Question

How does lead bromide solution ionise in water which is a polar covalent solvent?

Answer 1

Answer:
Covalent bonds do not dissolve in water.
Explanation:
Rather, compounds with covalent bonds dissolve in water.
The water surrounds the polar sites of the molecules at the interface with the solute (whether it is a solid, a liquid, or a gas) and strips the molecules away.
When a solute dissolves in a solvent, the individual particles of the solute separate from their neighbours and move between the spaces of the solvent particles.
The solvent particles collide with the solute particles and the intermolecular forces of attraction between solute and solvent particles "hold" the solute particles in the spaces.

There are three steps to the dissolving process:
The solvent particles must move apart to make room for solute particles. This process requires energy to overcome forces of attraction between solvent particles. This first step is endothermic.

The solute particles must separate from their neighbours. This process also requires energy to overcome the forces of attraction between the solute particles. The second step is endothermic.

When the solute particles move between the solvent particles, the intermolecular forces of attraction between solute and solvent take hold and the particles "snap" back and move closer. This process releases energy. The final step in the dissolving process is exothermic.
