A weak acid is a acid with a pH scale just below 7. The closer to seven the weaker an acid it is, a acid with a lower number is a stronger acid then an acid with a higher number. (no acids have a pH above 7)
Ascorbic acid and universal indicator together usually create a light green color.
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.
An indicator is a substance that changes color when exposed to an acid or base.
When ethanoic acid is added to universal indicator, it typically turns the solution a pink to red color, indicating that it is an acidic substance.
When acid is put on china rose indicator, the indicator will turn red in color. This color change indicates that the solution is acidic. China rose indicator contains anthocyanin pigments that change color based on the pH of the solution.
This indicator changes his color.
it depends on the indicator!

An acid base indicator is a chemical substance that has the ability to change color depending on the pH.

it turns yellow
Recreation of an indicator using an acid and a base involves mixing a colorless or faintly colored acid-base indicator with an acid to make the solution acidic (and change color) and then adding a base to neutralize the acid and return the indicator to its original color. This process demonstrates the reversible nature of acid-base indicators and how they can be used to visually indicate the presence of acids or bases in a solution.
The indicator turns pink when an excess of hydrochloric acid has been added in a titration.
No, ethanoic acid (acetic acid) is a weak acid and will turn universal indicator a different color depending on its pH level. It will likely turn universal indicator red or orange indicating acidity.
