Detailed Solution

Magnesium Oxide and Hydrochloric Acid Reaction

When magnesium oxide (MgO) reacts with hydrochloric acid (HCl), a neutralization reaction takes place. This is a classic acid-base reaction where MgO (a basic oxide) reacts with HCl (a strong acid) to form:

Magnesium chloride (MgCl₂) – a soluble salt
Water (H₂O) – formed as a result of neutralization

Balanced chemical equation:

MgO + 2HCl → MgCl₂ + H₂O

This reaction is exothermic and is commonly used in laboratory preparations of magnesium chloride.
