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.
Do Acids turn universal indicator solution yellow or red?
Acids turn universal indicator solution red.
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.
What color does universal indicator turn in basic solutions?
The answer is Green.Proof at :http://www.sciencepages.co.uk/keystage3/year7/module5/m5quiz.phpI hope this helped.Goodbye.This is incorrect. It will be red, yellow, orange, deep red or red orange.
What makes universal indicator paper turn red?
Universal indicator paper turns red when the solution has a low pH, indicating that it is acidic. The red color is a result of the indicator's chemical reaction with hydrogen ions in the solution.

What is universal indicater?
Universal indicator changes colour in acids and alkalis. Its colour shows the strength of an acid or alkali. strong acid= redweak acid= orange / yellowneutral= greenweak alkali= turquoise / bluestrong alkali= deep blue / purple The strength of an acid or alkali is shown on the pH scale of numbers.
How do you test of acids an bases?
using an universal indicator, or you can use litmus paper or a pH meter.
What is the specific name of universal indicator?
A Universal indicator is a pH indicator composed of a solution of several compounds that exhibits several smooth colour changes over a pH value range from 1-14 to indicate the acidity or basicity of solutions. A universal indicator is typically composed of water, propan-1-ol, phenolphthalein sodium salt, sodium hydroxide, methyl red, bromothymol blue monosodium salt, and thymol blue monosodium salt.
What makes universal indicator paper turn red?
Universal indicator paper turns red when the solution has a low pH, indicating that it is acidic. The red color is a result of the indicator's chemical reaction with hydrogen ions in the solution.
