Question
The preparation of LiOH by the electrolysis of a 35% solution of LiCl using a platinum anode led to a current efficiency of 80%. What weight of LiOH was formed by the passage of 2.5 A for 4825 s?
Options
A.1.92 g
B.2.40 g
C.0.96 g
D.0.672 g
Solution
neq of Li OH = $\frac{Q}{F} \Rightarrow \frac{w}{24} \times 1 = \frac{2.5 \times 4825 \times 0.8}{96500}$
