Fynlain why.​

Answer 1

Answer:

${\huge{\sf{\green{\underline {\underline {Answer }}}}}}$

Reactions between an acid and a base are known as neutralization reactions. On mixing an acid with a base, i.e., in neutralization reaction, salt and water are obtained as products. Also, energy is evolved during the process. The general equation for the neutralization reaction is represented as:

Acid + Base → Salt + Water

For example, when sodium hydroxide (NaOH) is treated with hydrochloric acid (HCl), then a salt, i.e., sodium chloride (NaCl) and water (H2O) are obtained. The chemical equation for the neutralization reaction .....

Answer 2

Answer:

Describe an activity in which neutralization of hydrochloric acid takes place with sodium hydroxide, using phenolphthalein as an indicator. ... The process due to which an acid completely reacts with a base with the evolution of heat to form salt and water as the products is called Neutralisation
