ASSIGNMENT 1 1. How long must a current of 20.0A be passed through molten CaCl2 to produce 15.0g of calcium? 2. Water is electrolyzed by passing a current through dilute sodium sulfate solution. The reaction are cathode: 2H+ + 2e → Hz anode: H,0 10, + 2H+ +e What volume of gas will be liberated at each electrode if a current of 2.00A passes for 40,0 minutes at STP? 3. A silver coulometer is employed as an accurate means of measuring current flow, using the change in weight of silver electrode. This reaction is Ag+ + e - Ag If a silver electrode gains 0.3482g in weight over a period of 4250s, what is the average current flowing during this time?
