    · Acids

    Any substance that tends to change color or taste sour when mixed in water is said to have acidic nature. When seen in the chemical lab, we can identify whether a substance is acidic or not by checking if it changes the color of litmus paper from blue to red. In other cases, the acid reacts with other metals to liberate hydrogen, with bases to form salts and also act as catalysts in many chemical reactions. Examples:

    Carboxylic acid, sulphonic acid, and many more.

    · Bases

    Any substance that tends to change color or appears slippery in touch or taste bitter when mixed in water is said to have basic nature. When seen in the chemical lab, we can identify whether a substance is basic or not by checking if it changes the color of litmus paper from red to blue. In other cases, reacts with acids to form salts and also act as catalysts in many chemical reactions. Examples:

    Sodium, calcium, and many more.

    · Salts

    Salt is basically a product formed by the combination of acids and bases. It in general, consists of a positive and a negative ion namely cation and anion respectively. This term is also used commonly in our day-to-day life in the form of table salt.

    · Key differences between acids, bases and salts

    1. Difference in their pH level is dramatically different and specified.

    2. They can be distinguished easily by the litmus paper test, and in some cases, by their physical appearance.

    3. These can be also distinguished on the basis of their chemical formulas (due to presence of ions).

    I hope this answer helps!😊
