The different colours of litmus in acidic, neutral and basic solutions are, respectively.

Options

A. Red, orange and blue
B. Blue, violet and red
C. Red, colourless and blue
D. Red, violet and blue

Answer

To answer the question regarding the different colors of litmus in acidic, neutral, and basic solutions, we can follow these steps:

### Step 1: Understand Litmus Paper
Litmus paper is a pH indicator used to test the acidity or basicity of a solution. It comes in two colors: red and blue.

### Step 2: Color Change in Acidic Solution
When red litmus paper is placed in an acidic solution, it remains red. Conversely, blue litmus paper turns red when placed in an acidic solution. Therefore, in an acidic solution, the color of litmus is:
- **Red** (for blue litmus paper).

### Step 3: Color Change in Basic Solution
When red litmus paper is placed in a basic solution, it turns blue. Blue litmus paper remains blue in a basic solution. Therefore, in a basic solution, the color of litmus is:
- **Blue** (for red litmus paper).

### Step 4: Color Change in Neutral Solution
In a neutral solution, neither red nor blue litmus paper changes color. Both types of litmus paper remain unchanged. Therefore, in a neutral solution, the color of litmus is:
- **Purple/Violet** (indicating neutrality).

### Conclusion
Thus, the different colors of litmus in acidic, neutral, and basic solutions are:
- **Acidic Solution**: Red
- **Neutral Solution**: Violet
- **Basic Solution**: Blue

### Final Answer
The different colors of litmus in acidic, neutral, and basic solutions are, respectively: **Red, Violet, Blue**.
