ACID definition: a compound usually having a sour taste and capable of neutralizing alkalis and reddening blue litmus paper, containing hydrogen that can be replaced by a metal or an electropositive group to form a salt, or containing an atom that can accept a pair of electrons from a base.
In 1661 Robert Boyle summarized the properties of acids as follows. 1. Acids have a sour taste. 2. Acids are corrosive. 3. Acids change the color of certain vegetable dyes, such as litmus, from blue to red. 4. Acids lose their acidity when they are combined with alkalies.
An acid and alkali will neutralise each other and produce a salt and water. This is called a neutralisation reaction. The name of the salt produced can be worked out from the names of the acid and the ...
