Question

If the pH indicator bromothymol blue was added to the nitric acid solution, it's colour would be?

Answer 1

Yellow

Step-by-step explanation:

Thymol blue has a brownish-green or reddish-brown color and is a good pH indicator. It changes from red to yellow at a pH 1.2–2.8 ( acidic) and then from yellow to blue at a pH of 8.0–9.6( alkaline).

Nitric acid is a strong acid which means the pH indicator will change to yellow.
