Important Topic for NCERT Solutions for Class 7 Science Chapter 5

Acids and Bases 

The first part of Class 7 Science NCERT Chapter 5 describes acids and bases. Acids and bases are two unlike materials available all around us. They can be certainly found or formed through chemical reactions. 

Acids and Bases Release Ions when Dissolved in Water 

Acids are materials that release H+ ions when they are saluted in water. On the other hand, bases are the materials that release OH- ions when saluted in water. Knowledge of acids and bases are used to define the pH level and acid-base reactions.

It is significant to learn about them as they are very much important for the numerous environmental phenomena. They also help us in preserving the pH level of the human body as well as the manufacturing of several notable products. 

Coming on to the significance of materials like acids and bases for humans, it can be said that they help us in the proper regulation of blood and digestion of food in our body. Also, for the proper functioning of kidneys, lungs, and other main organs of our body, we need diverse types of acids or bases or sometimes a combination of both the materials. 

Natural Indicators 

You must understand what are natural indicators for preparing the NCERT Solutions for Class 7 Science Chapter 5 correctly. Natural indicators are the indicators that are available around us and are used to define whether a substance is acidic or basic.

Natural indicators also have basic or acidic properties. Some of the basic natural indicators around us include broccoli, sweet almond, beer, walnuts, eggplant, prawns and mussels et al. All these naturally occurring materials have the properties of a base. They have a pH level of more than 7. Acidic natural indicators around us are apple juice, beetroot, Green tea, Orange, tomato, cherries, bananas, apricots, and many others. 


In this part of NCERT Solutions for Class 7 Science Chapter 5, the process of neutralization is explained in detail. The natural phenomenon of neutralization is also mentioned. Neutralization is a type of reaction between an acid and a base and results in the formation of salt and water. There are four types of reactions that take place between Acid and a base. These are generally based on the deliberation of an Acid or a base.

In general, there are many circumstances when Acid and base reaction takes place. We don’t realize them but they are essential in our daily survival and are a part of our normal lives. 

  • The first use is the treatment of wasp’s sting; 
  • The second most common use is to get relief from the acidity of gastric issues.
