***A*** ∻Key Concept∻ ⚹Neutralization Reaction⚹ ∻Explanation∻ ⚹A neutralization reaction occurs when an acid reacts with a base to produce water and a salt. In option (A), $ \mathrm{Ca}(\mathrm{OH})_{2} $ (a base) reacts with $ \mathrm{H}_{2} \mathrm{SO}_{4} $ (an acid) to produce $ \mathrm{H}_{2} \mathrm{O} $ (water) and $ \mathrm{CaSO}_{4} $ (a salt).⚹◊What is the general chemical equation for a neutralization reaction in aqueous solution?⍭ Generate me a similar question◊
