Exercise 47

Solute dissolved in solvent will:

A. Raise the vapor pressure

B. Lower the boiling point

C. Decrease the osmotic pressure

D. Lower the freezing point

Step 1 of 2

Solute and solvent:

Solute and solvent are combined together to make a solution.

• Solute is the one which is to be dissolved (example: salt) and the solvent is the one which do the dissolving work. (Example: water). Because there will be tiny particles of solvent on the surface to evaporate.

• If vapor pressure is lowered, then freezing point lowers.

Freezing point:

• When cooled, if liquid changes into solid at certain temperature.

Therefore, “solute dissolved in solvent” will lesser the freezing point. Hence, the correct answer is option.
