mechanical methods of expressing concentration of solution

Other Methods of Expressing Concentration of Solution - Molality is defined as the number of moles of solute dissolved per 1000 g (1 kg) of solvent. Molality is expressed as 'm'. Mole Fraction is the ratio of number of moles of one compone..

i) Microorganisms present in the soil weaken and decompose the hard seed coat ii) The digestive juices present in the alimentary canal of the fruit eating birds makes the seed coat soft iii) Mechanical abrasions weaken the tough and impermeable seed coat iv) Washing away of inhibitors by ..

Hydrogen Ion Concentration - In 1909, Sorensen introduced a term for expressing the concentration of hydrogen ions, which give an idea about the acidic and basic characters of the aqueous solution. This term was called 'pH' which means the 'power of hydrogen ..

Between two solutions, the solute quantity may be relatively more or less. The solution that has a greater proportion of solute is said to be concentrated more than the other that has a lesser proportion. If the proportion of solute is les..

We have seen that concept of ionic product of water enables us to classify solutions as acidic, basic or neutral by specifying H 3 O + ion concentration. The pH scale was devised by P.L Sorensen (1909) is defined as negative logarithm of hydronium ion concentration i..

The mixture of lead sulphide and Zinc sulphide ores are concentrated by the method of electrostatic concentration. The powdered ore is fed upon a roller in a thin layer and subjected to the influence of a electrostatic field. Lead sulphide being a good conductor gets ..

Here the products are X and Y and reactants are A and B. The powers of the concentrations of A, B, X and Y correspond to the respective number of moles in the equation. 6. Write down the expression for the equilibrium constants What is the relation between K p and K c for..

For reactions where many reactants are involved, the order of the reaction is determined by the method of isolation. This was developed by Ostwald. In this method, the concentrations of all the reactants except one are taken in excess. For e.g., in the reaction A + B +..

Adsorption of solutes from solutions also takes place on solids. Process of adsorption is used to reduce colors from solution. For e.g., raw sugar solution is decolorised by charcoal. Chromatographic separation of a mixture of compounds in solution ..
