paper and pH paper is useful to distinguish
between ethanoic acid and hydrochloric acid.
Justify your answer.​

Answer 1

Answer:pH paper is useful.

Explanation:Because both ethanoic and Hydrochloric acid ate acids and turns blue litmus paper red. Therefore, there will be no difference.

But if we use pH paper the colour would be different due to the difference in acidity .

Answer 2

Answer:

pH paper is used as litmus paper only indicates whether a substance is acidic or basic.So we can not distinguish. But pH on the other hand tells how strong or weak an acid or base is.

ethanoic acid being a weak acid than HCl we can distinguish between them.
