The correct answer is option (4) All of these.

Explanation:

What is litmus paper?

• Litmus paper is created by dipping a piece of paper in litmus solution and serves as an indicator for acid or base.
• There are two types of litmus paper:

1. Blue Litmus paper: If blue paper is turned to red, that means the solution is acidic.
2. Red Litmus paper: If red paper is turned to blue, that means the solution is basic.

How is turmeric used as an acid-base indicator?

• When turmeric reacts with the base, it turns a deep red color.
• If we add acid to this red-colored solution, turmeric returns to its yellow color.

What is Gudhal?

• Gudhal is also known as Hibiscus.
• Hibiscus solution is used as an acid-base indicator as it contains anthocyanin as a color pigment.
• If the Gudhal solution turns red, it indicates the presence of acid.
• And if the Gudhal solution turns a dark green color (blackish green), then it indicates the presence of base.

So, from the above discussion, it is proved that litmus paper, turmeric and gudhal all three of these are used as acid-base indicators.
