Electrolytes
The physical chemistry of electrolytic solutions is a special area of physical chemistry. The dissolution of a salt in water was described by Arrhenius as a dissociation of the salt in positive and negative ions of free mobility. This was originally a difficult suggestion to accept because salts were very stable substances.

What is the physical chemistry of oxide fuels?
The physical chemistry of oxide fuels is an exceedingly daunting technical matter in view of the number of elements and potential phases involved, not to mention the complications of conducting experiments at high temperatures with radioactive systems. Moreover, the elemental composition of the fuel is changing with time and the chemical speciation is influenced by exposure to steam or coolant water in the event of a clad failure or other materials in the case of a reactor accident. Nevertheless, advances by those referenced in computational methodologies rooted in numerical modeling linked to Gibbs energy minimization and related phase field theory are making possible substantial and exciting progress.
Why are cleaning processes so complex?
Cleaning processes are very complex due to the different parameters and effects that are involved in these systems. This becomes especially evident when one considers such different processes as household cleaning and detergency or personal care and institutional and industrial cleaning. Even processes like foam flotation in mineral processing or in waste paper treating can be regarded as cleaning steps. A very useful approach to study these processes in a more systematic way and to get more information about the physical chemical basics is given in Figure A.1. According to this the cleaning process can be divided into four different key factors: chemistry, mechanical action, thermal effects and time [ 1]. These factors are in most cases interdependent and guarantee the overall cleaning and washing results. Dependent on the substrate which has to be cleaned and the soil, one of these factors can be dominant or all factors can have similar influence. As the overall process is very complex due to these key factors, the different substrates, different solvents and the complex composition of cleansers and detergents, this chapter will mainly focus on the physical chemistry of cleaning processes in aqueous systems. As a majority of the published physical chemical studies deal with the washing of fabrics in aqueous detergent solutions, many of the shown examples will be in connection with this process but can be transferred also to other cleaning processes.

The key concepts of physical chemistry are the ways in which pure physics is applied to chemical problems.
One of the key concepts in classical chemistry is that all chemical compounds can be described as groups of atoms bonded together and chemical reactions can be described as the making and breaking of those bonds. Predicting the properties of chemical compounds from a description o…
