Uses of hydroxides. Sodium hydroxide is an alkaline corrosive. Sodium has a waxy, silvery sheen and is very light weight. Sodium hydroxide, a white crystalline substance, is also known in other terms such as lye, caustic soda, white caustic, soda lye, and sodium hydrate. Explosions occur when the heat generated by the sodium-water reaction ignites the … 78. It also reacts vigorously with water – violently if more than a small amount of sodium meets water (see video on left) – to produce sodium hydroxide and hydrogen gas. The chemical may sound unfamiliar to you but it can be found in household products such as oven cleaners and drain cleaners. The salt easily dissolves in water. It is used in the making of hard soap and textiles, in tanning LEATHER, in refining petroleum, and in the canning industry. Its chemical formula is NaOH, and it is known to be corrosive as well as soluble in water, alcohol, and glycerin. Remarkable Chlorine Element Facts: 76-80 | Fun Facts about Chlorine. There are more than 2,000 naturally-occurring organic compounds of Chlorine. Sodium Hydroxide Read more: Understanding Risk and Hazard When it Comes to Chemicals. Its white powder destroys waste by its ability to eat organic material. Many useful chemicals and chemical processes involve hydroxides or hydroxide ions. Sodium reacts with water more vigorously than lithium and less vigorously than potassium. 77. Its Atomic Number is 11 which means that it has 11 protons in its nucleus. Lye is soluble in water and is a good conductor of electricity. Titanium Dioxide ... Properties and Questions | Chemical Safety Facts. Sodium hydroxide (NaOH) 76. It is soft and can be cut with a dull knife at room temperature. Chlorine is so highly electronegative that it reacts with almost every element to form chlorides. Sodium chloride melts at 1,474 ° F (801 ° C), boils at 2,670 ° F (1,465 ° C), has a density of 2.16 g/cm 3 (at 25 ° C), and conducts electricity when dissolved or in the molten state. When sodium reacts with water it produces sodium hydroxide and hydrogen gas. Sodium hydroxide is the main ingredient in household products such as liquid drain cleaners. List of hydroxides. Sodium floats on water, because its density is lower than water’s. Its dissolution in water is endothermic, which means it takes some heat energy away from the water. Its chemical name is sodium hydroxide. Sodium hydroxide is used in factories as an alkali, potassium hydroxide is used in farming, and iron hydroxide have been used as low grade brown iron ore. Many of the compounds that sodium forms are water-soluble, meaning they dissolve in water. Most inorganic hydroxide salts do not dissolve in water. At room temperature, pure sodium hydroxide (NaOH) is a white, odorless solid. Lye as a chemical has many uses. Sodium is most famous for its many useful compounds such as table salt (NaCl), sodium nitrate (Na 2 CO 3), and baking soda (NaHCO 3). It is the sixth most abundant element on Earth, comprising about 2.6% of the earth's crust. Cl ₂ (g) + 2 NaOH (aq) = NaOCl (aq) + NaCl (aq) + H ₂ O (l) Most commonly, solutions are 12% NaOCl with a specific gravity of 1.2, demonstrating that sodium hypochlorite solutions are not chemically 100% NaOCl, but rather NaOCl diluted in water, with salt, and some sodium hydroxide left from the manufacturing process. It reacts with moisture from the air and may generate heat as it dissolves. Although it's too reactive to occur in pure elemental form, it is found in many minerals, including halite, cryolite, soda niter, zeolite, amphibole, and sodalite. Sodium is a metal which is considered to be highly reactive. It is the most abundant alkali metal. Sodium will float on water, but it will also react violently when coming into contact with water. When Chlorine gas enters or comes in contact with human body, it reacts with mucous membrane.
