They range from those of water at very low concentrations approaching 0% HCl to values for fuming hydrochloric acid at over 40% HCl. [31] [32] [33] Hydrochloric acid as the binary (two-component) mixture of HCl and H 2 O has a constant-boiling azeotrope at 20.2% HCl and 108.6 °C (381.8 K; 227.5 °F).
HO−S(=O) 2 −Cl + NH 2 OH → NH 2 −O−S(=O) 2 −OH + HCl. When heated, hydroxylamine explodes. A detonator can easily explode aqueous solutions concentrated above 80% by weight, and even 50% solution might prove detonable if tested in bulk. [16] [17] In air, the combustion is rapid and complete: 4 NH 2 OH + O 2 → 2 N 2 + 6 H 2 O
A solution of tin(II) chloride containing a little hydrochloric acid is used for the tin-plating of steel, in order to make tin cans. An electric potential is applied, and tin metal is formed at the cathode via electrolysis. Tin(II) chloride is used as a mordant in textile dyeing because it gives brighter colours with some dyes e.g. cochineal ...
In aqueous solution, ammonia deprotonates a small fraction of the water to give ammonium and hydroxide according to the following equilibrium: . NH 3 + H 2 O ⇌ NH + 4 + OH −.. In a 1 M ammonia solution, about 0.42% of the ammonia is converted to ammonium, equivalent to pH = 11.63 because [NH +

The hydrochloride salt, triethylamine hydrochloride (triethylammonium chloride), is a colorless, odorless, and hygroscopic powder, which decomposes when heated to 261 °C. Triethylamine is soluble in water to the extent of 112.4 g/L at 20 °C. [3] It is also miscible in common organic solvents, such as acetone, ethanol, and diethyl ether.
Methylamine has been produced industrially since the 1920s (originally by Commercial Solvents Corporation for dehairing of animal skins). [4] This was made possible by Kazimierz Smoleński [] and his wife Eugenia who discovered amination of alcohols, including methanol, on alumina or kaolin catalyst after WWI, filed two patent applications in 1919 [5] and published an article in 1921.
The compound is a salt with separated hydroxyammonium and nitrate ions. [2] Hydroxylammonium nitrate is unstable because it contains both a reducing agent (hydroxylammonium cation) and an oxidizer (), [3] the situation being analogous to ammonium nitrate.
