What is one limitation of universal indicator paper?
One limitation of universal indicator paper is that it may not provide a precise numerical pH value but rather a color change indicating a range of pH levels.
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 is an advantage of using a universal indicator to test the pH compared to using litmus paper?
A universal indicator covers a broader pH range compared to litmus paper, which only gives a rough indication of acidity. Universal indicators provide a more accurate and detailed measurement of pH levels.
Does a strong base turn a universal indicator paper purple?
Yes, a strong base will turn universal indicator paper purple. Universal indicator paper changes color based on the pH of the solution it is exposed to, and a strong base will cause it to turn purple, indicating a high pH.
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.
How you can conclude the pH value of a fabric?
we can conclude by using a ph paper or universal indicator.
What paper do you use to test for pH?
Litmus paper will determine acid or base. Universal indicator paper (pH paper) will give an answer to the nearest whole number.
What is one limitation of universal indicator paper?
One limitation of universal indicator paper is that it may not provide a precise numerical pH value but rather a color change indicating a range of pH levels.
How do you know why the universal indicator will be a certain colour?
Depending on the pH solutions have different colors with a pH paper.
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.

Yes, a strong base will turn universal indicator paper purple. Universal indicator paper changes color based on the pH of the solution it is exposed to, and a strong base will cause it to turn purple, indicating a high pH.
What is the pH value of toilet cleaing acid?
Just test it with universal litmus paper or universal indicator(liquid)
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.
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.
Measure the pH of 5 foods in the kitchen using the universal indicator paper and display the foods and their pH?
pH is so stupidd pH is so stupidd
How could you test for an acid or alkali?
To test for an acid, you can use pH paper or a pH meter to measure the pH level of a solution. Acids will typically have a pH below 7. To test for an alkali, you can use universal indicator paper which will change color depending on the pH of the solution. Alkalis typically have a pH above 7.
