Preface

Life is impossible without chemistry. Engineering chemistry has a special role to play in the curriculum

of under graduate students of all branches of Engineering. The present book entitled “ENGINEERING

CHEMISTRY LABORATORY MANUAL” is very useful to Engineering students of various

Institutions. The practical book providing simple and easy approach on the subject matter to Engineering

students. Through this laboratory manual, the author has made an effort to provide a balanced and easy to

understand the subject related matter which could be used by the students in their future endeavor while

working in various Institution or Industries. The different experiments which have been discussed in this

book have been designed in such a manner that it will give complete understanding about the Engineering

experiments. The main objective of the Lab Manual is to furnish the hypothesis understanding of the

fundamental principles of qualitative analysis involved, before the students perform lab experiments. This

book lays foundation of certain basic concepts and skills that can be repeatedly employed by the students

in their future endeavours. The main aim of this book is to develop the habit of scientific reasoning and

providing answers to any or all the doubts that arise throughout the course of conducting experiments.The

book was written as per the syllabus prescribed by the university in a simple language. Hence we tend to

hope this book serve better the student community with all details of experiments. I wish to express my

sincere gratitude to Dr. B.K. Agrawal, Chair principal, Dr. D.K. Singh, former Principal of Govt.

Engineering College Rewa and Dr. O.P. Gupta, Head of the Department Chemistry, Govt. Science

College Rewa, whose constant inspiration and encouragement had been a guiding force to write this

book. In particular I am thankful to Mr. R.U. Shubham, Lab technician, Govt. Engineering College Rewa

and also thankful to all faculty and staff of chemistry Department, Govt. Engineering College Rewa. Last

but not the least; I am thankful to my Father Mr. Rajaram Solanki, My Mother smt.Geeta Solanki, My

wife Ritu Solanki, My Son Himesh Solanki (Lucky) and Khushank Solanki (Anuj), My brothers Dilip

Engineering Chemistry Laboratory Manual 1. Introduction:

The Laboratory Manual serves as your text for the laboratorory portion of the courses for BE/B.Tech.

Carefully read through the experiment to be performed. Look up information on equipment, Glass

ware, materials and special techniques required for all the experiment accoding to syllabus. Complete

the lab assignment if given by faculty.

2. Important Instructions and Precautions for Students Safety and Emergency Information:

2 (i) Important Instructions for Students: 1. The all apparatus, Glass ware and other instruments used in lab should be handled with care and

responsibility.

2. Do not throw waste like; match sticks, filter papers and other material into the sink. They must be

thrown into the waste bin.

3. Put the water and gas taps closed except when these utilities be expected.

4. Replace the reagent bottles on the reagent shelves immediately after use. They must never be

allowed to accumulate on the bench.

5. Students should not move around in the lab.

6. Never cook the result by recording false observations or by making manipulated calculations.

7. Do not touch more concentrated acids and dangerous material or substances available or present

inlaboratory.

8. Do not enter the chemistry laboratory without permissin your lab instructor or faculty.

2 (ii) Precautions for Students: 1. While working in a chemistry laboratory suitable precautions should be observed to prevent any problem. 2. Always follow the experimental instructions strictly given by faculty or lab staf of the department. 3. The laboratory coat should be worn while working in the laboratory to protect the clothing from chemicals. 4. Use the fire extinguisher i.e.Carbon di oxide type available in the laboratory in case fire. 5. Use the first aid box in case of any problems. 6. Never work in the chemistry laboratory unless a faculty, Faculty, Lab technician or teaching assistant in present. 7. All the chemicals, equipment and glassware must be carefully handled. 8.
