Potassium chlorate is prepared by the
electrolysis of KCl in basic solution
6OH⁻ + Cl⁻ ClO₃⁻ + 3H₂O + 6e⁻
If only 60% of the current is utilized in the
reaction, the time (rounded to the nearest hour)
required to produce 10 g of KClO₃ using a
current of 2 A is_________.
(Given : F = 96,500 C mol^–1; molar mass of
KCIO₃ = 122 g mol^–1)
