उत्तर
A solution turns the colour of turmeric to reddish brown. If the same solution is poured on universal indictor, its colour would change to Blue.
Explanation:
Turmeric is a natural indication that can help us determine if a given solution is acidic, basic, or neutral. If the pH is between 7.5 and 9.5, the turmeric paper turns reddish brown. As a result, the solution is straightforward. As a result, the Universal pH indicator will display the colour Blue or a little darker blue. Violet will not be present because violet is only seen in strongly alkaline bases.
