Will strong acids turns universal indicator paper red?
yes strong acids will turn ph paper red
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 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.
What happens to the indicator when a base is added?
There are a huge range of indicators that can be used in chemistry, but I presume you'll be using the basic 'universal indicator' here. A base will turn this indicator (depending on its strength) light/dark blue, or purple if it is quite strong. Or do you mean in terms of chemical reaction?
What is universal pH paper?
Universal pH paper is a type of paper used to find the pH level of a solution and is an indicator.
Would strong acids turn universal indicator paper purple?
nope
What colour would ammonia gas turn universal indicator paper?
Purple:)
Will strong acids turns universal indicator paper red?
yes strong acids will turn ph paper red
What color does the indicator paper turn if the substance is a strong acid?
If you are testing with Universal Indicator or the Litmus Test it will turn red.

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 :)

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.

What is universal pH paper?
Universal pH paper is a type of paper used to find the pH level of a solution and is an indicator.
Why was universal indicator paper used to test the pH rather than placing universal indicator solution into the mixture?
Use of paper avoid the contamination of the sample.
How do you test for alkaline?
You could test the pH of the substance with UI (universal indicator) paper, or some other indicator. If the pH is <7 or the paper is red/orange/yellow, then its acidic. If the pH is >7 or the paper is blue/purple, then its alkaline. In-between is neutral (green).
