The vapour pressure of the four-phase equilibrium solid AgNO3-solid Pb(NO3)2-saturated solution-water vapour was measured from 10° C to the end point of this four-phase line. This end-point is the eutectic of the binary system AgNO3-Pb (NO3)2. This eutectic was subjected to exact ...
To find the molecular weight of the solute, we can use the concept of relative lowering of vapor pressure according to Raoult's law. Here’s a step-by-step solution:Step 1: Understand the given data - Vapor pressure of pure wat

IF a solution of a substance has a smaller surface tension than the pure solvent, the solute is adsorbed or concentrated at the surface, in accordance with Gibbs's theorem. It is therefore to be expected that the vapour pressure of the solvent of such a solution will be higher, when the...
Vapour pressure is a colligative property of solutions. The vapour pressure of a solution is always lower than the vapour pressure of the pure solvent. Ratio of solution to pure solvent vapour pressures is approximately equal to the mole fraction of solvent in the solution. Citing this page: Ge...
Raoult’s Law relates the vapour pressure of the solvent above the solution to its mole fraction in the solution. Which of the following is an accurate statement?A.Raoult’s Law applies exactly to all solutions.B.Raoult’s Law works best when applied to
the experimental vapour pressure data are in agreement with a derivation from the Clapeyron equation. Below 200 K cubic ice may affect the vapour pressure of ice both in the atmosphere and in the laboratory. All of the commonly used parametrizations for the vapour pressure of supercooled water ...
