ideal solution chemistry

Ideal Solution - An Ideal solution is the one which obeys Roault's Law at all concentrations and temperature and during the formation of which no change in enthalpy and volume takes place i.e., P A = P o A X A P B = P o B X B If the solution is made..

According to ideal gas equation, PV = nRT T = 27 + 273 = 300 K, R=82.1 cm 3 atm K - 1 mol - 1 n = 0.0203 mol = 2.03 x 10 - 2 mol. 6. About 200 cm 3 of a gas is confined in a vessel at 20C and 740 mm Hg pressure. How much volume will it occupy at S.T.P..

. The dependence of solubility of a gas and its pressure above the solvent is given by a law known as Henry's law. This law states that 'the mass of a gas dissolved in a given mass of a solvent at a particular temperature is proportional to the pressure of the gas in equilibrium with the solut..

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 law kno..

Preparation of Colloidal Sols - For the preparation of lyophilic and lyophobic sols different methods are us..

Since lyophilic sols are quite stable, they can be easily prepared by shaking the lyophilic substance with the dispersion medium. Examples are: Colloidal sols of gum, starch, gelatine and egg album..

The colloidal solutions prepared by various methods usually contain electrolytes and other soluble substances as impurities. These impurities if not removed can destabilize the sols..

Heterogenous nature - Colloidal sols are biphasic in nature. It consists of the dispersed phase and the dispersion medium. In the colloidal solution, each particle is contained within its own surface boundary and therefore has a separate existence from the dispersion mediu..
