Question
Electrolysis of dil. H2SO4 generates perdisulphuric acid (H2S2O8). Using 75% efficiency, what current needs to be passed to produce the desired product at the rate of 1 mole per hour.
Answer: B
💡 Solution & Explanation
4 2 2 8 2HSO 2e H S O To produce 1 mole/hr of H2S2O8, 2 mole/hr of electrons need to be released (i.e. 2F). Because efficiency is 75% 8 F 3 8 96500 i 60 60 3 i 71amp.
