Question

8. What is insulator?
9. What is neutralisation reaction?
10. What is an acid-base indicator ?​

Answer 1

Answer:

8. a material or device used to prevent heat, electricity or sound from escaping from something

9. In chemistry, neutralization or neutralisation (see spelling differences) is a chemical reaction in which acid and a base react quantitatively with each other. In a reaction in water, neutralization results in there being no excess of hydrogen or hydroxide ions present in the solution.

10. Acid–base indicators are generally weak protolytes that change color in solution according to the pH. The acid–base equilibrium of a weak acid type of indicator (HI) in water can be represented as. [I] The acid, HI, and the conjugate base, I−, have different colors.

Answer 2

• An insulator is any object which does not conduct heat or electricity
• Neutralisation reaction is one in which the acid and base are balanced and salt is evolved (with heat), this solution is neither acidic nor basic in nature
• An acid base indicator helps us to identify whether or not any substance/compound/solution is acidic or basic in nature.
