Electrolytic cell electrons from the cathode and deposits on the cathode as sodium metal. NaCl dissolved in water can also be electrolyzed. The anode oxidizes chloride ions (Cl), and Cl gas is produced. However, at the cathode, instead of sodium ions being reduced to sodium metal, water molecules are reduced to hydroxide ions (OH) and hydrogen gas (H). The overall result of the electrolysis is the production of chlorine gas and aqueous sodium hydroxide (NaOH) solution. Commercially, electrolytic cells are used in electrorefining and electrowinning of several non-ferrous metals. Almost all high-purity aluminium, copper, zinc and lead is produced industrially in electrolytic
Electrolytic detector current until the noise just ceases, at which point the detector is in its most sensitive state. It was found that strong atmospheric noise would render it insensitive, requiring that the device be rebiased after each strong burst of static interference. Another form of electrolytic detector, the sealed-point electrolytic detector, which could stand considerable rough usage, was commercially known as the Radioson Detector; it had the cell sealed in a glass envelope. The operation was the same as in the bare-point electrolytic detector, the advantage being that the acid was sealed in, and consequently could not spill or evaporate. Electrolytic
