Question

Define 'colligative properties'. The boiling
point of chloroform was raised by 0-320 K when
5.15 x 104 kg of an organic compound was
dissolved in 3-50 10-2 kg of chloroform.
Calculate the molar mass of the organic
compound. Molal elevation constant for
chloroform is 3.90 K kg mol​

Answer 1

Answer:

The properties of a solution are different from those of either the pure solute(s) or solvent. Many solution properties are dependent upon the chemical identity of the solute. Compared to pure water, a solution of hydrogen chloride is more acidic, a solution of ammonia is more basic, a solution of sodium chloride is more dense, and a solution of sucrose is more viscous. There are a few solution properties, however, that depend only upon the total concentration of solute species, regardless of their identities. These colligative properties include vapor pressure lowering, boiling point elevation, freezing point depression, and osmotic
