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 ...

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 ...

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 ...

A crash course on the basic differences between acids and bases. A crash course on the basic differences between acids and bases, complete with a classroom-friendly experiment demonstrating the ...

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 ...

Welcome to science world. Now everyone loves a wee bag of chips, don’t they? Maybe a wee pasty or a battered sausage and if you’ve any sense you’ll cover it in a bit of vinegar. But did you know that ...

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 ...
