The same quantity of electricity is passed through one molar solution of H2SO4 and one molar solutio — Electrochemistry Chemistry Question
Question
The same quantity of electricity is passed through one molar solution of H2SO4 and one molar solution of HCl. The amount of hydrogen evolved from H2SO4 as compared to that from HCl is
Answer: A
💡 Solution & Explanation
By Faraday's laws, passing the same quantity of charge produces the same number of equivalents of a substance. Since hydrogen gas is produced at the cathode in both cases and has a constant equivalent weight, the amount evolved is the same. Therefore, correct answer is A.
