Information about barium hydroxide
Are you looking for all the information about barium hydroxide from its definition to its use? You have reached your destination because ECHEMI provides all the information on the subject of barium hydroxide here - definition, chemical structure, properties and uses. This topic starts with definitions, and then discusses everything relevant to that topic.
Barium hydroxide is a white granular compound. It is composed of barium oxide and water. It is mainly used to produce other barium products. The chemical formula of barium hydroxide is Ba (OH)2. One of the main compounds of barium is its monohydrate, also known as barite or barite water. However, in the commercial field, white grain barium water is used for many applications.
Chemical Structure of Barium Hydroxide
The chemical formula of barium oxide is Ba (OH)2. The chemical formula of barium hydroxide is very interesting. As can be seen from the name, barium hydroxide is composed of barium and hydroxide. Therefore, logically speaking, the formula should be Ba (OH). So why do we write Ba (OH)2 into the formula of barium hydroxide? This is because barium has two positive ions, while hydroxide has only one negative ion. To show that barium is a neutral compound, we add another hydroxyl radical to the hydroxyl radical to make it neutral.
Properties of barium hydroxide
Molar mass
To find the molar mass of barium hydroxide, we need to add the molar mass of the elements that make up this compound. The molar mass or molecular weight of barium is 137.33. There is only one kind of barium in the courtyard. The molar mass of hydrogen is 1.008. There are two hydrogens in the compound. So the total molar mass of the two hydrogens is 2.016. The molar mass of oxygen is 15.999. There are two oxygen, so the total molar mass of the two oxygen is 31.998. Now add these numbers together to get 171.344. Therefore, the molar mass of barium hydroxide is 171.344g/mol.
Barium oxide: strong alkali
Alkali is a chemical substance that reacts with water to form hydroxyl ions. Strong bases can be completely dissociated in water, releasing the same amount of anions and cations as the elements in the undissolved base.
Melting point
The melting point of barium hydroxide varies with its water content. The octahydrate form of barium oxide melts at 78 ℃. A water form melts at 300 ℃, and an anhydrous form melts at 407 ℃.
Solubility
Although barium hydroxide is soluble in water, it is only slightly soluble. If you want barium hydroxide to be soluble in water, you need a barium hydroxide compound with a molar concentration of 0.1 M.
Boiling point
Barium hydroxide boils at 780 ℃. If the boiling continues and the temperature reaches 800 ℃, it will decompose and release barium oxide.
Other properties of barium hydroxide
Barium hydroxide is white.
It usually appears as a granular solid.
It is tasteless.
The pH of barium hydroxide is 11.27
The density of barium hydroxide in water form is 3.74g/cm3. The density of octahydrate is 2.18g/cm3.
