Which of the following describes the change observed when a few drops of lemon juice are added to a turmeric solution?
Options
Option A
The turmeric solution turns reddish-brown.
Option B
The turmeric solution turns blue.
Option C is correct
The turmeric solution remains yellow.
Option D
The turmeric solution turns green.

Lemon juice is an acidic substance. Turmeric acts as a natural indicator. Turmeric solution remains yellow when an acidic substance is added to it. It changes to reddish-brown only when a basic substance is added. Therefore, adding lemon juice to a turmeric solution will not change its yellow color.
