What is a reaction? This topic answers this question and discusses collision theory and factors which affect a chemical reaction.
REDOX (REDuction and Oxidation) reactions are types of reacitons which are very important in our world, understanding these reactions can help use understanding concepts such as rusting and how batteries work.
Most of the early work in chemistry focused on reactions which happened in one direction. This topic talks about reversible reactions, how they can occur, the notion of an equilibrium and more indepth discussions including calculations.
Acids and bases are familiar to the majority of people. But what actually is an acid, and what is a base? Here we discover 3 different definitions of acids and bases, and examine them more closely.
Electrochemistry - as its name implies covers the relationship between electrical energy and chemistry. In this section we cover principles behind how batteries work and also how we can use electricity to drive chemical reactions.
