The pH scale measures the acidity or alkalinity of a substance, ranging from 0 to 14, with values below 7 representing acidity, above 7 representing alkalinity, and 7 representing neutrality.

Watch this video to see how a salt can be produced in the lab by neutralising sulfuric acid with a metal carbonate, in this case copper carbonate. Here are some ways neutralisation is used: Farmers ...

A salt is a compound formed from an acid by the replacement of the hydrogen in the acid by a metal. Therefore, it is formed when acids react with bases. Generally, we represent salt as Sodium Chloride ...
