The electrolysis of molten NaCl indeed gives elemental sodium and chlorine gas: $\ce {2NaCl (l) -> 2Na (l) + Cl2 (g)}$ However, in solution (namely aqueous solution such that you are doing the electrolysis on a solution of NaCl in water), the highly reactive Na produced reacts instantly with water to give sodium hydroxide, hence why no solid Na is ever observed. Electrolysis is, also done in the presence of additional salts to aid the redox reactions. The Electrolysis of Aqueous Sodium Chloride The electrolysis of aqueous sodium chloride is the more common example of electrolysis because more than one species can be oxidized and reduced.

during the electrolysis of Sodium Chloride chhlorine gas is produced at the anode and hydrogen gas is produced at the cathose. Electrolysis of sodium chloride is an important process to manufacture many bulk chemicals of commercial utility, like chlorine, sodium hydroxide etc.

Sodium iodide dissolved in the water is also an electrolyte and enables the electrolysis of water.

(i) Electrolysis of aqueous sodium chloride is an important industrial process, since the products are commercially important chlorine, hydrogen, and sodium hydroxide. The electrolysis of sodium chloride solution (brine) and molten sodium chloride.

Gas extraction. What are the products of the electrolysis of aqueous sodium chloride solution (brine)? sodium chloride: colourless gas produced: hydrogen gas (squeeky pop test) pale green gas produced: ... A student conducts an investigation to find out what is produced during the electrolysis of sodium sulfate. Every 2 moles of sodium chloride produce 2 moles of sodium metal and 1 mole of chlorine gas $2NaCl (l) \rightarrow 2Na(s) + Cl_{2} (g)$ Case Study: Electrolysis of … The (–) cathode gas - colourless gas gives a squeaky pop with a lit splint – hydrogen. The diaphragm that separates the two electrodes is a screen of iron gauze, which prevents the explosive reaction that would occur if the products of the electrolysis reaction came in contact. Liquid sodium floats to the top of the melt above the cathode and is drained off into a storage tank. Chlorine gas bubbles out of the melt above the anode.

The diaphragm that separates the two electrodes is a screen of iron gauze, which prevents the explosive reaction that would occur if the products of the electrolysis reaction came in contact. Electrolysis cell for molten sodium chloride: A commercial electrolysis cell for the production of metallic sodium and chlorine gas from molten NaCl. Most chlorine is manufactured by the electrolysis of sodium chloride solutions. Describe how the student could carry out an investigation, and show (using ions) what is given off at each electrode.

Electrolysis cell for molten sodium chloride. Electrolysis of Sodium Chloride.
