A weak acid would typically be a shade of orange or red in universal indicator, indicating a pH of around 4-6.
The universal indicator turns red in acidic solutions.
Universal indicator will turn red or pink in dilute hydrochloric acid.
Citric acid is a weak acid, so it would turn a universal indicator to orange or red.
Universal indicator typically turns red in battery acid, indicating that the acid is highly acidic.
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.
The universal indicator turns red in acidic solutions.
Universal indicator will turn red or pink in dilute hydrochloric acid.

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.
A universal indicator changes to red when mixed with a strong acid.
red
When acid is added to universal indicator, the indicator will typically change to shades of red, orange, or yellow, depending on the strength of the acid.
Citric acid typically turns red when using a universal indicator, indicating that it is acidic.
Sulphuric Acid is colourless. When universal indicator (UI) is added, sulphuric acid remains colourless. The universal indicator turns 'RED'. Howver, because the UI is in solution with the sulphuric acid, the solution appears to be red.
Acetic acid, a weak acid, is typically a colorless liquid in universal indicator. When dissolved in water, acetic acid will appear yellow, indicating it is acidic with a pH around 3-4.
Universal indicator changes to red/orange when hydrochloric acid is added, indicating that the solution is acidic.
