Which of the following is true about the results of a neutralization reaction?
A. An acid and a base form water and salt.
B. Water reacts with a base to form the hydroxide ion.
C. Water reacts with an acid to form the hydronium ion.
D. An acid and a base dissociate into their ions.
D?
I don't think there is an answer. A is true most of the time but not always. It depends, somewhat, upon how acids and bases are defined. D is a true statement but that isn't neutralization. B and D are true, also, but those aren't neutralization reactions.
Actually, none of the above answer choices are totally correct. Neutralization reactions are too often taught as acid + base => salt + water. There are neutralization reactions the do not produce water. Example: NaCN + HOAc => NaOAc + HCN. The acidic hydrogen from acetic acid is transferred to the cyanide ion because it is a stronger conjugate base than the acetate ion.
No, option D (An acid and a base dissociate into their ions) is not true about the results of a neutralization reaction. The correct option is A: An acid and a base form water and salt. In a neutralization reaction, an acid and a base react together to form water and a salt. The salt is formed when the positive ion from the base combines with the negative ion from the acid.
The correct answer is A. An acid and a base form water and salt.
In a neutralization reaction, an acid reacts with a base to produce water and a salt. The reaction involves the transfer of protons (H+ ions) from the acid to the base, resulting in the formation of water (H2O) and the combination of the remaining ions from the acid and the base to form a salt.
To determine the correct answer, we need to understand the concept of neutralization reactions and the products they produce.
To solve this question, you can approach it by eliminating the answer choices one by one:
Option B states that water reacts with a base to form the hydroxide ion. However, this is not the correct product of a neutralization reaction.
Option C suggests that water reacts with an acid to form the hydronium ion (H3O+). However, this is not the correct product of a neutralization reaction.
Option D states that an acid and a base dissociate into their ions. While this is true for acids and bases in general, it does not accurately describe the specific products of a neutralization reaction.
Option A correctly states that an acid and a base form water and salt, which is the characteristic feature of a neutralization reaction.
Therefore, the correct answer is A. An acid and a base form water and salt.
