Question

Calculate the current (in mA) required to deposit 0.195 g of platinum metal in 5.0 hours from a solution of PtCl₆^2-: (Atomic weight : Pt = 195)

Easy

A

310
B

31
C

21.44
D

5.36

Solution

$\frac{W}{E} = \frac{I \times t}{96500}; \frac{0 .195}{195} \times 4 = \frac{5 \times 60 \times 60 \times I}{96500}$
I = 21.44
