Strontium oxide has a wide range of physical and chemical properties that make it a unique compound in the periodic table.

In this article, we will discuss its molar mass, color, viscosity, molar density, melting, and boiling points along with its electronic configuration, magnetic nature, crystal structure, polarity, and hydrates.

Molar Mass, Color, Viscosity, and Molar Density

The molar mass of strontium oxide is 103.62 g/mol, which is obtained by adding the atomic mass of strontium (87.62 g/mol) and oxygen (16.00 g/mol).

Strontium oxide is a white or yellowish crystalline solid, with a viscosity of 0.46 cP at room temperature. It has a molar density of 4.70 g/cm, which makes it heavier than other common compounds like water.

Melting and Boiling Points, State at Room Temperature

Strontium oxide has a very high melting point of 2,532C, making it a stable compound at high temperatures. It also has a high boiling point of 3,546C.

At room temperature, strontium oxide exists in a solid state.

Ionic Bond and Electronic Configuration

Strontium oxide is formed by the ionic bond between strontium (Sr) and oxygen (O) atoms. Strontium gives up its two valence electrons to oxygen and becomes a cation with a charge of 2+.

Oxygen, being an electronegative element, accepts these electrons and becomes an anion with a charge of 2-. The electronic configuration of strontium oxide is [Kr]5s, which shows that strontium oxide has an octet configuration.

Oxidation State, Acidity/Alkalinity, and Magnetic Nature

Strontium oxide has an oxidation state of +2, which is common for alkaline-earth metals. It is a basic oxide and has an alkaline nature.

When it reacts with water, it forms strontium hydroxide [Sr(OH)], which is a strong base. Strontium oxide is diamagnetic, which means it does not have any unpaired electrons and does not show any magnetic properties.

Hydrates

Strontium oxide can form hydrates by absorbing water molecules in the surrounding environment, forming new chemical compounds. The number of water molecules it can absorb depends on various factors like temperature and pressure.

The most common hydrates are monohydrate (SrO.HO) and hexahydrate (SrO.6HO).

Crystal Structure

The crystal structure of strontium oxide is similar to that of sodium chloride. It has a face-centered cubic structure in which strontium ions occupy the corners of the cube, and oxygen ions lie on the faces of the cube.

The crystal structure is important as it determines the physical properties of strontium oxide such as its melting and boiling points.

Polarity and Conductivity

Strontium oxide is a polar compound due to the difference in electronegativity between strontium and oxygen. The polarity of strontium oxide is observable when it reacts with water to form strontium hydroxide.

Strontium oxide does not conduct electricity as a solid because it lacks mobile charge carriers. However, it can conduct electricity in its molten form because of the presence of mobile ions.

Conclusion

In conclusion, we have explored the physical and chemical properties of strontium oxide, including its molar mass, color, viscosity, molar density, melting and boiling points, electronic configuration, magnetic nature, crystal structure, hydrates, polarity, and conductivity. Each of these properties is important in determining the behavior and use of strontium oxide in various fields.
