Impurities of brine solution

  • calcium chloride
  • calcium sulphate
  • magnesium chloride
  • sodium sulphate

Characteristics of halides of beryllium

  • covalent bond
  • does not conduct electricity
  • In organic solvents, it is soluble.

Answer:

Explanation:

3.

Brine is a concentrated solution of sodium chloride. Strictly speaking, sodium chloride does not exist in the solution as it completely dissociates into Na+ and Cl- in water.

Other ions that may exit include Potassium (K+), Magnesium (Mg++), Calcium (Ca++), Bromide (Br-), Iodide (I-)

4.

The only halide of Beryllium that is ionic is BeF2 while other halides like BeCl2, BeBr2 and BeI2 are highly covalent.

Beryllium halides are mostly covalent due to smaller size and relatively high charge on Be+2 ion.

Another fun fact about Beryllium Floride is that it exists as a glass in solid state, with four-coordinate Be(2+) tetrahedral centers and two-coordinate fluoride centers.
