Question

How do neutral, acidic or basic salt solutions respond to litmus test?
1. Neutral Salt- No change in the color of litmus.
Acidic Salt-Turns blue litmus to red.
Basic Salt- Turns red litmus to blue.
2. Neutral Salt- No change in the color of litmus.
Acidic Salt- Turns red litmus to blue.
Basic Salt- Turns blue litmus to red.
3. Neutral Salt- Turns blue litmus to red.
Acidic Salt- No change in the color of litmus.
Basic Salt- Turns red litmus to blue.
4. None of these.

Answer 1

Litmus test is a test used to differentiate between acidic ,basic and neutral conditions. Litmus test is done with the help of litmus paper which turns its colors as per the type of solution, whether it is acidic alkaline or basic.

Complete Step By Step Solution:
- Definition of Ph: It is a figure expressing the acidity or alkalinity of a solution on a logarithmic scale on which 7 is neutral, values lower than 7 implies acidic nature and if ph is more than 7 then the solution is alkaline.
Let us first look what is litmus test
- Purpose of Litmus Test: Litmus test is used to detect whether the solution is acidic, basic or neutral. Litmus Paper is used to detect this. When red litmus paper turns blue then the solution is basic. And when blue litmus paper is turned into red then the solution is acidic. For neutral solution color remains the same.
- Uses of Litmus Test:
The main use of litmus is to test whether a solution is acidic or basic.
Wet litmus paper can also be used to test for water-soluble gases that affect acidity or basicity; the gas dissolves in the water and the resulting solution colors the litmus paper. Ammonia gas turns red litmus blue, as ammonia gas is alkaline in nature.
So from the above discussion it is clear that correct answer is:
Neutral Salt- No change in the color of litmus. As it is neutral in nature.
Acidic Salt-Turns blue litmus to red. As acids turn blue litmus red.
Basic Salt- Turns red litmus to blue. As bases turn red litmus blue.

**So the correct option is 1st.

Note:**
If the pH of the solution is between 0 and 7 then the solution is acidic. If the pH of the solution is 7 then the solution is neutral. If the pH of the solution is between 7 and 14 then the solution is alkaline or basic in nature.
