Question

How much would the boiling point of water increase if mol of NaCl added 1 kg of water (Kb= 0.51 degrees Celsius /(mol/kg) for water i=2 for NaCl

Answer 1

The boiling point of water would increase by 1°C if 1 mol of NaCl added 1 kg of water.

What would be the change in the boiling point of water when NaCl is added to it?

The addition of solute substances to solvent such as water results in a change in the boiling points and freezing points of the solvents.

The formula to calculate the change in temperature is given below:

ΔT = Kbmi

Where;

m is molality of the solution

Kb and i are constants.

Solving for change in temperature:

m = 1 mol/kg

ΔT = 0.51 * 1 * 2

ΔT = 1°C

The normal boiling point of water is 100°C

The new boiling point of the solution = (100 + 1) = 101 °C

In conclusion, addition of solute to solvent will result in change in the boiling point of the solvent.
