Hydrogen fluoride, a weak acid in aqueous solution that is normally not thought to have any appreciable Brønsted basicity at all, is in fact the strongest Brønsted base in the mixture, protonating to H 2 F + in the same way water protonates to H 3 O + in aqueous acid. It is the fluoronium ion that accounts for fluoroantimonic acid's extreme ...
For example, fluoroantimonic acid, nominally (H 2 FSbF 6), can produce solutions with a H 0 lower than –28, giving it a protonating ability over a billion times greater than 100% sulfuric acid. [5] [6] Fluoroantimonic acid is made by dissolving antimony pentafluoride (SbF 5) in anhydrous hydrogen fluoride (HF).
Fluorine is a principal component of the strongest known charge-neutral acid, fluoroantimonic acid (H 2 FSbF 6). [30] There is evidence for an even stronger acid called fluoroauric acid (H 2 FAuF 6) but it has not proved isolable. [31] In a molecule that is composed of a central atoms and fluorines attached to it, the intermolecular bonding is ...
In order to protect vital inner organs, the body will cut circulation to extremities such as feet, hands, nose, etc. and they eventually freeze. What are symptoms of frostbite? The CDC lists 4 ...
You have all the signs of a cold, plus the following: Fever over 100°F. Chest coughs. Weakness and fatigue. Headaches. ... Muscle or body aches. Headache. New loss of taste or smell. Sore throat.
Fluoroantimonates may be crystallised from a solution of fluoroantimonic acid with some cation. The most common salts are of [SbF 6] −, but salts of [Sb 2 F 11] − and [Sb 4 F 21] − [1] have been isolated in the laboratory. As fluoroantimonic acid and antimony pentafluoride are highly reactive, other routes to fluoroantimonates are ...

Patients with cold agglutinin disease should include good sources of folic acid, such as fresh fruits and vegetables, in their diet. Activities for these individuals should be less strenuous than those for healthy people, particularly for patients with anemia. Jogging in the cold could be very hazardous because of the added windchill factor.
