In an electrolysis experiment, a cathode of mass 5g is found to weigh 5.01g after a current of 5A flows for 50 seconds. What is the electrochemical equivalent of the deposited substance?
0.00004g/C
0.00002g/C
0.02500g/C
0.05000g/C
0.00001g/C
Correct answer is A
M = Itz
5.01 - 5.00 = 50 x 5 x z
z = 0.00004g/C
