- The reaction is in the following: Cathode → 2H2O + 2e- → 2OH- + H2 Anode → 2H2O → 4H+ + O2 + 4e-了解详细信息：The reaction is in the following: Cathode → 2H2O + 2e- → 2OH- + H2 Anode → 2H2O → 4H+ + O2 + 4e-www.markedbyteachers.com/gcse/science/the-elec…
In a hydrogen oxygen fuel cell, electricity is produced. In this process H 2 (g) is oxidised at anode and O 2 (g) reduced at cathode. Given : Cathode: O 2 (g) + 2 H 2 O (l) + 4 e − → 4 O H − (a q) Anode : H 2 (g) + 2 O H − (a q) → 2 H 2 O (l) + 2 e − 4.48 L of H 2 at 1 atm and 273 K is oxidised in 9650 sec. The mass of water ...
www.toppr.com/ask/question/in-the-electrolysis-of-…When Na2SO4 dissociates in water, it forms Na+ and SO4(2-) ions. At the anode, oxidation reactions occur, which involves the loss of electrons. At the cathode, reduction reactions take place, where electrons are gained. The possible anode reactions are the processes that involve the production of electrons.

www.markedbyteachers.com/gcse/science/the-elec…The three aqueous solutions (NaBr, PbI2, Na2SO4) undergo electrolysis to yield different half-reactions at the anode and cathode. In the electrolysis of aqueous NaBr, the anode reaction is 2Br- -> Br2 + 2e-, while the cathode reaction is 2H2O + 2e- -> H2 + 2OH-.
