Ammonia readily dissolves in water. In an aqueous solution, it can be expelled by boiling. The aqueous solution of ammonia is basic, and may be described as aqueous ammonia or ammonium hydroxide. [30] The maximum concentration of ammonia in water (a saturated solution) has a specific gravity of 0.880 and is often known as '.880 ammonia'. [31]
Treatment of 1000 tons of copper ore yields approximately one kilogram (2.2 pounds) of tellurium. [36] The anode sludges contain the selenides and tellurides of the noble metals in compounds with the formula M 2 Se or M 2 Te (M = Cu, Ag, Au). At temperatures of 500 °C the anode sludges are roasted with sodium carbonate under air.
Hyperbaric medicine includes hyperbaric oxygen treatment, which is the medical use of oxygen at greater than atmospheric pressure to increase the availability of oxygen in the body; [8] and therapeutic recompression, which involves increasing the ambient pressure on a person, usually a diver, to treat decompression sickness or an air embolism by reducing the volume and more rapidly eliminating ...
For a 70 kg adult, at the lower 5 g/kg limit, 350 g could produce death in humans. For comparison's sake, the LD 50 of salt is reported to be 3.75 g/kg in rats according to the Merck Index . According to the Agency for Toxic Substances and Disease Registry , "The minimal lethal dose of ingested boron (as boric acid) was reported to be 2–3 g ...
Upon treatment with a standard base, it converts to metal acetate and water. With strong bases (e.g., organolithium reagents), it can be doubly deprotonated to give LiCH 2 COOLi. Reduction of acetic acid gives ethanol. The OH group is the main site of reaction, as illustrated by the conversion of acetic acid to acetyl chloride.
Aniline (from Portuguese anil ' indigo shrub ', and -ine indicating a derived substance) [6] is an organic compound with the formula C 6 H 5 NH 2.Consisting of a phenyl group (−C 6 H 5) attached to an amino group (−NH 2), aniline is the simplest aromatic amine.
It is an ionic compound strongly insoluble in water. However, it dissolves in hydrofluoric acid, in which it forms an adduct with water, GaF 3 ·3H 2 O. Attempting to dehydrate this adduct forms GaF 2 OH·nH 2 O. The adduct reacts with ammonia to form GaF 3 ·3NH 3, which can then be heated to form anhydrous GaF 3. [30]: 128–129
