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:
Add few drops of solution from all three test tubes on the red litmus paper separately. The solution which turns red litmus to blue contains basic solution. Use this blue litmus paper to test the solutions in other two test tubes. The solution from the test tube which turns blue litmus paper to red will be the acidic solution and solution of the test tube which do not change either red or blue litmus paper contain water
Answer:
If the colour of red litmus paper turns blue then the solution is is basic.If there is no colour change then its either basic or neutral
Explanation:
let us mark the three test tubes A,B,C. Drop a solution in test tube A to red litmus paper. Repeat the same with other solution B,C. If either of them turns the red litmus blue then it is basic.now the remaining solution are acidic or neutral. now drop the basic solution in the both the test tube. if solution turns blue the the solution is neutral. If no colour change then its acidic solution,
