When is salt form?

When an acid reacts with a base, it results in the formation of salt and water. This process is known as neutralisation. The general equation for a neutralisation reaction is:

Acid + Base → Salt + Water

For example, when hydrochloric acid (HCl) reacts with sodium hydroxide (NaOH), it forms sodium chloride (NaCl) and water (H2O).

HCl + NaOH → NaCl + H2O

In this reaction, hydrochloric acid is the acid, sodium hydroxide is the base, sodium chloride is the salt, and water is the product of the reaction.
