What colour does citric acid turn an universal indicator?
Citric acid is a weak acid, so it would turn a universal indicator to orange or red.
What colour is citric acid in universal indicator?
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.
What colour should weak acid be in a universal indicator?
A weak acid would typically be a shade of orange or red in universal indicator, indicating a pH of around 4-6.
What colour will universal indicator turn when mixed with a weak acid?
a bit of an weak orange colour, just look at any image of the chart
What colour is produced when universal indicator is added to acetic acid?
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.
What colour would you espect universal indicator to turn in a strong acid?
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
What colour should Acetic acid be in universal indicator?
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.
What colour will universal indicator turn when mixed with a weak alkali?
Universal indicator will turn purple or blue when mixed with a weak alkali.
What happens when carbon dioxide is bubbled into hydrogen carbonate indicator?
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.
How can you differentiate strong acid from a weak acid using an indicator?
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.
What colour is produced when universal indicator is added to lime juice?
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.
What is phenophthelein?
an indicator used for weak acid nd strong base
