An anhydrous, air-stable derivative is the urea complex Ca(NO 3) 2 ·4[OC(NH 2) 2], which has been sold as Cal-Urea. Calcium nitrate is also used to control certain plant diseases. For example, dilute calcium nitrate (and calcium chloride ) sprays are used to control bitter pit and cork spot in apple trees.
Infobox references. Calcium nitrite is an inorganic compound with the chemical formula Ca (NO. 2) 2. In this compound, as in all nitrites, nitrogen is in a +3 oxidation state. It has many applications such as antifreeze, rust inhibitor of steel and wash heavy oil. [1]
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to ...
Calcium nitride is formed along with the oxide, CaO, when calcium burns in air. It can be produced by direct reaction of the elements: [3] 3 Ca + N 2 → Ca 3 N 2. It reacts with water or even the moisture in air to give ammonia and calcium hydroxide: [4] Ca 3 N 2 + 6 H 2 O → 3 Ca (OH) 2 + 2 NH 3. Like sodium oxide, calcium nitride absorbs ...

Magnesium nitrate refers to inorganic compounds with the formula Mg (NO 3) 2 (H 2 O) x, where x = 6, 2, and 0. All are white solids. [ 2 ] The anhydrous material is hygroscopic, quickly forming the hexahydrate upon standing in air. All of the salts are very soluble in both water and ethanol.
Nitrophosphate process. The nitrophosphate process (also known as the Odda process) is a method for the industrial production of nitrogen fertilizers invented by Erling Johnson in the municipality of Odda, Norway around 1927. The process involves acidifying phosphate rock with dilute nitric acid to produce a mixture of phosphoric acid and ...
