Answer 2

Answer:

If a drop of an unknown substance turns blue litmus paper pink, but does not change pink litmus paper, the substance is an acid.

Explanation:

• A natural soluble dye from lichen has been used to treat filter paper to make "litmus paper." Paper known as "Litmus" yields a result that can be used as a pH indicator.
• The primary purpose of litmus is to determine whether a solution is acidic or basic. Blue litmus paper turns red under acidic conditions, while red litmus paper turns blue under basic or alkaline conditions, in a pH range of 4.5-8.3 at 25 °C (77 °F). Neutral is purple litmus paper.
• If a drop of an unknown substance turns blue litmus paper pink, but does not change pink litmus paper, the substance is an acid .
