When the strip of pH paper was put in a given solution, the pH paper changed to orange red. The given solution is most likely to be of :
(1)sodium hydroxide (2) hydrochloric acid
(3)sodium bicarbonate (4)ethanoic acid

Academic Chemistry NCERT Class 10

Correct answer: (4) ethanoic acid

Explanation:

From the above image, it is clear that pH paper turns orangish red ion the presence of week acid such as ethanoic acid.
