What type of reaction show in electro lysis of water what is the moleratio of H2 and O2 in it.Q.2 |
|
Answer» In the electrolysis of water (a) the gas is collected at cathode is Hydrogen , H₂And the gas collected at anode is oxygen ,O₂ (b) first of all we should we reaction between Hydrogen and oxygen to form water :- 2H₂ + O₂ ⇔ 2H₂O you can see that, 2moles of H₂ and 1 mole of O₂ react to form 2moles of H₂O we can also say that , if we break 2moles of water (using electrolysis ) , we gain 2hole of H₂ and one mole of O₂ Here, P, T, are constant , So, Volume is directly proportional to number of moles ∴ if we break 2V of water, we get 2V of H₂ and 1V of O₂ .That's why the volume is collected at one electrode is double than other . |
