Answer 2

• As we know that we can change color in the presence of acids and base.

• Hibiscus paper acts as litmus paper. the hibiscus is slightly alkaline.

• It has the ability to change color when mixed with opposite pH substances.

• Hibiscus blue paper gives red color in acidic solution. red color terns into blue in base solution.
• From the given question, we get red color when buttermilk, lemon juice, tamarind water, and vinegar are rubbing on hibiscus paper. other substances have no effect.
