During the electrolysis of copper (II) tetraoxosulphate (VI) solution, an ammeter shows a steady reading of 1A for 30minutes while 6.6 x 104kg of copper is liberated. Calculate the error in the ammeter The electrochemical equivalent of copper is 3.30 x 107kgC1

A.

0.001A

B.

0.011A

C.

0.111A

D.

1A

E.

1.1A

Correct answer is C

m=zIt, I=mzt=6.6×1043.3×107×1800=1.1111error=1.1111-1.0=0.111A.
