molecules are in contact with surface of solid. However, the rate at which the solvent molecules leave the surface of solid remains unchanged. That is why temperature is lowered to restore the equilibrium. The freezing point depression in an ideal solution is proportional to molality of the ...
Colligative Properties. Colligative properties of solutions are properties that depend upon the concentration of solute molecules or ions, but not upon the identity of the solute. Colligative properties includevapor pressure lowering, boiling point elevation, freezing point depression, and osmotic pressure....
Write the mathematical expression for boiling-point elevation and freezing point depression. Label and define the terms used in each. Consider the following solutes dissolved in separate solutions with a concentration of 0.100 mol/L. Which solute would have the greatest impact on the colligative prope...
Assertion (A): Larger the value of cryoscopic constant of the solvent, lesser will be the freezing point of the solution. Reason (R ): Depression in the freezing point depends on the nature of the solvent. View Solution The freezing point of cyclohexane is 6.5∘C. A solution of 0.65...
Answer and Explanation:1 Molality is defined as the number of moles of solute present in the total mass of the solvent in Kg. Its units are Molal (m) and mol/Kg. 1 molal is... Learn more about this topic: Molarity vs Molality | Comparison, Formula & Examples ...
Step-by-Step Text Solution:1. Definition of Precision: Precision refers to the closeness of two or more measurements to each other. It indicates how consistently a measurement can be repeated.2.
By dissolving13.6gof a substance in20gof water, the freezing point decreased by3.7∘C. Calculate the molecular mass of the substance. (Molal depression constant for water=1.863Kkgmol−1) View Solution The molecular mass of a substance is the relative mass of its molecule as compared wi...
