Class 7 science chapter 5 acids, bases and salts ncert solutions. class 7 ncert solutions for science chapter 5 includes all the intext and exercise questions. all these questions are solved by experts with a detailed explanation that will help students complete their assignments and homework. question 1: state differences between acids and bases. Q.5.describe the process of neutralisation with the help of an example. ans.the reaction between an acid and a base is known as neutralisation. salt and water are produced in this process with the evolution of heat. antacids like milk of magnesia (magnesium hydroxide), baking soda, etc. which contain a base are used for reducing acidity in. The resulting solution is a neutral solution. hydrochloric acid (hcl) sodium hydroxide (naoh) → sodium chloride (nacl) water (h 2 o) heat. in this reaction, the hydrogen ions from the acid reacts with the hydroxide ions of the base to from water and salt is formed. question 6.
