5 methods of expressing concentration

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 component to the total numb..

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 component to the total number of moles (solute and solvents) present in the solution. It is expresse..

This contains high content of proteins and other nutrients but is low in fibres. These include grains of maize, oats, barley, jowar, gram and by-products of agriculture like wheat bran, rice bran, gram husk, oil seedcakes and molasses. A balanced feed, which contains all the nutrients in the right..

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 ions'. The..

The apparatus is set up as shown in figure 14.3. ..

A small known mass (0.2 to 0.3 g) of the given organic compound is heated with fuming nitric acid and a few crystals of silver nitrate at about 200C in a sealed tube (called Carius tube) for 5 to 6 hours. Carbon and hydrogen are oxidized to carbon dioxide and water while halogen forms a ..

Mass Percentage or Volume Percentage - The mass percentage of a component in a given solution is the mass of the component per 100g of the solution. For e.g., if W A is the mass of the component A, W B is the mass of the component B in a solution. The..

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 +..

x 2 - 2x - 48 = x 2 - 8x + 6x - 48 = x(x - 8) + 6(x - 8) = (x - 8) (x + 6) When the coefficient of the highest power is not unity. i.e., type ax 2 bx c, when and b and c are integers. Multiply (3x + 2) (x + 4) and consider the result so obtained. = 3x (x + 4) +2 (x + 4) = 3x 2 + 12x..
