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