Back to all questions 17
Question Three liquids are given to you. One is vinegar, another is a baking soda solution, and the third is a sugar
Can you identify them only using turmeric paper? Explain.
Answer:
Using turmeric paper, we can identify a basic solution but not an acidic or neutral solution. When baking soda solution (basic) is tested, the turmeric paper will turn red. However, both vinegar (acidic) and sugar solution (neutral) will leave the paper yellow, as turmeric paper does not change colour in acidic or neutral solutions. Therefore, turmeric paper can only identify a basic solution.
