1. A constant direct current of 0.027 A flows through an silver coulometer for a period
of 1 hour. Calculate the weight of silver deposited in the coulometer.
[0.109]
A constant direct current was passed through a solution of copper sulfate, CUSO4, for
1 h, and 0.040 g of copper was deposited. What much was the current passed?

3. A constant current flows for 3.75 h through two electrolytic cells connected in series.
One contains a solution of AgNO3, and the second a solution of CuCl2. During this
time, 2.00 g silver are deposited in the first cell. How many grams
deposited in the second cell?

4. An electrolytic cell containing ZnSO4 solution was connected in series with a cell
containing NaOH solution. When a constant current was passed through the circuit
for set period of time, 418 cm³ (measured at STP) was liberated in the cell containing
NaOH solution. How many grams of Zn would have been deposited in the cell
containing ZnSO4 solution?
