formula for concentration of a solution

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..

Lyophobic sols are prepared by two methods. They are: 1) Condensation methods 2) Dispersion method..

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. Impurities are removed by the following methods: 1) Dialysis 2) Ultra-filtration 3) Ultra-Centri..

Here, the electrolyte is AgNO 3 and the electrodes are silver plates. The process of electrolysis is identical to that of CuSO 4 solution, except for one important difference. Copper has valency two, while silver has valency one. The reactions at the electrodes are So, silver gets ..

. 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..

. Such a solution is said to be unsaturated. However, if we continue adding sugar to the same amount of water at same temperature, a stage is reached when no more sugar appears to dissolve. At this point the solution is said to be saturated because the concentration of..

Concentration of Reactants - In most cases, the rate of a reaction is accelerated with increase in concentration of a reactant. A piece of wood burns faster in oxygen than in a..

High concentration of nucleophile favors S N 2 , while low concentration favors SN 1 mechanis..

In most cases, the rate of a reaction is accelerated with increase in concentration of a reactant. A piece of wood burns faster in oxygen than in a..

The rate of a reaction generally increases with increase in concentration of the reactants. For a reaction to take place between two molecules, they must collide or come into contact. The probability of such collisions increase with the increase in the concentration of the reac..
