Yellow
Citric acid is a weak acid, so it would turn a universal indicator to orange or red.
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 weak acid would typically be a shade of orange or red in universal indicator, indicating a pH of around 4-6.
a bit of an weak orange colour, just look at any image of the chart
When universal indicator is added to acetic acid, it typically turns a shade of red, indicating that the solution is acidic. Acetic acid is a weak acid, so the color change may not be as intense as with stronger acids.
It would turn red in strong acid, orange/yellow in a weak acid, green in a neutral solution, blue in a weak base and purple in a strong base
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 will turn purple or blue when mixed with a weak alkali.
When carbon dioxide is bubbled into a hydrogen carbonate indicator, the indicator solution will turn yellow. This is due to the formation of carbonic acid, which is a weak acid. The carbon dioxide reacts with water in the indicator solution to form carbonic acid, causing the color change.
You can differentiate between a strong acid and a weak acid using an indicator by examining the pH change. A strong acid will cause a more significant decrease in pH and produce a more intense color change in the indicator compared to a weak acid, which will cause a less dramatic change in pH and produce a less intense color change.
an indicator used for weak acid nd strong base
When universal indicator is added to lime juice, it typically turns a reddish color, indicating that the lime juice is acidic. Lime juice is high in citric acid, which is why it produces this reaction with the indicator.
