The three situations in which ionic reactions go to completion is formation of a gas, a precipitate and a slightly ionized product.
<h3>What are ionic reactions?</h3>
It indicates the flow of electrons and, therefore, the bonds broken and formed in the course of the reaction. It is theoretical, it can be corroborated by experiments, but sometimes there is no consensus on the mechanism by which a certain reaction occurs.
Chemical reactions are the result of the transformation that occurs in substances, where atoms rearrange themselves, modifying their initial state. Thus, chemical compounds undergo changes generating new molecules. In turn, the atoms of the elements remain unchanged.
