| Found in | Wikipedia, Jan. 27, 2013 (Hydrofluoric acid (HF) is a solution of hydrogen fluoride in water. It is a valued source of fluorine and is a precursor to numerous pharmaceuticals such as fluoxetine (Prozac) and diverse materials such as PTFE (Teflon). Other names: fluoric acid; fluorhydric acid) The emergency response safety and health database, via WWW, Jan. 27, 2013 (Hydrogen fluoride is a colorless fuming liquid below 67°F (19.4°C), or a colorless gas. When hydrogen fluoride is combined with water it is known as hydrofluoric acid, a colorless liquid, which in low concentrations is visually indistinguishable from water. Hydrofluoric acid that is more than 40% hydrogen fluoride fumes in air.) Hydrofluoric acid 70% material safety data sheet, via Hi-Valley Chemical Inc. website, Jan. 27, 2013 (Hydrofluoric acid 70%. Synonyms: Fluorohydric acid; fluoric acid; Hydrogen fluoride solution) Facts about hydrogen fluoride (hydrofluoric acid), via Centers for Disease Control and Prevention website, Jan. 27, 2013 (Hydrogen fluoride is a chemical compound that contains fluorine. It can exist as a colorless gas or as a fuming liquid, or it can be dissolved in water. When hydrogen fluoride is dissolved in water, it may be called hydrofluoric acid.) |
