This is an
exhaustive collection of laboratory chemistry hands-on experiments based on
basic techniques and principles. Some of the most important experiments
involved are: determination of density, titration of acid and bases, gas
diffusion, and the study of reaction rates. Among this list are experiments
concerning Hess's Law, molar masses, and critical solution temperatures.
This is a teaching document designed to help students gain practical skills
in the quantitative and qualitative analysis, prepare solutions for various
chemical reactions, as well as ways of finding out the concentration of
acids and bases, explaining organic compound behavior.
This is a very good
introduction to laboratory glassblowing techniques intended for novices who
require hands-on experience when handling glassware in laboratory settings.
It explains the general principles and tools of glassblowing, hence it
focuses on shaping, joining, and manipulating glass for the making of
laboratory apparatus. While the guide does not pretend to cover to cover the
field of commercial glass-blowing, it is rich in detail for any one learning
how to produce functional laboratory glassware. It would be a valuable
resource for chemistry students, lab technicians, and for all those
interested in acquiring glass-blowing skills applicable to laboratory use.
