Titanium Dioxide ... Properties and Questions | Chemical Safety Facts. 76. Sodium hydroxide (NaOH) Sodium reacts with water more vigorously than lithium and less vigorously than potassium. When Chlorine gas enters or comes in contact with human body, it reacts with mucous membrane. Sodium Hydroxide Read more: Understanding Risk and Hazard When it Comes to Chemicals. Many of the compounds that sodium forms are water-soluble, meaning they dissolve in water. 77. 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 useful chemicals and chemical processes involve hydroxides or hydroxide ions. There are more than 2,000 naturally-occurring organic compounds of Chlorine. When sodium reacts with water it produces sodium hydroxide and hydrogen gas. At room temperature, pure sodium hydroxide (NaOH) is a white, odorless solid. Lye as a chemical has many uses. Lye is soluble in water and is a good conductor of electricity. Its chemical formula is NaOH, and it is known to be corrosive as well as soluble in water, alcohol, and glycerin. The salt easily dissolves in water. List of hydroxides. 78. Its chemical name is sodium hydroxide. Its dissolution in water is endothermic, which means it takes some heat energy away from the water. Chlorine is so highly electronegative that it reacts with almost every element to form chlorides. It is the sixth most abundant element on Earth, comprising about 2.6% of the earth's crust. Sodium hydroxide, a white crystalline substance, is also known in other terms such as lye, caustic soda, white caustic, soda lye, and sodium hydrate. Its white powder destroys waste by its ability to eat organic material. Sodium floats on water, because its density is lower than water’s. Uses of hydroxides. Most inorganic hydroxide salts do not dissolve in water. Remarkable Chlorine Element Facts: 76-80 | Fun Facts about Chlorine. It is used in the making of hard soap and textiles, in tanning LEATHER, in refining petroleum, and in the canning industry. 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). Its Atomic Number is 11 which means that it has 11 protons in its nucleus. Explosions occur when the heat generated by the sodium-water reaction ignites the … Sodium hydroxide is an alkaline corrosive. 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. 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. Sodium hydroxide is the main ingredient in household products such as liquid drain cleaners. Sodium is a metal which is considered to be highly reactive. It reacts with moisture from the air and may generate heat as it dissolves. 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. Sodium will float on water, but it will also react violently when coming into contact with water. 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 has a waxy, silvery sheen and is very light weight. It is soft and can be cut with a dull knife at room temperature. It is the most abundant alkali metal.
