In an electrolysis experiment, the ammeter records a steady current of 1A. The mass of copper deposited is 0.66g in 30 minutes. Calculate the error in the ammeter reading (Electrochemical equivalent of copper = 0.00033g C(^{-1})).
Explanation
Mass deposited = 21t
I = (frac{m}{2t} = frac{0.66}{33 times 10^{-5} times 30 times 60})
= 1.11A
error = 1.11 – 1
= 0.11A
