JEE Main 2022 Chemistry question
A dilute solution of sulphuric acid is electrolysed using a current of 0.10 A for 2 hours to produce hydrogen and oxygen gas. The total volume of gases produced at STP is . (Nearest integer) [Given : Faraday constant F = 96500 C at STP, molar volume of an ideal gas is 22.7 L ]
Answer: 127
Solution
The charge passed is C. Electrolysis of water gives 1.5 mol of gases (1 mol mol ) for 2F of
