B acid + base → water + salt
Explanation:
The best equation that represents a neutralization reaction is:
acid + base → water + salt
In a neutralization reaction, an acid reacts with a base to produce salt and water only.
Here, hydrogen combines with hydroxide to form water.
Titration is usually used to carry out this reaction in the laboratory.
