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).
Barlows wheel apparatus
The Barlow's wheel apparatus is an experimental device used to demonstrate the conversion of electrical energy into mechanical energy through electromagnetic principles. It consists of a horizontal wheel or disk with radial metal spokes attached to its center. The wheel is mounted on an axle, allowing it to rotate freely.
Barometer tubes
A barometer tube is a slender, sealed, and typically transparent tube used in barometers to measure atmospheric pressure. It is usually filled with a liquid, often mercury, but sometimes water or another fluid, which rises or falls within the tube in response to changes in atmospheric pressure. The height of the liquid column in the tube serves as an indicator of the current atmospheric pressure, with higher pressure causing the liquid to fall and lower pressure causing it to rise. This measurement helps in predicting weather changes and understanding atmospheric conditions.
beaker hysil
A glass beaker is a cylindrical, open-top container made of glass, typically with graduated volume markings on its side. It is commonly used in laboratories for holding, mixing, and heating liquids, as well as for performing various experiments and chemical reactions. Glass beakers come in various sizes and are designed to provide easy observation of the contents and to withstand temperature changes without significant deformation or chemical interaction with the substances being used.
Beaker Plastic
A plastic beaker is a laboratory container made from plastic material, typically featuring a cylindrical shape with a flat bottom and a spout or pouring lip. It is used for holding, measuring, and mixing liquids or substances during various scientific experiments, research, or educational activities. Plastic beakers come in a range of sizes and are designed to withstand various chemicals and temperatures, making them versatile tools in laboratory settings.
