Diluted hydrochloric acid + Solid magnesium hydroxide → Water + Soluble magnesium chloride

Here's a breakdown:

* Diluted hydrochloric acid: This is the acid, which is a solution of hydrogen chloride (HCl) in water.

* Solid magnesium hydroxide: This is the base, a solid compound with the formula Mg(OH)₂.

* Water: This is a product of the reaction, formed by the combination of hydrogen ions from the acid and hydroxide ions from the base.

* Soluble magnesium chloride: This is the salt formed, a soluble compound with the formula MgCl₂.

This reaction is a classic example of an acid-base neutralization reaction.
