Reaction:
2HCl(aq) + MgO(s) → MgCl₂(aq) + H₂O(l)
Explanation:
* Hydrochloric acid (HCl) is a strong acid, meaning it readily donates a proton (H+).
* Magnesium oxide (MgO) is a basic oxide, meaning it readily accepts a proton (H+).
When HCl and MgO react:
* The hydrogen ions (H+) from the HCl combine with the oxide ions (O2-) from the MgO to form water (H₂O).
* The magnesium ions (Mg2+) from the MgO combine with the chloride ions (Cl-) from the HCl to form magnesium chloride (MgCl₂), which dissolves in water.
Products:
* Magnesium chloride (MgCl₂) is a salt that remains dissolved in the solution.
* Water (H₂O) is formed as a byproduct.
Overall, the reaction is an example of a neutralization reaction, where an acid and a base react to form a salt and water.
