Purple
In a strong alkali, universal indicator typically turns dark blue or purple. This color change indicates a high pH level, usually around 12-14.
A universal indicator changes to red when mixed with a strong acid.
Universal indicator turns dark blue or purple in a strong alkaline solution.
Citric acid is generally colorless in universal indicator. It is a weak acid, so it does not exhibit a strong color change in the indicator solution.
Sodium hydroxide turns Universal Indicator solution dark purple, indicating it is a strong base with a high pH level.
Universal indicator would be dark blue or purple in a strong alkali.
Universal indicator turns deep blue or violet when mixed with a strong alkali.
In a strong alkali, universal indicator typically turns dark blue or purple. This color change indicates a high pH level, usually around 12-14.
red
Universal indicator changes colour in acids and alkalis. Its colour shows the strength of an acid or alkali. strong acid= redweak acid= orange / yellowneutral= greenweak alkali= turquoise / bluestrong alkali= deep blue / purple The strength of an acid or alkali is shown on the pH scale of numbers.

Universal indicator turns dark blue or purple in a strong alkaline solution.
The chemical property of lithium that will be shown by the universal indicator is its ability to be an alkali metal. When lithium reacts with water, it forms lithium hydroxide, which is a strong base. This reaction will cause the universal indicator to turn blue or purple, indicating a basic pH.
Citric acid is generally colorless in universal indicator. It is a weak acid, so it does not exhibit a strong color change in the indicator solution.
Sodium hydroxide turns Universal Indicator solution dark purple, indicating it is a strong base with a high pH level.
