you have been provided with three test tubes,one of them contains distilled water and the other two contain an acidic solution and a basic solution, respectively.if you are given only red litmus paper ,how will you identify the contents of each test tube
Answers
Answer:
We can identify the content in each of the test tubes using red litmus paper. This can be done by noticing the colour change of the red litmus paper.
On litmus paper, few drops of the three solutions in the test tubes are added separately.
The solution which turns red litmus paper to blue contains a basic solution.
Divide the obtained blue litmus paper into two parts.
The solution from the test tube which turns blue litmus paper to red will be the acidic solution.
Solution of the test tube which do not change either red or blue litmus paper contain water.
