natural solutions foundations

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..

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..

Borax is slightly hydrolyzed in solution. As boric acid is a weak acid, the solution is alkaline in 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 ..

Depending on the nature of pollutant, water is polluted with three kinds of pollutant..

0 - 8 : 2, 6Valency = 8 - Number of valence electrons= 8 - 6= 2 If the outermost shell of an atom is completely filled, its valency = 0. The outermost shells of the noble gases helium, neon, argon, krypton etc. are completely filled. Hence their valency is zero. Such elements are very un-reactive a..

>Increase in charge of the ion (cation or anion). Thus, Li + being small in size polarizes the anion and results in decrease of the positive charge on Li + ion. Therefore, lithium halides are covalent in nature..

. The form of energy, which cannot be recreated, is the amount that goes into increasing disorder. In reality a lot of effort and time is needed by nature to recreate energy once it goes through a spontaneous process. In the above example it is done through photosynthesis, carbonization o..

>Restrictions on rate of production Example: A coconut tree cannot bear more than 200 nuts. Restrictions on prerequisites for reproduction Example: Mating is successful within a species / subspecies. Climatic restrictions on existence of life and reproduction Example: Apple cannot be grown in tropi..

Introduction - Chemical reactions mostly take place in solutions. Solution chemistry plays a very significant role in chemistry. All chemical substances are made up of either polar units (called ions) or non-polar units. The activity of these entities is more evident and pronoun..
