What is Calcium Nitrate?

Calcium nitrate is an inorganic compound v the chemistry formula Ca(NO3)2.

You are watching: What is the chemical formula for calcium nitrate

Another name for Calcium nitrate is Norgessalpeter. It was synthesized by the Birkeland–Eyde process at Notodden, Norway in 1905. That is a nitrate salt that Calcium which has calcium and also nitrogen and oxygen. Calcium nitrate is a white or whitish-grey coloured granular solid i m sorry absorbs humidity from the air and also is usually found as a tetrahydrate compound Ca(NO3)2.4H2O.

Calcium Nitrate framework – Ca(NO3)2


Preparation that Calcium Nitrate

Calcium nitrate is a complicated fertilizer. It have the right to be ready by any kind of of the complying with methods.

1. Once calcium carbonate usually known as limestone is treated v nitric mountain calcium nitrate is formed. The reaction is together follows.

CaCO3 + 2HNO3 → Ca(NO3)2 + CO2 + H2O

2. Calcium nitrate is likewise formed when an ammonium nitrate solution is mixed with a calcium hydroxide solution. The reaction is as follows.

2NH4NO3 + Ca(OH)2 → Ca(NO3)2 + 2NH4OH

Chemical properties of Ca(NO3)2

1. ~ above heating, it experience decomposition and also releases nitrogen dioxide and also oxygen.

Ca(NO3)2 → CaO + 2 NO2 + ½ O2

2. On including calcium nitrate to sodium carbonate the precipitate the calcium carbonate is formed leaving salt nitrate in solution.

Ca(NO3)2 + Na2CO3 → 2 NaNO3 + CaCO3

Uses that Calcium Nitrate 

Used in farming as a fertilizer and in match manufacture together an oxidizing agent.It is likewise used in the explosives and pyrotechnics industries.It is supplied to make fireworks and incandescent desk lamp chimney in the irradiate industry.Used together a raw material in making various other nitrate compounds.Used to improve the storage high quality of plants reducing bitterness pit in apples.

In wastewater pre-conditioning because that odour pollution control, calcium nitrate is used. The pre-conditioning of waste water is focused on the breakthrough of anoxic biology in the wastewater system. The metabolism of sulphates end in the existence of nitrate, thereby staying clear of the production of hydrogen sulfide. In addition, straightforward degradable organic matter is ingested, which have the right to otherwise cause downstream anaerobic conditions and odour pollution. For excess sludge treatment, the an interpretation is also valid.

Calcium nitrate, specifically in dipping processes, is known to it is in a an extremely common coagulant in the manufacturing of latex. A part of the dipping bath systems often contains dissolved calcium nitrate. In the coagulation liquid, the warm previous is often dipped and a slim layer of the dipping liquid remains on the former. The calcium nitrate will certainly break up the stabilisation the the latex solution as soon as the former is dipped right into the latex and the latex will coagulate on the former.

This link can additionally be supplied in molten salt mixtures. Since the dissolved of this compound in water is extremely endothermic in nature, calcium nitrate can additionally be offered as a component of cold packs. The tetrahydrate of this compound can be provided in regeneratable cold packs.

Frequently Asked questions – FAQs

What space the offers of calcium nitrate?

One that the most vital applications the calcium nitrate is its use in wastewater treatment plants for the preconditioning that the wastewater in order to prevent the emission of foul odour. One more important usage of this link is in the construction industry, where it is offered as a component of collection accelerating concrete admixtures. In the manufacturing of latex, calcium nitrate is widely used as a coagulant, especially during the dipping phase of the manufacturing process. The dipping bath provided in the produce of latex usually includes a equipment of calcium nitrate.

Which solvents have actually the ability to dissolve calcium nitrate?

In that anhydrous form, calcium nitrate is very soluble in water and also its solubility at a temperature that 20 levels celsius coincides to 1212 grams per litre. Even the tetrahydrate that this link is extremely soluble in water, through a solubility of 1290 grams per litre at a temperature the 20 levels celsius. This link is additionally soluble in ammonia, ethanol, and also methanol. However, that is much much more soluble in methanol than ethanol. The solubility the this compound in ethanol at 40 levels celsius is 62.9 grams per 100 grams of ethanol. On the other hand, the solubility of this compound (at the same temperature) in methanol synchronizes to 158 grams per 100 grams of methanol.

How deserve to calcium nitrate be prepared?

Calcium nitrate have the right to be ready via several methods. The most common method of preparing this compound entails the treatment of limestone through nitric acid and the succeeding neutralization the the product developed with ammonia. This link is also produced as an intermediate during the nitrophosphate process (commonly recognized as the Odda process).

Why is calcium nitrate used in fertilizers?

Calcium nitrate is known to serve as a polytheistic fertilizer because it acts as a resource of both nitrogen and calcium. Thus, plants v deficiencies in either of this nutrients deserve to be treated through calcium nitrate. This link is specifically useful because that feeding fruit-bearing plants. Ca(NO3)2 is additionally used come treat or prevent specific plant diseases.

Is calcium nitrate dangerous?

Yes, calcium nitrate have the right to prove to it is in dangerous to human beings. Inhalation that this link can reason coughing and also soreness in the throat. Short-term side effects linked with exposure come this compound encompass dizziness, headaches, nausea, and also vomiting. Furthermore, prolonged exposure to this ionic salt can likewise lead come skin rashes, redness, and itchy skin.
