WebFinal answer. Step 1/4. 1)The process that results in the production of chlorine gas (Cl2) and sodium hydroxide (NaOH) is called the chloralkali process. Explanation: This process involves the electrolysis of a solution of sodium chloride (NaCl) in water (H2O) using a special type of electrolytic cell called a diaphragm cell or a membrane cell. WebJul 20, 2024 · Figure 17.3. 1 Diaphragm or Hooker cell for electrolysis I of brine (schematic). Since chloride ions are removed and hydroxide ions produced by the electrolysis, the electrolyte gradually changes from a solution of sodium chloride to a solution of sodium …
WebDiaphragm cell electrolysis (bipolar) In diaphragm cell electrolysis, an asbestos (or polymer-fiber) diaphragm separates a cathode and an anode, preventing the chlorine forming at the anode from re-mixing with the sodium hydroxide and the hydrogen formed at the cathode.
