ix,192p. PB 24x16cm. The present book is meant for the students who opt for a course in “Environmental Chemistry” with laboratory work as a component of the course. Spread in 72 experiments the analyses of soil, water and air have been described in a simple manner so that most of these experiments can be conducted even by the beginners in this subject. The principals involved, preparation of the reagents and the procedures are described for each experimental method. The authors hope that this manual would prove to be useful in laboratories where soil, water and air are routinely tested.
