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 ...

The 1970’s was the decade that illuminated the threat of acid rain to the citizens of the US. It had been known to exist several years before, but the sources of the problem did their best to suppress ...

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 ...

Chemists have long known that catalytic Lewis acidic and Lewis basic sites on metal and metal oxide surfaces help spark a range of reactions that are important in industrial chemical and fuel ...

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 ...

Neutralisation is the reaction of an acid with a base that results in the pH moving towards seven. It is a useful process that occurs in everyday life such as in the treatment of acid indigestion and ...

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 ...
