A student thinks that only water is formed in an acid-base reaction. Why is this idea incomplete?

Answer and explanation

Correct answer: Because acid and base form both salt and water

The governing concept is neutralisation. In a typical acid-base reaction, hydrogen ions from the acid combine with hydroxide ions from the base to form water, while the remaining positive and negative ions combine to form a salt. For example, HCl + NaOH → NaCl + H₂O. Thus water is only one product; salt is also formed. The other options contradict the reaction, so B is correct.
