During electrolysis an aqueous solution of a salt of metal M. A current of 2.0A was passed for 32min 10 seconds. The mass of metal M deposited was 2.24g.
(i) Calculate the quantity of charge needed to deposit one mole
(ii) Calculate the charge carried on the ion.
(i) Calculate the quantity of charge needed to deposit one mole.
(ii) Calculate the charge carried on the ion
Step I:
Using the equation Q= It to calculate for the quantity of electricity.
Substituting values,
Q =   2.0x [(32 x   +10]s
=2.0x  
=  
Step II:
IF 3860C deposited 2.24g
xC would deposit 112g
x = 112 x /=C
