Notably, it has a molar mass of 96.06 g·mol-1 and melting and boiling points of 270.47°C and 623.89°C, respectively.
Strontium Sulfate Formula
Strontium sulfate formula is SrSO4. It is the sulfate salt of strontium, more commonly known as Celestine. This substance presents itself as a white crystalline powder and can be found naturally occurring. Its solubility characteristics include being soluble in dilute HCl and nitric acid, while it exhibits poor solubility in water and remains insoluble in ethanol. Notably, it is non-flammable. Strontium sulfate holds a pH level of 7.9, indicating a nearly neutral nature, not leaning towards acidity. This compound is the result of the combination of strontium cations (Sr2+ ) and sulfate anions (SO₄²–). It finds application as a red colorant in the production of ceramics and glass.
Strontium Sulfate Formula
The Strontium sulfate formula is SrSO4. It can be understood as a molecular arrangement where two strontium cations (Sr2+ ) surround a central sulfur atom. This sulfur atom, in turn, forms bonds with four oxygen atoms, with two of these oxygen atoms participating in S=O bonds, while the other two create S-O- bonds. The molar mass of strontium sulfate is 183.68 g/mol, making it a substantial compound. Thus, the chemical and molecular formula for strontium sulfate is accurately represented as SrSO4.
Strontium Sulfate Formula Structure
Strontium sulfate embodies an ionic compound, where strontium and sulfate represent the metal and non-metal elements, respectively. This compound is naturally occurring and appears as a white crystalline powder.
Strontium Sulfate Preparation
