What is formed when an acid reacts with a base?

Explanation:
When an acid reacts with a base, a neutralization occurs where the acid’s H+ and the base’s OH− combine to form water, and the remaining ions form a salt. This is why the usual outcome is a salt plus water. For example, NaOH (a base) reacting with HCl (an acid) gives NaCl (a salt) and H2O (water). The other substances listed aren’t produced in a typical acid–base neutralization: oxygen gas would come from other redox reactions, carbon dioxide from reactions with carbonates, and hydrogen gas from certain metal–acid reactions or other processes.
