Answer 1

Describe an activity in which neutralization of hydrochloric acid takes place with sodium hydroxide,using phenolphthalein as an indicator.

Ans. The process due to which an acidcompletely reacts with a base with the evolution of heat to form salt and water as the products is called Neutralisation.

Answer 2

Answer:

Neutralization 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.

HCl+NaOH----- NaCl+H2O.

The colour of phenolphthalein will not change.
