

The total charge that passes through the solution in 1.00 s is 10.56 C.

Step-by-step explanation:

To find the total charge that passes through the solution, we need to calculate the charge carried by each ion and then add them together. The charge carried by an ion can be calculated using the formula Q = n * e, where Q is the charge, n is the number of ions, and e is the elementary charge (1.6 x 10^-19 C).

For the Na+ ions, the charge can be calculated as 2.68 x 10^16 * 1.6 x 10^-19 C = 4.288 C. For the Cl- ions, the charge can be calculated as 3.92 x 10^16 * 1.6 x 10^-19 C = 6.272 C. Finally, adding the charges together gives a total charge of 4.288 C + 6.272 C = 10.56 C.
