Question

Potassium chloride (KCl), sodium sulfate (Na2SO4), glucose (C6H12O6), and sodium phosphate (Na3PO4) are soluble in water. Rank the solution from the lowest impact on phase change temperatures to highest based on colligartve properties if they all have the same molarity concentration.

a. KCl
b. Na2SO4
c. C6H12O6
d. CO2
e. (NH4)3PO4

Answer 1

(NH4)3PO4 > Na2SO4 > KCl > C6H12O6 > CO2

Step-by-step explanation:

Colligative properties are those properties that depend on the amount of solute present in the system.

Usually, the more the number of particles in the system, the greater the impact of colligative properties on phase change temperatures if all the solutions have the same molarity concentration.

Hence, the order of impact on phase change temperatures is as follows; (NH4)3PO4 > Na2SO4 > KCl > C6H12O6 > CO2
