In which reaction are both salt and water definitely formed?

Answer and explanation

Correct answer: Reaction of acid and base

The reaction between an acid and a base is called neutralisation. In the usual neutralisation reaction, the hydrogen ions from the acid combine with hydroxide ions from the base to form water, while the remaining ions form a salt; for example, HCl + NaOH → NaCl + H₂O. Metal oxidation usually forms an oxide, hydrogen combustion forms water alone, and dissolving salt is not a new formation reaction. Hence A is correct.
