Preface to the Nineteenth Edition
A
common idea prevails that when Language of Chemistry constitutes a part of Inorganic Chemistry textbooks, what is the justification of bringing out a seperate booklet To those teachers and students of chemistry, who share this view we have to offer a word of apology. No textbook provides a sufficient number of equations to the students for practice. Moreover, the equations given are always written in the language of chemistry. The student simply reads these equations from the textbook and copies them. He never gets any practice in writing equations, with the result that he cannot balance them in any test. He loses interest in the subject and regards it as something beyond his reach. In this small booklet a large number of equations are written in words and the students is required to translate them into the language of chemistry. He has to write correct formulae and then balance the equations independently. For verification of the result, he can look up the answers given at the end. Just in a week or two he learns the method of writing correct balanced equations. He feels interested in the subject and finds it quite his own. For writing and naming of formulae the chemists prefer the Stock system of nomenclature. So modern names are introduced
