WebHydrogen fluoride and hydrofluoric acid (collectively referred to as HF) are used in industrial applications and other processes where workplace exposures can occur. Hydrofluoric … Web1. number of carbons (increase in number of carbons, and hence molecular weight, increases BP) 2. Like you said, surface area. (increase in SA results increase in BP) 3. The strength of IMF. So I believe, that because nonane has more number of carbons AND more surface area, that's TWO factors that makes it have higher BP.
WebThe pure gaseous forms are easier to compare boiling points, but the acid forms are more commonly dealt with in chemistry. I'll just assume you meant the pure forms of both; hydrogen chloride and hydrogen fluoride. Hydrogen chloride has a boiling point of 188.10 K and hydrogen fluoride has a boiling point of 292.6 K.

Hexafluorosilicic acid can release hydrogen fluoride (HF) when evaporated, so it has similar risks. …
Hydrofluoric acid is a solution of hydrogen fluoride (HF) in water. Solutions of HF are colourless, acidic and highly corrosive. It is used to make most fluorine-containing compounds; examples include the commonly used pharmaceutical antidepressant medication fluoxetine (Prozac) and the material PTFE (Teflon). … See more Production of organofluorine compounds The principal use of hydrofluoric acid is in organofluorine chemistry. Many organofluorine compounds are prepared using HF as the fluorine source, including Teflon See more In dilute aqueous solution hydrogen fluoride behaves as a weak acid, Infrared spectroscopy has been used to show that, in solution, dissociation is accompanied by formation of the See more In addition to being a highly corrosive liquid, hydrofluoric acid is also a powerful contact poison. Because of the ability of hydrofluoric acid to penetrate tissue, poisoning can occur readily through exposure of skin or eyes, or when inhaled or swallowed. … See more • International Chemical Safety Card 0283 • NIOSH Pocket Guide to Chemical Hazards • CID 14917 from PubChem (HF) See more Hydrofluoric acid was first prepared in 1771, by Carl Wilhelm Scheele. It is now mainly produced by treatment of the mineral fluorite, CaF2, with concentrated sulfuric acid at approximately 265 °C. CaF2 + H2SO4 → 2 HF + CaSO4 The acid is also a … See more Unlike other hydrohalic acids, such as hydrochloric acid, hydrogen fluoride is only a weak acid in dilute aqueous solution.

Hydrofluoric acid is the only hydrohalic acid (such as HCl, HI) that is not a strong acid. HF ionizes in an aqueous solution like other acids: . HF + H 2 O ⇆ H 3 O + + F -. Hydrogen fluoride does actually dissolve fairly freely in water, but the H 3 O + and F - ions are strongly attracted to each …
