Question

Answer

Basic Solution for Acid-Base Reactions:

A: Red litmus turns blue

An acid turns blue litmus paper red. This indicates that the substance is acidic.

Red litmus paper is red when it is neutral or basic. If it turns blue, it indicates the presence of an acid.

B: Red litmus turns green

In the presence of a base, red litmus paper can turn green. This is a result of the alkaline nature of the substance.

Green litmus paper is green when it is neutral or acidic. If it turns green, it indicates the presence of a base.

C: Blue litmus turns red

A base turns blue litmus paper red. This indicates that the substance is basic.

Blue litmus paper is blue when it is neutral or acidic. If it turns red, it indicates the presence of a base.

D: No reacting

If no change is observed in the litmus paper, it implies that the substance is neutral.

Neutral substances do not have any effect on litmus paper, causing no change in the color of the paper.

In summary, the basic solution turns red litmus blue, red litmus green, and blue litmus red. If no reaction occurs, it indicates that the solution is neutral.

Answer

Red litmus is the paper manufactured by dye and which is red in colour. This paper is used to test acidic and basic nature of the solution. On solution being basic, red litmus turns blue in colour.

Answer

Introduction:
In this question, we are given a basic solution and we need to determine its effect on red and blue litmus paper. The options given are: a) Red litmus turns blue, b) Red litmus turns green, c) Blue litmus turns red, and d) No reaction.

Explanation:
To understand the effect of the basic solution on litmus paper, we need to know the properties of litmus paper and how it reacts to different solutions.

Litmus Paper:
Litmus paper is a type of indicator paper that is commonly used to test the acidity or basicity of a solution. It is made from a mixture of natural dyes extracted from lichens. Litmus paper comes in two colors: red and blue.

- Red Litmus Paper: Red litmus paper is used to test whether a solution is acidic or neutral. It remains red in acidic and neutral solutions, but turns blue in basic solutions.

- Blue Litmus Paper: Blue litmus paper, on the other hand, is used to test whether a solution is basic or neutral. It remains blue in basic and neutral solutions, but turns red in acidic solutions.

Effect of Basic Solution on Litmus Paper:
Now, let's apply this knowledge to the given basic solution and determine its effect on litmus paper.

- Option 'A': Red litmus turns blue: This option is correct. Since the given solution is basic, it will turn red litmus paper blue. This is because basic solutions have a higher concentration of hydroxide ions (OH-) which can react with the red litmus paper and change its color to blue.

- Option 'B': Red litmus turns green: This option is incorrect. Basic solutions do not turn red litmus paper green. The only color change that occurs with red litmus paper and basic solutions is from red to blue.

- Option 'C': Blue litmus turns red: This option is incorrect. Basic solutions do not turn blue litmus paper red. The only color change that occurs with blue litmus paper and basic solutions is from blue to no reaction.

- Option 'D': No reaction: This option is incorrect. Basic solutions do react with litmus paper, specifically red litmus paper, and cause a color change from red to blue.

Conclusion:
In conclusion, the correct answer is option 'A': Red litmus turns blue. Basic solutions turn red litmus paper blue due to the presence of hydroxide ions.
