Answer 1

A solution turns blue litmus red. Its pH is likely to be 5.

Explanation:

A solution that turns blue litmus paper red is acidic, indicating the presence of hydrogen ions. The pH scale ranges from 0 to 14, where values below 7 indicate acidic solutions, 7 is neutral, and values above 7 indicate basic solutions. Since 5 is the only option that is less than 7, it is the likely pH of this solution.
