Definition of Acids and Bases
In our day to day life we come across various materials both elements and compounds with different characteristics. Some of them are sour in taste, some are salty and others are bitter in taste. On the basis of their properties they can be classified as acids, bases and salt. They have certain definite properties which distinguish these compounds from each other. For example acids are different than the bases and salts. Most of digestive fluids of humans and animals contain acids and are sour in taste. The bitter taste of substances like bitter gourd, cucumber etc is due to the presence of base in them.
Acids: Acids are those chemical substances which are sour in taste.
The term ‘acid’ has been derived from a Latin word acidus, meaning sour. For example, lemon juice, tomato, vinegar, etc., all taste sour. Some common fruits such as oranges, raw mango are sour in taste. This means that they have acids present in them. Acids turn blue litmus red.
