Study tips and resources for Chapter 7 – Physical Chemistry by Laidler, Meiser, Sanctuary

Can you be Electrocuted while showering during an Electric Storm?

Lightning on the Columbia RiverIt is a known fact that water and electricity should not be used at the same time but have you ever wondered why? Were you ever told that you could be electrocuted while showering or bathing, during an electric storm? Can an electric current really flow through water? Continue reading

Arrhenius Theory in Relation to Acids, Bases and Electrolytes

Strong and weak electrolytes

The Arrhenius theory of electrolytic dissociation is expressed in Chapter 7.3 of the Physical Chemistry book. The theory stated that electrolytes such as acids, bases and salts dissociated into their component ions in aqueous solution.

Arrhenius further stipulated that some electrolytes dissociated completely (strong electrolytes) and some dissociated only partially (weak electrolytes) (Fig. 7.2 above). The Arrhenius theory was later used to explain the acid-base concept. Continue reading

Physical Chemistry textbook
by Laidler, Meiser, Sanctuary


This popular Physical Chemistry text book is now available in electronic format. We have preserved much of the material of the former hard copy editions, making changes to improve understanding of the concepts in addition to including some of the recent discoveries in physical chemistry. Many chapters have new sections and the coverage of several chapters has been greatly expanded.
