Answer:
On the basis of the chemical property of compounds, it has been divided into three groups
Acids, bases and salts where acids and bases combined to form salts. Acid-base chemistry plays an important role in chemistry because every chemical reaction can be classified as an acid-base reaction.
On defining acids and bases so many concepts came forward for the explanation of what acid is and what is a base. Mainly three concepts are there for acids and bases they are Lewis concept, Arrhenius concept and Bronsted-Lowry concept.
Acid-base chemistry is applicable both in a laboratory and as well as in biological level, that means acids are present in the human body also. This chapter comprises of an introduction to the fundamentals of acid-base chemistry, their reaction and uses.
