Concept:A strong acid reacts completely with a strong base to form a neutral salt, also called a normal salt.Explanation:A strong acid donates H+ ions while a strong base provides OH− ions.They neutralize each other fully, leaving no excess acid or base in the solution.The resulting salt is neither acidic nor basic in nature.Such salts are known as normal salts or neutral salts.Example: HCl+NaOH→NaCl+H2O.Here, NaCl is a normal salt because it is formed by complete neutralization.Answer:A. normal
