What is BeCl2? Important knowledge about BeCl2.

1. Definition of BeCl₂

BeCl₂, also known as Beryllium chloride or Beryllium dichloride, has a molar mass of 79.919 g/mol consisting of one Beryllium atom (Be) and two Chloride atoms (Cl) linked together to form a molecule. BeCl₂ has an ionic structure with Be₂+ and 2Cl- ions.

2. Properties: BeCl₂

2.1 Physical properties of BeCl₂

Under standard conditions (25 degrees C, 1 atm), BeCl₂ is a white, odorless solid. It has a neutral pH when insoluble in water.

2.2 Chemical properties of BeCl₂

BeCl₂ can react with water to form Be(OH)₂ and HCl. It also reacts with alkali metals to form Be salts and releases Cl₂ gas.

3. Actual chemical equation: BeCl₂

BeCl₂ reacts with metals such as Na, K, Ca, Mg to form Be salts and Cl₂ gas. It can also react with strong acids like H₂SO₄, HCl to form Beryllium salts and release Cl₂ gas. BeCl₂ also undergoes reactions with non-metals like S, P, C to form complex compounds.

4. Preparation of BeCl₂

4.1 Laboratory preparation of BeCl₂

BeCl₂ is prepared by reacting Beryllium with Cl₂ at high temperatures.
4.2 Industrial preparation of BeCl₂

On an industrial scale, BeCl₂ is usually produced by heating beryllium with chlorine.
