Question 12

Acid + base → water + salt

The general reaction for neutralizing acids and bases is represented as acid plus base yielding water and salt. This fundamental chemical reaction illustrates the process of neutralization.

A) Acid + base → water + salt

This option correctly defines the neutralization reaction. When an acid reacts with a base, the products formed are water and a salt. This reaction is essential in various chemical processes and is the classic representation of acid-base neutralization.

B) Base + water → acid + salt

This option is incorrect as it suggests that a base reacts with water to form an acid and salt, which does not accurately reflect the neutralization process. Instead, neutralization involves the direct reaction of an acid and a base, not the generation of an acid from a base in the presence of water.

C) Salt + water → acid + base

This choice is also incorrect. It implies that mixing salt and water can produce an acid and a base, which contradicts the principles of acid-base chemistry. Neutralization does not occur in this manner, as it requires the direct interaction of an acid and a base.

D) Acid + base → water + salt

This option is the same as the correct answer, reinforcing the definition of the neutralization reaction. It succinctly captures the essence of the reaction between an acid and a base, confirming its accuracy.

Conclusion

The correct answer, "Acid + base → water + salt," clearly encapsulates the process of neutralization, a fundamental concept in chemistry. All other options fail to represent the correct reaction dynamics involved in acid-base interactions, either misrepresenting the reactants or incorrectly describing the products formed. Thus, option D is definitively the right choice for understanding neutralization reactions.
