Sodium hydroxide - McGill School Of Computer Science

Sodium hydroxide (Na OH), also known as lye or caustic soda, is a caustic metallic base. An alkali, caustic soda is widely used in many industries, mostly as a strong chemical base in the manufacture of pulp and paper, textiles, drinking water, and detergents. Worldwide production in 1998 was around 45 million tonnes. Sodium hydroxide is also the most common base used in chemical laboratories

Hydrogen production by alkaline water electrolysis

Nickel (Ni) is a popular choice due to its low cost, good activity, and easy availability. 48 To enhance conductivity, the electrolyte used in the cell should consist of high-mobility ions. 49 Potassium hydroxide (KOH) is normally used in alkaline water electrolysis, thus avoiding the corrosion problems caused by acid electrolytes. 42 KOH is

The membrane. The membrane is made from a polymer which only allows positive ions to pass through it. That means that the only the sodium ions from the sodium chloride solution can pass through the membrane - and not the chloride ions. The advantage of this is that the sodium hydroxide solution being formed in the right-hand compartment never gets contaminated with any sodium chloride solution.

Chloralkali process - Wikipedia

The chloralkali process (also chlor-alkali and chlor alkali) is an industrial process for the electrolysis of sodium chloride solutions. It is the technology used to produce chlorine and sodium hydroxide (lye/caustic soda), which are commodity chemicals required by industry. 35 million tons of chlorine were prepared by this process in 1987. Industrial scale production began in 1892.
