No observable change is noticed when dilute hydrochloric acid is added to :
(1)sodium hydroxide solution (2)sodium carbonate solution
(3) blue litmus solution (4) zinc metal

Correct answer: (1) sodium hydroxide solution

Explanation: When an acid (dilute hydrochloric acid) reacts with a base (sodium hydroxide), they neutralize each other to form salt and water. Hence, no observable change occurs.
