A saturated solution of the gas, in water, is a colourless, oily, strongly fuming liquid which after a time decomposes, with separation of metaboric acid, leaving hydrofluoboric acid HF BF3 in solution.
The residue is dissolved in alcohol and to the cold saturated solution a cold alcoholic solution of picric acid is added.
It appears, therefore, that liquid oxygen is by far the most strongly paramagnetic liquid known, its susceptibility being more than four times greater than that of a saturated solution of ferric chloride.
According to Michel and Kraft, one litre of cold saturated solution of tin crystals weighs 1827 grammes and contains 1333 grammes of SnCl 2.
It is fairly soluble in water; too parts at o° dissolving 13.3 parts of the salt, and about 30 parts at 20°; the most saturated solution contains 327.4 parts of the salt in too of water; this solution boils at 114.1°.
