What color does litmus paper turn in acidic conditions?

In acidic conditions, litmus paper turns red or pink. Litmus paper is a common pH indicator that is used to determine whether a solution is acidic or basic. When the paper comes into contact with an acidic solution (typically with a pH less than 7), it undergoes a chemical reaction that causes the color to change to red or pink, indicating the presence of acidity. This property makes litmus paper a valuable tool for quickly assessing the pH level of a solution in various settings, including laboratories and educational environments. The other colors associated with the other options do not accurately represent the reaction of litmus paper in acidic conditions; for instance, it turns blue in basic conditions, which is why they do not apply here.
