61 25 g of kClO Box on heating gives enough O_{2} to react completely with H_{2} produced by the action of the Al on excess of NaOH with 75% yield
2KClO3 = 2KCl+3O 2
6H 2 O+2NBOH+2AI = 2NalAl(OH) 4 ]+3H 2 2H 2 +O 2 2H 2 O
The weight of Al needed is
(in gram) (Molar mass in 0mo * l ^ - 1 of KClO 3 -122.5 H 2 -2 O 2 -32.Al-27)
