WebElectrolysis of dilute aqueous NaCl solution was carried out by passing 10 milli ampere current. The time required to liberate 0.01 mol of H$$_2$$ gas at the cathode is (1 … WebSolutions. ( 1) During the electrolysis of concentrated aqueous sodium chloride, positively charged hydrogen ions are attracted to the negative cathode where they are reduced to form hydrogen gas. At the positive anode, the C l− ions are oxidized to form chlorine gas. The ions that remain in solution are N a+ ions and the OH − ions.

WebThe chloralkali process (also chlor-alkali and chlor alkali) is an industrial process for the electrolysis of sodium chloride (NaCl) solutions. It is the technology used to produce … WebElectrolysis of sodium chloride solution (brine) As shown above, the electrolysis of sodium ...
WebApr 20, 2015 · With electrolysis, the products will be sodium metal and chlorine gas. In an aqueous solution, the sodium chloride still moves the charges from one electrode to the other, but the potential for electrolysis of water is less than $\ce{Na^+}$ or $\ce{Cl^-}$. So the products of a solution of sodium chloride is hydrogen gas and oxygen gas. WebDec 23, 2024 · The electrolysis of aqueous NaCl can be carried out by a similar arrangement as that for electrolysis of molten NaCl. Due to the involvement of water, the reactions taking place at electrodes are different. Reduction half-reaction at the cathode: Na + (l) + 1 e – → Na (s) (reduction) and. 2H 2 O + 2e – → H 2 ↑ + 2OH – (aq)
