H 2 g and O 2 g , can be produced by the electrolysis of water. What total volume i n L of O 2 and H 2 are produced at STP when a current of 30 A is passed through a K 2 S O 4 a q solution for 193 min.?

Step-by-step solution

Total current = 30 × 193 × 60 96500 c u r r e n t = 18 5 F 2 e ⊝ + 2 H 2 O → H 2 + e ⊝ 18 5 × 1 2 m o l e 2 H 2 O → O 2 + 4 H ⊕ + 4 e ⊝ ⇒ 18 5 × 1 4 mole Total volume = 18 5 1 2 + 1 4 × 22.4 l t = 18 5 × 3 4 × 22.4 l t = 18 × 3 × 5.6 5 = 18 × 16.8 5 = 302.4 5 = 60.48 l i t r e
