Answer
Litmus paper turns red in acidic solutions.
Litmus paper turns red in acidic solutions.
Answer for screen readers
Litmus paper turns red in acidic solutions.
More Information
Litmus paper is a type of pH indicator used to test materials for acidity or basicity. Blue litmus paper specifically turns red in the presence of an acid, helping to determine whether a solution is acidic.
Tips
A common mistake is confusing the colors for acids and bases. Remember that acids turn blue litmus paper red.
