pH 8 typically turns blue or purple with universal indicator, indicating that it is slightly alkaline or basic.
Bleach is a basic solution, so it will turn universal indicator to a purple color. This indicates a high pH level in the bleach solution.
Perfume typically does not have any effect on universal indicator as it is not a direct indicator of pH. Universal indicator changes color based on the pH of a solution, ranging from red (acidic) to purple (neutral) to blue (basic).
In weak alkali, universal indicator will typically turn green or blue. The specific color will depend on the pH of the solution - the higher the pH, the bluer the color.
In conditioner, universal indicator will likely turn a shade of purple or blue, indicating a slightly acidic pH level which is common in hair products.
When universal indicator is mixed with flour, it will likely turn a neutral color such as green or purple, depending on the pH of the flour. This indicates that the flour is close to pH 7, which is considered neutral.
Bleach is a basic solution, so it will turn universal indicator to a purple color. This indicates a high pH level in the bleach solution.

Sodium bicarbonate would turn blue or purple in universal indicator solution, indicating a basic pH level, around pH 9-10.
It turns green on neutralisation reaction.
The color of universal indicator in shampoo will vary depending on the pH of the shampoo. If the shampoo is acidic, the indicator will turn red or pink. If the shampoo is basic, the indicator will turn blue or purple. If the shampoo is neutral, the indicator will turn green.
Purple. Sodium Hydroxide is an Alkali/base. Bases and Alkalis have a pH greater than 7, and turn blue-purple in universal indicator.
The color is green for the universal indicator.
A weak alkali would typically turn blue or purple in Universal Indicator, indicating a pH around 8-10.
Universal indicator changes color in different pH ranges. In the case of ethanol, which is pH-neutral, universal indicator would likely show a green color.
