When KBr is dissolved in water, it gets dissociated into its potassium and bromide ions. This property makes KBr useful for double displacement reactions or salt metathesis reactions.

boiling point of kbr is C

The boiling point of any liquid is the maximum amount that can dissolve in the same volume of water at a particular temperature. Solubility is the maximum amount of a solute that can dissolve in a known quantity of solvent at a given temperature and pressure.

Temperature plays an important role in solubility as the kinetic energy of the particles increases, more collisions are possible. This is why many substances are more soluble at higher temperatures.

Solubility of KBr at 80degC

The solubility of KBr is around 95 g/100g H2O which is nearly twice as much as the solubility of potassium nitrate at the same temperature.

Solubility of KBr is affected by the number of collisions between the particles in the solution. When there are more particles, the number of collisions is greater and so is the amount of KBr that dissolves in the water.

Van’t hoff factor (i) is 2.

When an electrolyte such as kbr is used, the number of ions after dissociation will be larger than the number of particles, so this increases the value of the Van’t hoff factor. As a result, the boiling point of kbr is higher than the boiling point of pure kbr because of the number of particles after dissociation.
