Vapour pressure is defined as the partial pressure exerted by the vapors above the liquid surface in equilibrium with liquid at a given temperatur..

Vapor Pressure of Solutions - Let us suppose a small amount of a non-volatile solute (sugar) is dissolved in a solvent (water). When evaporation of this solution takes place, only water evaporates as the other component (i.e., sugar) is non-volatile. The vapor pre..

In 1886 the French chemist Francois Marie Raoult carried out a series of experiments to study the vapor pressure of a number of binary solutions containing non-volatile as well as volatile non electrolyte solutes. On the basis of the results of the experiment he stated a l..

A known mass W B of the non-volatile solute is dissolved in a known mass (W A ) of the volatile solvent to prepare a dilute solution and relative lowering of vapor pressure is determined experimentally. Knowing the molecular mass (M A ) of the solvent, molecular mass (M B ) of..

Vapour pressure is defined as the partial pressure exerted by the vapors above the liquid surface in equilibrium with liquid at a given temperature. fig 3.3 In illustrations 1a and 1b, the liquid and vapor states of a given substance are represented. The indi..

. At pressure and temperature corresponding to any point on the fusion line, a substance C exists in equilibrium in solid and liquid phases. At pressure and temperature corresponding to any point on the fusion line, a substance coexists in equilibrium in solid and liquid phases...

. They overcome the inter-particle force of attraction and turn into a gas or vapor at its boiling point. Boiling point of the liquid is a temperature at which the vapor pressure of the liquid is equal to the atmospheric pressure. Changing the atmospheric ..

Liquids that have weak intermolecular forces are more volatile and have a higher vapor pressure. For e.g., vapor pressure of ethyl alcohol is greater than that of the wat..

In case of solutions showing positive deviation from Raoult's law, at one of the intermediate compositions, the total vapor pressure is the highest and the boiling point is the lowest. Similarly in case of solutions showing negative deviations from Raoult's law, at one of ..
