Question: 1 / 400

What products are formed during a neutralization reaction?

Salt and oxygen

Salt and carbon dioxide

Salt and water

In a neutralization reaction, an acid reacts with a base to produce a salt and water. This is a key concept in acid-base chemistry. During the reaction, the hydrogen ions (H⁺) from the acid combine with the hydroxide ions (OH⁻) from the base to form water (H₂O). The remaining ions from the acid and base then combine to form the salt.

For instance, if hydrochloric acid (HCl) reacts with sodium hydroxide (NaOH), the products will be sodium chloride (NaCl), which is the salt, and water. This generalization applies to all neutralization reactions, making salt and water the consistent products formed.

Other options involve different substances that do not typically result from a neutralization process. Therefore, the formation of salt and water is a hallmark of neutralization reactions, making it the correct answer.
