A solution changes the colour of turmeric indicator from yellow to red. The solution is
Open in App
Solution
The correct option is A Basic
Explanation for the correct answer:-
Option (A) Basic
- Turmeric is a natural indicator that helps us to identify whether a given solution is an acid, base, or neutral compound.
- This changes colour when dipped in a solution according to the pH of that particular solution.
- In an acidic medium the turmeric solution remains yellow, and in a basic medium, the turmeric solution changes colour to red.
- Thus here the colour changes to red which means the solution is basic.
- Hence it is the correct option.
Explanation for the incorrect answer:-
Option (B) Acidic
- Here the colour of the turmeric changes to red which means the solution is basic.
- But the option is given as red, so it can not be possible.
- Hence it is the incorrect option.
Option (C) Neutral
- In a neutral solution the turmeric does not change colour.
- It only changes colour if it's in an acidic or basic medium.
- Hence it is the incorrect option.
Option (D) Either neutral or acidic
- Here the colour of the turmeric changes to red which means the solution is basic.
- In a neutral solution it does not change colour and in an acidic medium, it changes to yellow.
- Hence it is the incorrect option.
Therefore, option (A) is the correct answer.
