(Chlorine). To keep the hydrogen gas and chlorine from reacting together they are separated by a cation-permeable membrane which allows Na+ to circulate maintaining electric neutrality (McMurry and Fay 793). Na+ is not included in the above equation because it is a spectator ion whose "job" is to transfer an electric current. The H2(g) and Cl2(g) are piped away where the chlorine is liquefied for shipping and storage while the H2(g) usually burned to evaporate the water from the sodium hydroxide solution (Chlorine). .

Early soap makers used tallow or other fats for soap. While tallow is still used even in commercial soap production, vegetable fats are also used. The different kinds of fat used depend on the desired final characteristics of the soap. For instance, if the soap is to moisturize, the fat used may be an unsaturated vegetable oil containing vitamin F. The essential fatty acids in vitamin F are linoleic acid, linolenic acid, and arachidonic acid (Cavitch 225). To the skin these bring a healthy, youthful appearance and the hair appears shinier and healthier when in good supply (Vitamins). The texture of soaps made with unsaturated fats is more fluid that those made with saturated fats. This is because the hydrocarbon chain of unsaturated fats have a bend in them located at the double bond. This lessens the cohesion of fat particles making them liquid at room temperature. The bend in the unsaturated fat will also interfere with the reaction between the fatty acids and sodium hydroxide slowing the reaction speed. .

Soap is made from the reaction between a neutral fatty acid and an alkali base. The three far left carbons along with the hydrogen bonded to them make up glycerol. Connecting to the glycerol is three hydrocarbon chains. These are fatty acids and what will react with the strong base (Cavitch 234).
The main reactions involving sodium hydroxide that produce soap are as follows:.
Sodium compounds are important to the paper, glass, soap, textile, petroleum, chemical, and metal industries. Generally soap is a sodium salt of certain fatty acids. ... In the reaction with alcohol you can use brick sodium, molten sodium, or sodium dispersed in hydrocarbons. ... Sodium hydroxide, NaOH, is also commonly known as caustic soda. ... Most sodium hydroxide is produced by the electrolytic cells. ...
Today I"m going to explain background information on sodium and common compounds formed with sodium. The history of sodium began a long time ago, in 1807, when it was isolated by Sir Humphry Davy by electrolysis of solid sodium hydroxide It is the fourth most abundant element on earth, compromising about 2.6% of the earths crust. ... Sodium hydroxide is used in the manufacture of paper, soap, rayon, in oil refining, and in the textile and rubber industries. Sodium tetraborate is known as borax, and sodium fluoride is used as an antibiotic, rat poison and in ceramics Trona is the o...
Sodium has an Atomic Number of 11. ... He discovered Sodium in England. ... Sodium floats on water that decomposes it to evolve hydrogen and form hydroxide. Sodium is also used in glass, soap, paper, textile, chemicals, petroleum, street lights, and batteries .Sodium in its liquid form can sometimes be used to cool nuclear reactors. ... Sodium is prepared by electrolysis of completely dry fused sodium chloride. ...
Milk of magnesia (magnesium hydroxide), which is used as an antacid, is a base; lye (sodium hydroxide), which is used in the manufacture of soap, is another familiar example of base. ... For example, sodium hydroxide contains sodium ions and hydroxide ions. When sodium metal is placed in water, sodium hydroxide is formed and hydrogen gas is released. ... Wet soap is also slippery because of the presence of a base. 3. ... Sodium hydroxide is used in the manufacture of soap, rayon, and paper. ...
Chlorine, hydrogen and sodium hydroxide are used as source materials for various other widely used compounds. The world requires these chemicals in large quantities - 39 million tonnes of chlorine, 36 million tonnes of hydrogen and 41 million tonnes of sodium hydroxide per year. ... Below shows the dot-cross diagram for the formation of sodium chloride: Diagram 1: Formation of sodium chloride To convert sodium chloride into hydrogen, chlorine and sodium hydroxide, we must electrolyse sodium chloride. ... Graph 1 on the following page shows the annual production of chlorine, so...
