Strontium nitride, Sr 3 N 2, is produced by burning strontium metal in air (resulting in a mixture with strontium oxide) or in nitrogen. Like other metal nitrides, it reacts with water to give strontium hydroxide and ammonia: Sr 3 N 2 + 6 H 2 O → 3 Sr(OH) 2 + 2 NH 3
Strontium nitrate is an inorganic compound composed of the elements strontium, nitrogen and oxygen with the formula Sr(NO 3) 2. This colorless solid is used as a red colorant and oxidizer in pyrotechnics .
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 precipitate.
Examples include beryllium nitride (Be 3 N 2), magnesium nitride (Mg 3 N 2), calcium nitride (Ca 3 N 2), and strontium nitride (Sr 3 N 2). The nitrides of electropositive metals (including Li, Zn, and the alkaline earth metals) readily hydrolyze upon contact with water, including the moisture in the air: Mg 3 N 2 + 6 H 2 O → 3 Mg(OH) 2 + 2 NH 3
Strontium is intermediate between calcium and barium in its reactivity toward water, with which it reacts on contact to produce strontium hydroxide and hydrogen gas. Strontium metal burns in air to produce both strontium oxide and strontium nitride , but since it does not react with nitrogen below 380 °C, at room temperature it forms only the ...
Water-reactive substances [1] are those that spontaneously undergo a chemical reaction with water, often noted as generating flammable gas. [2] Some are highly reducing in nature. [ 3 ] Notable examples include alkali metals , lithium through caesium , and alkaline earth metals , magnesium through barium .
Strontium oxide or strontia, SrO, is formed when strontium reacts with oxygen. Burning strontium in air results in a mixture of strontium oxide and strontium nitride. It also forms from the decomposition of strontium carbonate SrCO 3. It is a strongly basic oxide.
Reaction with nitrogen. Only Be and Mg form nitrides directly. 3Be + N 2 → Be 3 N 2 3Mg + N 2 → Mg 3 N 2. Reaction with hydrogen. Alkaline earth metals react with hydrogen to generate saline hydride that are unstable in water. Ca + H 2 → CaH 2. Reaction with water. Ca, Sr, and Ba readily react with water to form hydroxide and hydrogen gas.
