Phosphorous Sentence Examples

With water it gave phosphorous acid and a yellow indefinite solid.

Phosphorous acid, P(OH) 3, discovered by Davy in 1812, may be ' obtained by dissolving its anhydride, P 4 0 61 in cold water; by immersing sticks of phosphorus in a solution of copper sulphate contained in a well-closed flask, filtering from the copper sulphide and precipitating the sulphuric acid simultaneously formed by baryta water, and concentrating the solution in vacuo; or by passing chlorine into melted phosphorus covered with water, the first formed phosphorus trichloride being decomposed by the water into phosphorous and hydrochloric acids.

We basically just do not show any deficiencies of phosphorous, potassium, sodium, sulfur, chloride or fluoride.

With chlorine it gives phosphoryl and " metaphosphoryl " chlorides, the action being accompanied with a greenish flame; bromine gives phosphorus pentabromide and pentoxide which interact to give phosphoryl and " metaphosphoryl " bromides; iodine gives phosphorus di-iodide, P 2 I 4, and pentoxide, P 2 0 5; whilst hydrochloric acid gives phosphorus trichloride and phosphorous acid, which interact to form free phosphorus, phosphoric acid and hydrochloric acid.

Phosphorous oxide is very poisonous, and is responsible for the caries set up in the jaws of those employed in the phosphorus industries (see below).

These are typically low in phosphorous which makes them less harmful to the environment.

But plants need more nitrogen, phosphorous and potassium than is readily available in the air and water, which is where a product like Ringer Lawn Restore organic fertilizer comes in.

Additionally, many chemical fertilizers only contain the nutrients nitrogen, phosphorous and potassium.

Vitamin D, along with vitamin A, phosphorous and calcium, work in concert to build strong bones and teeth and prevent tooth decay and osteoporosis.

It is also essential for the absorption of calcium and phosphorous.

Dr. Price believed high amounts of vitamins D and A, along with calcium and phosphorous, gave the people he studied an immunity to tooth decay.

Vitamin D is very important for muscle health because it plays a crucial role in the metabolism of the minerals calcium and phosphorous.

Phosphorous is required for muscular contractions as well.

The phosphorous haloids give the corresponding ethyl haloid.

Some time later Davy, by heating phosphorous acid, obtained a phosphoretted hydrogen which was not spontaneously inflammable.

Water gives hydrochloric and phosphorous acids, with separation of red phosphorus if the water be hot.

The haloid esters of the paraffin alcohols formed by heating the alcohols with the halogen acids are the monohaloid derivatives of the paraffins, and are more conveniently prepared by the action of the phosphorous haloid on the alcohol.

It slowly reacts with cold water to form phosphorous acid; but with hot water it is energetically decomposed, giving much red phosphorus or the suboxide being formed with an explosive evolution of spontaneously inflammable phosphoretted hydrogen; phosphoric acid is also formed.

It is probable, however, that pure phosphorous oxide vapour is odourless, and the odour of phosphorus as ordinarily perceived is that of a mixture of the oxide with ozone.

Exposure to air gives phosphorous and phosphoric acids, and on heating it gives phosphine and phosphoric acid.

The aqueous solution may be boiled without decomposition, but on concentration it yields phosphorous and phosphoric acids.

It is slowly decomposed by water giving hydrofluoric and phosphorous acids, or, in addition, fluorphosphorous acid, HPF4.

Phosphorus trichloride or phosphorous chloride, PC13, discovered by Gay-Lussac and Thenard in 1808, is obtained by passing a slow current of chlorine over heated red phosphorus or through a solution of ordinary phosphorus in carbon disulphide (purifying in the latter case by fractional distillation).

With water it gives sulphur, sulphuretted hydrogen, hydrobromic, phosphorous and phosphoric acids, the sulphur and phosphorous acid being produced by the interaction of the previously formed sulphuretted hydrogen and phosphoric acid.
