Rufina [12.5K]

Answer:Salt

Explanation:

In chemistry a salt is produced from a neutralization reaction, when an acid react with a base.

A salt consists of the positive ion (cation) of an acid and the negative ion (anion) of a base.

H+(aq) + Cl-(aq) + Na+(aq) + OH-(aq) -------> Na+Cl-(aq) + H2O(l)

When the water is evaporated, the negatively charged chlorine ions combine with the positively charged sodium ions to form a solid salt.
