Is the chemical reaction between magnesium metal and hydrochloric acid solution an acid base reaction?

No

Explanation:

The chemical reaction between magnesium metal and hydrochloric acid solution is not an acid - base reaction.

An acid - base reaction involves an acid and base to produce salt and water.

This reaction is called a neutralization reaction. An acid is a substance that produces excess hydroxonium ions in solutions. A base produces excess hydroxyl ions in solution. When acids and base combines, the main product is a salt in water solution.

The gas would begin to expand, and eventually the can would burst or explode.

Solubility would be your answer.
