Potassium chlorate is prepared by electrolysis of KCl in basic solution as shown by following equation.
6OH$-$ + Cl$-$ $\to$ ClO3$-$ + 3H2O + 6e$-$
A current of xA has to be passed for 10h to produce 10.0g of potassium chlorate. The value of x is ____________. (Nearest integer)
(Molar mass of KClO3 = 122.6 g mol$-$1, F = 96500 C)
Answer (integer)
1
Solution
$W = {E \over F} \times I \times t$<br><br>$10 = {{122.6} \over {96500 \times 6}} \times x \times 10 \times 3600$<br><br>$x = 1.311$<br><br>Ans. (1)
