Well, there are the three main ones which are neutral, acids, alkali
Hope this helped :)
Indicators used in precipitation titrations are typically complexometric indicators that form colored complexes with the analyte ions. These indicators change color when the endpoint of the titration is reached, signaling the completion of the precipitation reaction. Common complexometric indicators include EDTA, Eriochrome Black T, and Calconcarboxylic acid.
If a substance is an acid, it would turn red on a pH indicator
Sodium chloride is a neutral substance and will not exhibit a specific color in a universal indicator. Universal indicators change color based on the pH of a solution, not the presence of specific compounds like sodium chloride.
Universal indicator would be dark blue or purple in a strong alkali.
Universal indicator would likely turn red in ethanol, indicating that it is acidic.
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.
There is multiple, the most common would probably be Litmus Paper and Universal Indicator. The properties they have (the relavent ones) is that they turn a certain color when mixed with an acid or base.
Soda lime should register a pH above 7 when tested with a universal indicator. Soda lime is a mixture of chemicals including calcium hydroxide, which is a strong base. Universal indicators change color in the presence of different pH levels, with colors shifting towards blue for bases.
Universal indicator would turn blue or purple in soil containing alkaline.
The Universal Indicator would go green which is pH 7.
Citric acid is a weak acid, so it would turn a universal indicator to orange or red.
red
