Question

Please write preface for the topic of acid base and salt

Answer 1

Acids, bases and salts are three main categories of chemical compounds. These have certain definite properties which distinguish one class from the other. The sour taste of many fruits and vegetables, lemon for instance, is due to various types of acids present in them. The digestive fluids of most animals and humans also contain acids. The word 'acid' is derived from a Latin word, which means "sour". The acids we use in the laboratory are stronger acids like hydrochloric acid and sulphuric acid. Strong acids are corrosive and can burn your skin. Bases on the other hand are the chemical opposites of acids. They are bitter in taste and soapy to touch. Sea water and detergents are some examples of substances that are basic. Many bases are oxide or hydroxide compounds of metals.
