Strontium Sulfate Formula

Strontium Sulfate Formula

Strontium Sulfate Formula is an alkaline earth metal with the atomic number 38 and the Sr symbol. It is a delicate silver-white metallic element with a high degree of chemical reactivity. If exposed to the air, it develops a thick oxide coating that is dark. It is a component of red signal flares and is used in the refining of zinc. Rocks, soil, water, and air all contain naturally occurring strontium. Strontium has a melting point of 777°C and a boiling point of 1377°C. One of the chemical components that are most readily accessible is sulfate. It has atmospheric and terrestrial processes and is primarily present in the environment. In essence, it is a chemical compound made up of sulfur and oxygen atoms. Together with other elements, such as sodium, potassium, calcium, and magnesium, it creates a salt. Strontium Sulfate has a molar mass of 96.06 gmol-1. Strontium Sulfate melts and boils at 270.47°C and 623.89°C, respectively.

Structure of SrSO4

On the Extramarks website, comprehensive details pertaining to Strontium Sulfate Formula, also known as SrSO4, are presented. The core atom of the molecule, sulfur, is produced from two strontium cations (Sr2+). Four oxygen atoms surround it for bonding, two of which form S=O bonds and the other two S-O- bonds. Strontium Sulfate Formula has a molar mass of 183.68 g/mol. Strontium Sulfate Formula has the chemical and molecular formula SrSO4. In the ionic composition of the Strontium Sulfate Formula, which is found in nature as white crystal powder, strontium and sulfate are both metals and non-metals. 

Preparation of strontium sulfate

A soluble strontium salt can be replaced with another soluble sulfate salt, such as ammonium sulfate, to create Strontium Sulfate Formula, or sulfuric acid can be added to strontium hydroxide or carbonate to create Strontium Sulfate Formula.

(NH4)2SO4 + SrCl2 → 2Cl(NH4) + Sr(SO4)

Properties Of Strontium Sulfate

Here are some physical and chemical properties of the Strontium Sulfate Formula. For access to more reference materials pertaining to this topic, students can access the Extramarks website.

Physical Properties of SrSO4

  • It is a white crystal or powder with crystals.
  • 1,606°C is its melting point of it.
  • Nitric acid and diluted HCl make it more soluble.
  • SrSO4 has a molecular weight of 183.68 g/mol.
  • SrSO4 has a density of 3.96 g/cm3.

Chemical Properties of SrSO4

Water H2O and strontium sulfate react to produce (Sr2+) and (SO42-).

SrSo4 + H2O ⇢ (Sr2+) + SO₄²–

Yellow strontium chromate is the product of the reaction between strontium and chromate.

Sr2+ (aq) + CrO2− 4(aq) ⇢ SrCrO4(s)

Uses of Strontium Sulfate

  • Glass and ceramics both employ it as a red colourant.
  • As a white artist pigment, it is employed.
  • Zinc is refined using it.
  • It is also employed in flares.

Sample Questions 

  1. Why is Strontium Sulfate Formula red?

Strontium chloride changes the flame’s colour to a scarlet-red hue. Metal-specific light characteristics are given off by metal salts that are involved in a flame. Additionally, each element has a well-specified line emission spectrum.

  1. How hazardous is Strontium Sulfate Formula?

It resembles an odourless, white powder with crystals. slowly decomposes when heated. Sulfur oxides, among other poisonous and corrosive gases, are produced.
