Sodium metabisulfite or sodium pyrosulfite (IUPAC spelling; Br. E. sodium metabisulphite or sodium pyrosulphite) is an inorganic compound of chemical formula Na 2 S 2 O 5. The substance is sometimes referred to as disodium metabisulfite. It is used as a disinfectant, antioxidant, and preservative agent. [2]
Ethanol is the oldest known sedative, used as an oral general anesthetic during surgery in ancient Mesopotamia and in medieval times. [16] [17] Mild intoxication starts at a blood alcohol concentration of 0.03-0.05 % and induces anesthetic coma at 0.4%. [25] However, this use carried the high risk of deadly alcohol intoxication and pulmonary ...
Poly ( methyl methacrylate) ( PMMA) is the synthetic polymer derived from methyl methacrylate. It is used as an engineering plastic, and it is a transparent thermoplastic. PMMA is also known as acrylic, acrylic glass, as well as by the trade names and brands Crylux, Hesalite, Plexiglas, Acrylite, Lucite, and Perspex, among several others ( see ...
Phenol red exists as a red crystal that is stable in air. Its solubility is 0.77 grams per liter (g/L) in water and 2.9 g/L in ethanol. [1] It is a weak acid with p Ka = 8.00 at 20 °C (68 °F). A solution of phenol red is used as a pH indicator, often in cell culture.
Polypropylene ( PP ), also known as polypropene, is a thermoplastic polymer used in a wide variety of applications. It is produced via chain-growth polymerization from the monomer propylene . Polypropylene belongs to the group of polyolefins and is partially crystalline and non-polar.
Chemical safety refers to safety issues surrounding the use, production, transport and handling of chemicals at large or small manufacturing facilities, laboratories, non-chemical sites that use manufactured chemicals for their business, or homes during everyday activities. While there is some overlap, it is therefore different from process ...
