You havebeen provided with three test tubes. One of them contains distilledwater and the other two contain an acidic solution and a basicsolution, respectively. If you are given only red litmus paper, howwill you identify the contents of each test tube?

Question

Answer

Identifying the contents of test tubes using red litmus paper

Materials

Three test tubes

Red litmus paper

Distilled water

An acidic solution (e.g. vinegar)

A basic solution (e.g. baking soda dissolved in water)

Procedure

Label the test tubes A, B, and C.

Add distilled water to test tube A.

Add a small amount of the acidic solution to test tube B.

Add a small amount of the basic solution to test tube C.

Dip a piece of red litmus paper into each test tube.

Observe the color change of the litmus paper.

Observations and Interpretation

If the red litmus paper remains red in test tube A, it indicates that the contents are neutral, i.e. distilled water.

If the red litmus paper turns blue in test tube C, it indicates that the contents are basic.

If the red litmus paper turns red in test tube B, it indicates that the contents are acidic.

Conclusion

Using red litmus paper, we can easily identify the contents of each test tube. The litmus paper turns blue in the presence of a basic solution, red in the presence of an acidic solution, and remains red in the presence of a neutral solution. This simple test can be used in various applications, such as in the field of chemistry and environmental science.

Answer

put the red litmus solution one by one in each test tube , then the only solution which turns the red litmus blue is basic solution

Answer

the red litmus should be dipped in three test tubes. in which test tube it will blue that will be the base and in remaining two test tubes, in which test tube it will turn red that will be acid and the remaining is the distilled water

Answer

if the red litmus paper turns in to Blue then it is basic in nature.if the red litmus paper does not change then we must think either it is acidic are neutral.take three testubes and name it as A,B and C. put the litmus paper in testubes A,B and C.if we put the litmus paper in the first test tube then the colour changes in to Blue. so A testube is clear that it is in  blue. so the other two testubes.Now a drop of basic solution is mixed witha drop of each of the remaining two solutions separately and then thenature of the drops of the mixtures is checked. If the colour of redlitmus turns blue, then the second solution is neutral and if thereis no change in colour, then the second solution is acidic.I hope it is correct only.☺
