Barium oxide is also called “Baria.” Let us focus on the properties of barium oxide.
Barium oxide is a non-flammable compound. When it comes in contact with the environment absorbs water. Large quantities of barium oxide result in irritation, and excessive quantity may cause death. It is produced by the process of thermal decomposition of barium nitrate.
Barium oxide is used as a catalyst in many reactions. Let us predict the IUPAC name, CAS number, ChemSpider ID, and more such facts in this article.
Barium oxide IUPAC name
IUPAC name of Barium oxide is barium, monoxide, or Oxo barium.
Barium oxide chemical formula
Barium oxide has the chemical formula BaO. This Barium contains 2 electrons and oxygen 6 electrons. Barium donates two electrons to oxygen and gains Ba2+ and oxygen O2- state.
Barium oxide CAS number
The CAS number for barium oxide is predicted as 1304-28-5.
Barium oxide ChemSpider ID
ChemSpider ID for barium oxide is 56180.
Barium oxide chemical classification
- Barium oxide is an ionic compound.
- Barium oxide is a combination of Barium, a metal cation, and oxygen, a non-metal anion forming a metal oxide.
- Barium oxide can be written as below.
Barium oxide molar mass
The molar mass of barium oxide is found to be 153.33g/mol.
Barium oxide colour
The colour of Barium oxide varies from white to yellow.
Barium oxide molar density
The molar density of Barium oxide is 5.72 g/cm3.
Barium oxide melting point

Barium oxide boiling point
Barium oxide boil at ~ 20000C (36300 F, 2270 K).
Barium oxide state at room temperature
Barium oxide occurs solid at room temperature.
Barium oxide ionic bond
Bond in barium oxide is found to be ionic where the transfer of electrons takes place from Barium to oxygen.
Barium oxide ionic radius
In Barium oxide, the ionic radius of Ba2+ is 1.34 A0 and the ionic radius of O2- is 1.32 A0.
Barium oxide electron configurations
Electrons are arranged in a particular shell around the nucleus; this is called an electronic configuration. Let us take a look at the electronic configuration of barium oxide.
The electron configuration of Barium and Oxygen in Barium oxide is given below.
Ba → [Xe] 6s2
O → 1s2 2s2 2p4
Barium oxide oxidation state
Barium oxide shows a +2 oxidation state for Barium and a -2 oxidation state for oxygen.
Barium oxide acidity/alkaline
Barium oxide is alkaline in nature. As we know, Barium is a metal when it reacts with water, giving basic oxide.
Is barium oxide odorless?
Barium oxide is found as an odorless powder.
Is barium oxide paramagnetic?
The presence of unpaired electron shows the paramagnetic property and paired electron shows diamagnetism. Let us see whether BaO is paramagnetic or diamagnetic.
Barium oxide is diamagnetic in nature as it contains O2- which does not have unpaired electrons.
Barium oxide hydrates
Barium oxide reacts with water and gives barium hydroxide, which is also called barium oxide hydrates.
BaO+H2O → Ba ( OH2 )
Barium oxide crystal structure
The crystal structure of Barium oxide is predicted as cubic CF8.
| Crystal family | Centering type | Atom in conventional unit cell |
|---|---|---|
| cubic | all faces centered | number |
| c | F | 8 |
Barium oxide polarity and conductivity
- Barium oxide is a polar molecule. The bond polarity value for barium oxide is 2.5, which is calculated by the electronegativity difference between atoms.
- Barium oxide shows a conductivity value of 10-4 mho/cm at 10000 K in white crystals, and blue crystals show a value of 1 mho/cm at about 9000 K.
Barium oxide reaction with acid
Barium oxide reacts with sulphuric acid to give barium sulfate and water as a product. Barium oxide reacts with hydrochloric acid to give barium chloride.
BaO(s) + H2SO4 (l) → BaSO4 (s) +H2O (l)
BaO + 2HCl (dilute) → BaCl2 +H2O
Barium oxide reaction with base
Barium oxide do not react with base as it is a basic metal oxide.
Barium oxide reaction with oxide
The reaction between carbon dioxide and barium oxide gives barium carbonate.
CO2 + BaO → BaCO3
Barium oxide reaction with the metal
The reaction between barium oxide and metal like aluminum gives elemental Barium solid aluminum oxide as the product. This reaction takes place at high temperatures.
BaO (s) + Al (s) → Ba (s) + Al2O3 (s).
Conclusion
Barium oxide is used in fuels. Optical crown glass can be produced from barium oxide. It is used in coating hot cathodes. It plays an important role in isomer separation.
