What are the products of neutralizing an acid with a hydroxide?

Explanation:
When an acid is neutralized by a hydroxide, a neutralization reaction occurs: the hydrogen ion (H+) from the acid reacts with the hydroxide ion (OH−) from the base to form water (H2O). The remaining ions—the cation from the base and the anion from the acid—combine to form a salt. So the products are salt and water. For example, HCl + NaOH gives NaCl + H2O, and H2SO4 + 2 NaOH gives Na2SO4 + 2 H2O. Hydrogen gas isn’t produced in this reaction, and producing only water or only a salt would ignore part of what's formed.
