Question :
You are given three test tubes. These three test tubes contain distilled water, acidic and basic solutions, respectively. Only red litmus paper is available to identify what is there in each test tube. How will you separate what is in each of the three test tubes?Submitted on 28/8/2024 | Answered by Vandana RanaAnswer :
We can identify the content in each test tube using red litmus paper.It can be done by noticing the colour change of the red litmus paper.
The three solutions in the test tubes are poured separately onto litmus paper.
1.The solution that changes red litmus to blue contains a basic solution.
2. Divide the formed blue litmus paper into two parts.
3. The solution from the test tube, which turns blue litmus paper red, will be the acidic solution.
4. The solution of the test tube, which does not change either red or blue litmus paper, contains water.
