CarBon Di-Oxide

Carbon dioxide gas is colourless and odourless gas or extremely cold liquid under pressure or refrigeration. It will not burn. Carbon dioxide is a COMPRESSED GAS. It Can displace oxygen in air, it may accumulate in low areas and is a confined space hazard. Carbon dioxide is a very mild central nervous system depressant. Very high concentrations may cause headache, nausea, dizziness, sweating, restlessness and disorientation. Liquefied gas may cause frostbite.


Where do you find carbon dioxide gas?

CO2 gas is used for the carbonation of beverages; for pH control; as a chemical intermediate; in chemical processing; as a food preservative; as an inert "blanket"; and in enhanced oil and gas recovery. Liquid CO2 is used as a refrigerant; for low temperature testing of aviation, missile and electronic components; as a fire-extinguishing agent; for stimulation of oil and gas wells and for controlling temperature in chemical reactions. CO2 gas is a by-product of carbonaceous fuel combustion; is found in naturally occurring gases; is a product of animal and human metabolism, and is found naturally in the atmosphere (about 0.035%).


What should I know about the composition and purity of carbon dioxide gas?

Depending on temperature and pressure, carbon dioxide (CO2) can exist as a solid, liquid or a gas. This review is for CO2 gas which is shipped or stored in high pressure cylinders as a liquid under its own vapour pressure of 5729 kPa at 20 deg C, in insulated containers as a refrigerated liquid, or is made and used on-site. May contain nitrogen, oxygen, argon, hydrogen, carbon monoxide, hydrogen sulfide and amines as impurities, depending on source.


What are some synonyms for carbon dioxide gas?

Carbon dioxide gas is also known as carbonic acid anhydride, carbonic acid gas, carbonic anhydride, carbon oxide, CO2, liquefied carbon dioxide, refrigerated carbon dioxide, anhydride carbonique, and carbon dioxide liquid.


With so many names for carbon dioxide gas, is there a unique identifier for this chemical?

Its CAS Registry Number is 124-38-9. This number is assigned by the Chemical Abstracts Service (CAS) in the United States and is used as a unique identifier number world-wide.

Organic fertiliser is obtained from various chemicals. It contains range of nutrients at different ratio, making it effective for plants. These are easily absorbed in plant systems. Organic Fertiliser are available as solid spray dried powder or liquid solution. This powder if fully soluble in water and can be dissolved in water to prepare formulation of required concentration HUMIC ACID: Application of humic acids has several benefits and agriculturists all over the world are accepting humic acids as an integral part of their fertilizer program. Biochemical active and plant responsive humic substance are naturally occurring humic acids. They can be applied directly to the plant foliage in liquid form or to the soil in the form of granules alone or as fertilizer mix. Benefits of Proper Application of Humic Acid increase soil fertility, Increase humus contents, Effectively chelates meta...

Complete defination of Fertilizers

FERTILIZERS : Growing plants are nourished by certain constituents which they absorb from the soil and air. The chief elements drawn from tho soil are potassium, calcium, sulphur, phosphorus, and nitrogen; other elements such as silicon, iron, sodium, magnesium, and chlorine are taken up to a less degree. The natural weathering of the minerals in the ground usually provide the elements necessary to plant life; but the supply of potassium, phosphorus, and nitrogen may be insufficient and become exhausted by frequent repetitions of the same crops on the same land. The soil becomes less productive, and finally the crops are failures. To supply this continued drain on the soil, fertilizers are employed. The natural fertilizers, barn-yard manure, urine, and decomposing vegetable mould or muck, will not be considered here, as they need little or no treatment before use. By artificial fertilizers we understand those manurial substances, prepared from materials which need some special treatmen...
