Do acids turn universal indicator solution green?
Universal Indicators vary slightly, so always consult the colour chart provided by the manufacturer, but acids tend to give reds, oranges and yellows.
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.
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 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 an alkali comes out with a universal indicator?
Blue/Violet/Indigo . depending on the strength of the alkali. Water (neutral ) is green Acids ' Red/Orange/Yellow.

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.
When universal indicator solution is added to vinegar it turns what color?
It will turn a yellowish orange due to the acetic acid in vinegar. Carboxylic acids are weak by nature.
What happens to all acids when an indicator is added?
universal indicator goes from yellow to dark red when put in an acid. there are many other indicators that all go different colours
What is the name of the solution to test for acids or alkalis?
There are various ways to test for an acid and an alkali. For acidic solution: Litmus paper/ litmus solution --> red Phenolphthalein --> colorless Methyl orange --> pink Universal Indicator (changes color according to the strength of acid) --> red to yellow. For alkaline solutions: Litmus paper/ litmus solution --> blue Phenolphthalein --> pink Methyl orange --> yellow Universal Indicator --> blue green to purple
How are acids and bases tested?
universal indicator or litmus paper
What color change does each indicator show to represent acids bases and neutral?
There are far too many indicators to give them all. Litmus is blue in alkali, red in acids and an in-between colour often called claret when neutral. Universal indicator is red in strong acids, blue in strong alkalis and different colours in between depending on the brand.
