occurrence and uses of phophoric acid

It is a common method seen in birds, land reptiles, insects, land snails and some land crustaceans. Uric acid is formed from ammonia mostly in the liver and to some extent in the kidneys. The process is highly energy dependant, but is much less toxic than both ammonia and urea and it is..

Every one of us carries a hydrochloric acid manufacturing unit in our body! It is present in the gastric juice of all mammals. In the stomach hydrochloric acid helps to produce pepsin, which is used for the digestion of proteins. It also helps to destroy harmful ..

Nitrogen exists in the free and in the combined form in the atmosphere of the earth. In the free state it occupies about 80% by volume of air. In the combined form, it is present as ammonia and all ammonium compounds, in nitric acid and in all nitrates, nitrites and in all living th..

Occurrence and Uses of Phosphorus - Phosphorus is widely distributed in nature. It does not occur in free state since it can be very easily oxidised. It is usually present in rocks in the combined state as phosphates. The main phosphate rocks are: Phosphorite: Ca 3 (PO 4 ) 2 Flu..

Occurrence and Uses - Silicon is present in nature in the form of silica (SiO 2 ) and silicates. Rocks and clays consist of silicate minerals. Silicon is the second most abundant element (~ 27.2 wt%) on the earth's crust after oxygen {45.5wt%}. Germanium is a trace element (1.5 ..

Silicon is present in nature in the form of silica (SiO 2 ) and silicates. Rocks and clays consist of silicate minerals. Silicon is the second most abundant element (~ 27.2 wt%) on the earth's crust after oxygen {45.5wt%}. Germanium is a trace element (1.5 ppm) and is mainly recovered from flue dus..

. Aluminium is a lightweight metal with a density of 2.7 g cm - 3 . Al can be easily extruded through dies to form various shapes. It is used for making angles used in windows. Aluminium cables are used to transmit electric current. Al alloys are used in airc..

Occurrence of Sulphuric Acid - In the free state, sulphuric acid is found in some of the hot springs. In the combined state, it is found in the form of metal sulphates, such as barium sulphate, calcium sulphate, magnesium sulphate, alum et..

In Free State - Nitric acid is present in small quantities in the atmosphere. But during thundershowers, a large quantity of this acid is produced in the atmosphere. It then comes down as a very dilute solution in rainwater. This nitric acid present in the acid..
