what is a pressing concentration of solution

Nitric acid can be concentrated up to 68%. It cannot be concentrated beyond this percentage by simply boiling because the aqueous solution of this concentration of nitric acid forms a constant boiling mixture at 121 o C. However, the acid can be further ..

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..

It is a solution that contains comparatively a higher proportion of the solute, compared to what it can dissolve at that temperatur..

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...

Hydraulic press is used to compress soft materials like cotton, paper, and cloth. These soft materials are placed on the larger piston as sho..

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..

If an electrolyte contains a higher concentration of ions, which are higher in the electrochemical series than those that are lower, then these ions get discharged in preference to the lower ones. For e.g., a solution of sodium chloride in water contains two types of anions i.e..

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 pH is defined as "the negative logarit..
