Is it true or false that strong acids turn universal indicator paper purple?
False. Universal indicator paper changes color based on the pH of a substance. Strong acids turn universal indicator paper red, orange, or yellow depending on the strength of the acid. Purple is not a color associated with strong acids on universal indicator paper.
Will strong acids turns universal indicator paper red?
Yes, strong acids will turn universal indicator paper red due to the high concentration of hydrogen ions present in the solution. Universal indicator paper changes color in response to the pH of the solution it is exposed to.
Will strong acids turn universal indicator paper purple?
The pH scale ranges from 0-14. Universal indicator makes very acidic substances (with a pH of around 0) appear dark red, neutral ones green and very alkaline ones dark blue.
What effect does hydrochloric acid have on universal indicator paper?
Hydrochloric acid will typically turn universal indicator paper red, indicating a low pH or acidity. Universal indicator paper changes color based on the pH of the solution it comes into contact with, with red indicating a strong acid.

What colour does universal indicator turn if you add vinegar?
Because oven cleaner contains Sodium Hydroxide (Na OH), a 'strong' alkali/base, to dissolve the grease, it would change Universal Indicator a deep blue/purple colour.
When water and universal indicator are added to magnesium oxide what colour does the solution go?
Copper oxide will turn blue or purple when Universal Indicator is put on it.If you found this helpful, please rate me :)
If universal indicator was added to the water after the reaction with caesium what colour would it be?
The universal indicator in water after the reaction with cesium would likely turn purple. Universal indicator changes color to purple in the presence of strong bases like cesium hydroxide, which would be formed as a result of the reaction with cesium and water.
Why would it be difficult to test a cup of coffee with universal indicator?
Because Coffee is a dark colour and if your testing it with universal indicator paper the paper might stain from the strong coffee colour and not be entirely accurate. I have never tried this personally its just as assumption.
