NCERT Solutions for Class 7 Science Chapter 5 - Acids, Bases and Salts

 

NCERT Solutions for Class 7 Science Chapter 5 - Acids, Bases and Salts: You know that Curd, lemon juice, orange juice and vinegar taste sour. These substances taste sour because they contain acids. The chemical nature of such substances is acidic. The word acid comes from the Latin word acere which means sour. The acids in these substances are natural acids. Now you must be thinking that what about baking soda? Does it also taste sour? If not, what is its taste? Since it does not taste sour it means, that it has no acids in it. It is bitter in taste. If you rub its solution between fingers, it feels soapy. Generally, substances like these which are bitter in taste and feel soapy on touching are known as bases. The nature of such substances is said to be basic.
