Ancient Indian and Greek philosophers have
always wondered about the unknown and unseen form of matter. The idea of divisibility of matter was considered long back in India, around 500 BC. An Indian philosopherMaharishi Kanad, postulated that if we go on
dividing matter (padarth), we shall get smaller and smaller particles. Ultimately, a time will come when we shall come across the smallest particles beyond which further division will not be possible. He named these particlesParmanu. Another Indian philosopher,
Pakudha Katyayama, elaborated this doctrine
and said that these particles normally exist in a combined form which gives us various forms of matter.Around the same era, ancient Greek
philosophers - Democritus and Leucippus suggested that if we go on dividing matter, a stage will come when particles obtained cannot be divided further. Democritus called these indivisible particles atoms (meaning indivisible). All this was based on philosophical considerations and not much experimental work to validate these ideas could be done till the eighteenth century.By the end of the eighteenth century,
scientists recognised the difference between elements and compounds and naturally became interested in finding out how and why elements combine and what happens when they combine.Antoine L. Lavoisier laid the foundation
of chemical sciences by establishing two important laws of chemical combination.3.1Laws of Chemical Combination
The following two laws of chemical
combination were established after muchexperimentations by Lavoisier and JosephL. Proust.
3.1.1LAW OF CONSERVATION OF MASS
Is there a change in mass when a chemical
change (chemical reaction) takes place?Activity______________3.1Take one of the following sets, X and Y
of chemicals- XY (i)copper sulphatesodium carbonate (ii)barium chloridesodium sulphate (iii)lead nitratesodium chloridePrepare separately a 5% solution of any one pair of substances listed under X and Y in water.Take a little amount of solution of Y in a conical flask and some solution of X in an ignition tube.Hang the ignition tube in the flask carefully; see that the solutions do not get mixed. Put a cork on the flask (see Fig. 3.1).Fig. 3.1: Ignition tube containing solution of X, dipped in a conical flask containing solution of Y.3 AA AAATOMSTOMSTOMSTOMSTOMS ANDANDANDANDAND M M M M MOLECULESOLECULESOLECULESOLECULESOLECULESC hapterSCIENCE32Weigh the flask with its contents
carefully.Now tilt and swirl the flask, so that thesolutions X and Y get mixed.Weigh again.What happens in the reaction flask?Do you think that a chemical reaction
has taken place?Why should we put a cork on the mouth of the flask?Does the mass of the flask and its contents change?Law of conservation of mass states that
mass can neither be created nor destroyed in a chemical reaction.3.1.2LAW OF CONSTANT PROPORTIONS
Lavoisier, along with other scientists, noted
that many compounds were composed of two or more elements and each such compound had the same elements in the same proportions, irrespective of where the compound came from or who prepared it.In a compound such as water, the ratio of
the mass of hydrogen to the mass of oxygen is always 1:8, whatever the source of water.Thus, if of water is decomposed, of
hydrogen and of oxygen are always obtained. Similarly in ammonia, nitrogen and hydrogen are always present in the ratio 14:3 by mass, whatever the method or the source from which it is obtained.This led to the law of constant proportions
which is also known as the law of definite proportions. This law was stated by Proust as "In a chemical substance the elements are always present in definite proportions by mass".quotesdbs_dbs7.pdfusesText_5[PDF] tokens expressions and control structures in c++
