Nature of solvent and solute
Polar solvent dissolves polar solutes and nonpolar solvents dissolve nonpolar solutes. For e.g., polar solvents like water, liquid ammonia, liquid hydrofluoric acid etc. dissolve polar and ionic compounds. Whereas nonpolar solvents like benzene, carbon disulphide, carbontetrach..

Both pollutant and contaminant are similar aspects of environment pollution. They both cause harm to the environment by being introduced in undesirable amounts. Pollutants refer to an excess of substances already present in nature. Oxides of nitrogen from vehicle exhaust in cities is an ..
Solution
(i) Sodium is heavier than potassium due to increase in atomic size of potassium, which makes its density lower. (ii) Sodium forms peroxides, which are colorless and diamagnetic with oxygen while potassium forms superoxide. The ion K + is larger and has a very weak positive field. Thus this i..

Colloidal sols are biphasic in nature. It consists of the dispersed phase and the dispersion medium. In the colloidal solution, each particle is contained within its own surface boundary and therefore has a separate existence from the dispersion mediu..
Stable nature
Colloidal solutions are quite stable. The colloidal particles do not settle at the bottom under the influence of gravity. This is because of the constant motion of colloidal particl..
Acidic nature
CO 2 dissolves in water to give carbonic acid. Therefore, carbon dioxide is called carbonic anhydride. Carbonic acid being a dibasic acid forms two sets of salts, the hydrogen carbonates HCO 3 - and carbonates, CO 3 2 ..

Very Very Very Fabulous tutor She is the BEST!! tutor I have met in tutorvista for ENGLISH. KEEP IT UP GOOD WORK WOW!! Thankyou
Tutor has given me a lot of good advise for my study. They has the package to be the best and the best teachers! they are not just have the teaching skills and understanding the subject matters as well. Thank you.
They always come through for me never fails me,great tutors,cant say thank u enough,lets hope we score big on the exams :-) - Jenna
Turtors are so good, and patient and most important knows their stuff. They really tutor in a very professional way. Their system is unique and they really knows how to explain and made sure you undertand. They even put stuff from a book into the white board, just to show me how the process of my question - Paul
