Not necessarily be a chemical reaction.
Dissolution of solids are generally physical properties, because if the solvent is removed, then we can get the solid back (in most of the cases).
Magnesium is a chemical element, a solid metal not a reaction.
Solid solution
A reaction doesn't occur.
a precipitate
A chemical reaction is categorized as a precipitation reaction when it involves the formation of a solid precipitate. This occurs when two aqueous solutions react to produce an insoluble product that separates out as a solid. The solid precipitate typically forms due to the combination of ions from the different solutions.
Sodium chloride is dissociated in water: NaCl---------------------Na+ + Cl-
If the solid material dissolves in the clear colorless liquid, the chemical reaction is most likely a dissolution process where the solid breaks down into its constituent ions or molecules and disperses evenly in the liquid. This process is typically a physical change rather than a chemical reaction, as no new substances are formed. If there is a chemical reaction occurring, it would depend on the specific identities and properties of the solid material and the clear colorless liquid.
The new solid formed after a chemical reaction is often called the precipitate but not necessarily.
Magnesium is a chemical element, a solid metal not a reaction.
when the reaction done between solid and liquid interface is called physio-chemical reaction.
Precipitates are solid materials formed from the reaction of two liquids to create a solid that no longer dissolves in the solution. They can vary in color, size, and shape depending on the reaction conditions. Precipitates are typically insoluble in the solvent and can be separated through filtration.

A "precipitate".
To determine the presence of a precipitate in a chemical reaction, one can look for the formation of a solid substance that appears cloudy or settles at the bottom of the reaction mixture. This solid substance is called a precipitate and indicates that a chemical reaction has occurred.
Vapor is not a chemical reaction itself. It is the gaseous state of a substance that was previously in liquid or solid form. The process of creating vapor from a liquid or solid can involve a physical change (such as evaporation) rather than a chemical reaction.
A solid formed from liquid reactants during a chemical reaction is called a precipitate. This occurs when two soluble reactants mix and a solid compound is formed that is insoluble in the reaction medium.
