Question

you have been providedwith three test tubes one of them contain distlled water the other two contain an acidic solution and abasic solution ,respectively .if you are given only red litmus paper .how will you identify the content of each test tubes​

Answer 1

Answer:

inA the litmus paper occurs no change

inB to the litmus paper occurs no change

but in c as the solution is basic when it is dipped by red litmus paper then the paper changes into blue colour hence we can conclude that when red litmus paper is dropped in a basic solution then changes into blue colour

Explanation:

hope you could get the concept that

1 when red or blue litmus paper is dipped in a neutral solution like distilled water then no change occurs in the litmus paper

2 if you dip a blue litmus paper in a basic solution then nothing change occurs in the litmus colour ; but when you drop blue litmus paper in acid then it changes into red colour

3 if YouTube per a red litmus paper in acidic solution then it changes to blue colour this is the interference

Answer 2

Answer:

Hey Mate

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.

Hope this helps You!!
