Final answer:
When acids and bases neutralize each other, the amounts of H+ and OH− become equal, water is produced, and a salt, which is an ionic compound, is formed. Therefore, all the statements are true.
Step-by-step explanation:
The question is asking about the result of acid and base neutralization. During this process, several things happen:
- The amount of H+ (acidic ions) and OH− (basic ions) combine in such a way that they are in equal amounts, leading to neutralization.
- As a result of the neutralization, water (H2O) is often produced as one of the products.
- Furthermore, a salt is formed, which is the ionic compound made from the cation other than H+ from the acid and the anion other than OH− from the base.
Therefore, the correct answer to what is true when acids and bases neutralize each other would be d) All of the above.
