Question 5

What is the approximate strength of current that will deposit 0.5 g of silver on a spoon in 7.5 minutes? E.C.E. of silver Description: E:\Gate\SSC-JE Electrical - Part 1\10_Chemical-Effects-of-Electric-Current-final_files\image161.png

Question 6

Silver and copper voltameters are connected in parallel to a 12 V battery of negligible internal resistance. In 30 minutes, 1 g of silver and 1.8 g of copper are deposited. At what rate, the battery is delivering energy? Given E.C.E. of Description: E:\Gate\SSC-JE Electrical - Part 1\10_Chemical-Effects-of-Electric-Current-final_files\image071.png and Description: E:\Gate\SSC-JE Electrical - Part 1\10_Chemical-Effects-of-Electric-Current-final_files\image072.png

Question 7

A Description: E:\Gate\SSC-JE Electrical - Part 1\10_Chemical-Effects-of-Electric-Current-final_files\image017.png resistor and a silver voltameter of resistance Description: E:\Gate\SSC-JE Electrical - Part 1\10_Chemical-Effects-of-Electric-Current-final_files\image044.png are connected in series across a cell. How will the rate of deposition of silver be effected if a resistance of Description: E:\Gate\SSC-JE Electrical - Part 1\10_Chemical-Effects-of-Electric-Current-final_files\image044.png is connected in parallel with the voltameter?

Question 8

One ampere current flows for one minute through a silver voltameter. It deposits 0.067 g of silver on the cathode. What is the E.C.E. of silver?

Question 9

A battery of accumulators of e.m.f. 50 V and internal resistance Description: E:\Gate\SSC-JE Electrical - Part 1\10_Chemical-Effects-of-Electric-Current-final_files\image044.png is charged on a 100 V direct current mains. What series resistance will be required to give a charging current of 2 A?

Question 10

Two electrolytic cells containing solutions of silver and gold salts respectively are connected in series to a d.c. supply. It is found that by the time 8.3 g of silver (atomic weight 108, valency 1) is deposited on one cell, 5.05 g of gold (atomic weight 197, valency 3) is deposited on another. The amount of charge that has flown during this time is
