Solubility in water. anhydrous: 710 g/L (18 °C) 660 g/L (20 °C) tetrahydrate: ... Strontium nitrate is an inorganic compound composed of the elements strontium, ...
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.
The table below provides information on the variation of solubility of different substances (mostly inorganic compounds) in water with temperature, at one atmosphere pressure. Units of solubility are given in grams of substance per 100 millilitres of water (g/ (100 mL)), unless shown otherwise. The substances are listed in alphabetical order.
Because Sr(OH) 2 is slightly soluble in cold water, its preparation can be easily carried out by the addition of a strong base such as NaOH or KOH, drop by drop to a solution of any soluble strontium salt, most commonly Sr(NO 3) 2 (strontium nitrate). The Sr(OH) 2 will precipitate out as a fine white powder.
Strontium carbonate is a white, odorless, tasteless powder. Being a carbonate, it is a weak base and therefore is reactive with acids. It is otherwise stable and safe to work with. It is practically insoluble in water (0.0001 g per 100 ml). The solubility is increased significantly if the water is saturated with carbon dioxide, to 0.1 g per 100 ml.
Strontium chloride (SrCl 2) is a salt of strontium and chloride. It is a 'typical' salt, forming neutral aqueous solutions. As with all compounds of strontium, this salt emits a bright red colour in flame, and is commonly used in fireworks to that effect. Its properties are intermediate between those for barium chloride, which is more toxic ...
Inhaling the compound irritates mucous membrane in the lungs. Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). Strontium oxalate is a compound with the chemical formula SrC2O4. Strontium oxalate can exist either in a hydrated form (SrC2O4·nH2O) or as the acidic salt of strontium ...
Infobox references. 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.
