Action of sodium hydroxide on 0.1 bromothymol blue?

When sodium hydroxide reacts with 0.1 bromothymol blue, the solution turns blue initially due to the presence of bromothymol blue in its acidic form. As the sodium hydroxide neutralizes the acid, the solution changes color from blue to green and finally to yellow, indicating the increasing pH level. This color change is a result of the indicator's ability to change its molecular structure in response to changes in pH levels.


What happened to the color of bromothymol blue turn when HCI and NaOCI are added?

When HCl is added to bromothymol blue, the solution turns yellow due to the increased acidity. When NaOCl (sodium hypochlorite) is added, the color changes to green or blue, indicating the basic pH of the solution due to the formation of hypochlorous acid.
