Theory:

When an acid and a base are combined, a chemical reaction occurs. This process is called neutralisation. The reaction mixture produces heat during neutralisation; hence, it is an exothermic reaction.
In neutralisation reaction, a new substance is formed, which is known as salt. The salt produced here can be either acidic, basic or neutral.

Acid+BaseSalt+Water+Heat
 
The reaction between the hydrochloric acid and sodium hydroxide gives salt and water as a product. It is one example for neutralization reaction.
 
HCl+NaOHNaCl+H2O+Heat

Acid-base reaction
 
Similarly, other acids also produce salt and water when reacting with the base. Let us see some examples of the reaction of acids with sodium hydroxide (\(NaOH\)).
 
H2SO4+NaOHNa2SO4  +H2OSulphuricSodiumacidsulphate
 
HNO3+NaOHNaNO3+H2ONitricSodiumacidnitrate
 
CH3COOH+NaOHCH3COONa+H2OAceticSodiumacidacetate
