When Ba(OH)2(aq) and H2SO4(aq) are mixed, what type of reaction occurs?

Explanation:
Acid-base neutralization is at play here. A strong base (Ba(OH)2) donates hydroxide ions, while a strong acid (H2SO4) provides protons. The H+ and OH- combine to form water, and the remaining ions (Ba2+ and SO4^2−) pair to give the salt BaSO4, which precipitates. This pairing of an acid with a base to produce water and a salt is the defining feature of a neutralization reaction.
