When proper amounts of an acid and a base are mixed, which reaction mainly occurs?
Answer and explanation
Correct answer: Neutralisation
The reaction between an acid and a base in suitable amounts is called neutralisation. 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. Option A is therefore correct. This is not decomposition or a simple combination without salt; formation of salt and water is the defining result.
