Answer 1

Acids and Bases:

Acids

Acids are substances that taste sour and are corrosive in nature.

It turns blue litmus paper to red.

These substances are chemically acidic in nature.E.g.:-orange juice, curd, vinegar, hydrochloric acid etc.

Bases

Bases are substances that, in aqueous solution, are slippery to the touch and bitter in taste.

It turns red litmus paper to blue.

These substances are chemically basic in nature. Eg:- soap, ammonium hydroxide, calcium hydroxide, etc.

Neutralisation Reaction

When an acid and base react with each other to form a salt, water and heat then such reaction is known as neutralisation reaction.

In this reaction, the acidic and basic nature of the acid and base respectively are destroyed.

The reaction between hydrochloric acid and sodium hydroxide is a classic neutralisation reaction where sodium chloride is formed.

HCl+NaOH→NaCl(salt)+H2O

Salts

Salts

Salt is the product formed from the neutralisation reaction of acids and bases.

In the reaction between hydrochloric acid and sodium hydroxide the salt formed is sodium chloride.

HCl+NaOH→NaCl+H2O

Salt can be acidic, basic or neutral in nature.

Substances, which are used to test whether a substance is acidic or basic are called indicators.

Answer 2

Explanation:

${\fbox{\pink{Summary~of~Acidic~and~Basic~Salts}}}$

$\tt\orange{Acid~salts~are~the~converse~of~basic~salts}$$\tt\red{; they~ are~formed~in~the~neutralization~reaction}$between a strong acid and a weak base. The conjugate acid of the weak base makes the salt acidic. ... The ammonium ion contains a hydrolyzable proton, which makes it an acid salt.
