Question

A student has four solutions among which one is acidic in nature. She wants to identify the acidic solution using a litmus paper. Which of these observations would help identify the acidic solution?​

Answer 1

If the Blue litmus paper turns red in any of the solutions then its an acidic solution.

Answer 2

A student has four solutions among which one is acidic in nature. She identifies the acidic solution using a litmus paper and the litmus paper turns red.

• Litmus paper is one of the ways to identify the pH of a solution.
• The pH value of a solution indicates whether the solution is acidic or basic.
• If the litmus paper turns red when brought in contact with the solution, it is acidic in nature.
• If the litmus paper turns blue when brought in contact with the solution, it is basic in nature.
• If the litmus paper turns violet when brought in contact with the solution, it is neutral in nature.
