How many faradays are required to reduce 0.25
WebHow many faraday of electricity is required to produce 0.25 mole of copper? Options A) 1.00F B) 0.01F C) 0.05F D) 0.50F Related Lesson: Quantitative Aspects of Electrolysis Electrochemistry The correct answer is D. Explanation: Cu → Cu 2+ + 2e 1mole Cu requires 2f 0.25 mole Cu requires x x = 0.25x2/1 = 0.50f Web1 faraday = 96500 coulombs. Now If we reduce MnO4- to Mn+2 we will require a total of 5 electrons for each molecule of MnO4- . So for one molecule number of electrons needed = 5 For one mole of molecules number of electrons needed = 5 × 6.022 ×10^23 ~ 3.011×10^24 electrons Now charge on one electron = 1.6×10^-19
