Compounds are classified as acids, bases, and salts. Introduction to Acids, Bases and Salts: Compounds are classified as acids, bases, and salts based on the Arrhenius definition, and as acids or ...

Acids are chemical compounds that will ionize in water having a hydrogen ion (H+) active greater than that of water. Acids can give up a proton and they are of two types, it is strong acids and weak ...

Several theories have been developed to explain the behaviour of acids and bases. The most notable theories include the Arrhenius concept, the Brønsted-Lowry theory, and the Lewis concept. In the ...

Introduction You might have done experiments with well-labeled acids and bases in school, but have you ever wondered whether a certain food or chemical around the house is an acid or a base? You can ...

The pH scale shows how acidic a substance is. Learn what pH means and how it is measured in this KS3 chemistry guide from BBC Bitesize. Neutralisation reactions Acids and alkalis react together in ...

A neutralisation reaction is one in which an acid reacts with a base to form water. A salt is also formed in this reaction. Bases are metal oxides, metal hydroxides and metal carbonates. In the ...

An acid-base indicator is a substance that changes color as the pH of the solution changes. Indicators work because they are weak acids which when in solution, exist in equilibrium with their ...
