Concentrated solutions and dilute solutions
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 more concentrated than the other that has a lesser proportion. If the proportion of solute is les..
Dilution
The molasses is diluted with water until a concentration of 8-10% sugar is obtained in solution. To discourage bacterial growth, this is acidified with a little sulphuric acid. If sufficient yeast (food for the ferment) is not present, a nutritive solution o..
b) Dilute solution
It is an unsaturated solution that contains comparatively small quantity of the solute, compared to what it can dissolve at that temperatur..
Concentration of a Solution
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..
Dilute nitric acid gives ring test
Dilute nitric acid is taken in a test tube and freshly prepared ferrous sulphate solution is added to it. Concentrated H 2 SO 4 is poured carefully along the side of the test tube. A dark brown ring is formed at the junction of the two layers. ..
c) Concentrated solution
It is a solution that contains comparatively a higher proportion of the solute, compared to what it can dissolve at that temperatur..
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 number of moles (solute and solvents) present in the solution...
Concentrated acid
An acid that has a relatively high percentage of the acid in the aqueous solution is classified as a concentrated acid e.g. concentrated hydrochloric acid, sulphuric acid, nitric acid, acetic acid et..
Solution
During the chemical reactions of metals HNO 3 not only acts as acid but also an oxidizing agent. The various stages of reduction of nitric acid are: Thus product of reaction consists of metal nitrates, water and reduction product of HNO 3 . The nature of the metal as well as the concentrat..
