activity on 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 ..

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..

Make solutions of the following substances: 'Borax', 'Blood', 'Milk', 'caustic soda', 'Lemon Juice', 'Bleaching powder', 'Tomatoes', 'Vinegar', 'detergent', 'Pure Water', 'Coffee', Baking Soda'. Put a drop of each of the above solutions on a watch-glass and test by adding a dro..

Take about 1 ml each of concentrated hydrochloric acid and liquor ammonia in two different test tubes (Fig.5.7)...

Take two glass jars A and B. Collect sulphur dioxide gas in jar B and let jar A contain air. Carefully invert jar B containing sulphur dioxide, over the jar A containing air. Keep it for a few minutes (Fig. 7.3). Remove jar B and put a filter paper strip dipped in acidified potassium dichromat..

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...

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..

. Some light can be seen. The analyzer should be rotated so that once again no light reaches the eye. Note that some light could be seen when the cane-sugar solution tube was placed between the two prisms whose axes were perpendicular to each other and no light was visible originally. So ..

Water is absorbed due to activities going on in roots. Absorption of water occurs with the help of energy in the form of ATP, which is released due to metabolic activities of root cells such as respiration. Absorption takes place against concentration gradient - even w..
