Barium Hydroxide 8 hydrate
Barium hydroxide, with the chemical formula Ba(OH)2text{Ba(OH)}_2Ba(OH)2ā, is an inorganic compound that is used in various applications. Hereās a detailed overview:
Properties
- Appearance: White crystalline solid.
- Solubility: Moderately soluble in water, forming a strongly alkaline solution.
- Molecular Weight: 171.34 g/mol.
- Density: Approximately 2.18 g/cmĀ³.
- Melting Point: 78 Ā°C (anhydrous form); decomposes in water to form barium oxide and water.
Chemical Behavior
- Basicity: Barium hydroxide is a strong base and dissociates completely in water to form barium ions (Ba2+text{Ba}^{2+}Ba2+) and hydroxide ions (OHātext{OH}^-OHā).
- Reaction with Acids: Reacts with acids to form barium salts and water. For example: Ba(OH)2+2HClāBaCl2+2H2Otext{Ba(OH)}_2 + 2text{HCl} rightarrow text{BaCl}_2 + 2text{H}_2text{O}Ba(OH)2ā+2HClāBaCl2ā+2H2āO
- Hydrate Forms: Often found as the octahydrate (Ba(OH)2ā 8H2Otext{Ba(OH)}_2 cdot 8text{H}_2text{O}Ba(OH)2āā 8H2āO).
