Red cabbage juice turns purple when sprayed with bleach.
It is a chemical change. The bleach reacts with the pigments in the hair, causing a chemical reaction that breaks down the natural color and can result in a yellowish tint.
Bleach typically turns a greenish-yellow color when tested with universal indicator due to its high pH level. This indicates that bleach is a strong base.
When paper turns yellow, it is typically a sign of oxidation caused by exposure to air and light. This deterioration is often accelerated by acids present in the paper itself or in the environment.
This represents a chemical change, as the formation of a cloudy and yellow solution suggests the formation of a new substance with different properties from the original solutions.

Bromothymol blue is a chemical indicator for weak acids and bases. The chemical is also used for observing photosynthetic activities or respiratory indicators (turns green then yellow as CO2 is added). Since dissolved O2 does not affect pH, the solution remains the same color it was when it was added (yellow for acidic, green for neutral, blue for alkaline).
