chlorous's Usage Examples:

Several oxy-acids of chlorine are known, namely, hypochlorous acid, HC10, chlorous acid, HC10 2 (in the form of its salts), chloric acid, HC10 3, and perchloric acid, HC10 4.

Those elements which are disengaged at the negative pole are termed electro-positive, or positive, or basylous elements, whilst those disengaged at the positive pole are termed electro-negative, or negative, or chlorous elements.

This is illustrated in the four oxyacids of chlorine, HC10, HC10 2, HC10 3, HC10 4, which have the names hypochlorous, chlorous, chloric and perchloric acids.

Balard discovered chlorine monoxide in 1834, investigating its properties and reactions; and his observations on hypochlorous acid and hypochlorites led him to conclude that " bleaching-powder " or " chloride of lime " was a compound or mixture in equimolecular proportions of calcium chloride and hypochlorite, with a little calcium hydrate.

They combine with hypochlorous acid to form chlorhydrins; and are easily soluble in concentrated sulphuric acid, giving rise to sulphuric acid esters; consequently if the solution be boiled with water, the alcohol from which the olefine was in the first place derived is regenerated.

The co-chlor compound results when, (3-phenyl-a-chlorlactic acid (from hypochlorous acid and cinnamic acid) is heated with water; it has a hyacinthine odour and yields phenylacetaldehyde when heated with water.

One of the most important derivatives of hypochlorous acid is bleaching powder.

Examples of mixed anhydrides are C10 2 and N02, which give chlorous and chloric acid, and nitrous and nitric acid: 2C102+ H20HC102+HC103, 2N02+H20HN02+HN03; and of mixed salts Pb203 and Pb304, which may be regarded as lead metaand ortho-plumbate: Pb0 Pb02, 2PbO Pb02.
