Question

Ionic compounds are soluble in organic solvents. State whether the given statement is True or False

Answer 1

We need to remember that the ionic compounds are held together by ionic bonds and categorized as ionic compounds. The crystalline solids formed by neatly packed ions of opposite charge. Ionic compounds are usually formed when metals react with non-metals.

Complete answer:
We must need to know that the ionic compounds are easily soluble in any liquid that is capable of breaking the ionic bond in them. Water breaks the ionic bond by hydrogen bonding, as water itself has a more ionic bond and is polar in nature. Many other solvents such as kerosene and petrol are not capable of breaking the ionic bond. Hence, cannot dissolve them, and they all have covalent bonds which are non-polar in nature. Most ionic compounds are soluble in water. Polar water molecules have a strong attraction for charged ions and the charged ions become solvated as they dissociate into water and ionic compounds are soluble in water. Kerosene is a non-polar organic solvent and dissolves only non-polar covalent compounds. Non polar substances have the capability to dissolve in non-polar solvents. For instance, non-polar molecular substances are likely to dissolve in hexane, which is a non-polar solvent and ionic compounds are insoluble in hexane.

Note:
As we know, ionic compounds are soluble in polar solvents and insoluble in non-polar solvents. Non-polar solvents like kerosene, benzene are not capable of dissolving ionic solids since they cannot decrease the forces of attraction between the ions. The water molecules have high dielectric constant thus; water molecules easily break the ionic bonds between the ions.
