Using Standard Ph paper it is bright red.
The paper should come with a color scale like so

∙ 11y agoIf you add it to acid, it turns red, if you add it to alkali it turns blue, a stronger acid/alkali gives a stronger colour.

When you put an alkali and Universal Indicator in a test tube what colour does it go?
When an alkali is added to a test tube containing Universal Indicator, it typically turns the indicator solution a dark green or blue color. This is because Universal Indicator is a mixture of different pH indicators that show a range of colors from red (acidic) to green (neutral) to blue or purple (alkaline). The specific color change observed may vary depending on the concentration and type of alkali used.
What colour is produced when universal indicator is added to lime juice?
Assuming it to be mostly a weak acid, the color would be orange/yellow
How are indicators used to detect acids and alkalis?
Indicators (for example LITMUS PAPER) can detect whether a certain liquid is an acid or an alkali. Litmus Paper turns red when dipped in an acid, blue in an alkali Universal Indicators have show how strong or weak and acid or alkali is.
Color of sodium carbonate in universal indicator?
rouge
What is the colour of ammonia on a universal indicator?
pH of ammonia is around 11-12. Hence when you put it in a universal indicator, you get purple color.
What color did universal indicator if it is added to weak alkali?
blue
What color would universal indicator in strong alkali?
red

What color is the color of universal indicator?
they have so many colours because they show if it is an acid or an alkali
When a drop of universal indicator is added to water what is the colour change?
Pure water is neutral so the color will be green.
What color is the universal indicator in an alkali?
Many soluble dyes change their color with changes in pH (a measure of the concentration of acid in a solution). Such dyes may be used to indicate when the acid (base) in a solution has been neutralized by addition of an equal amount of base (acid). Each indicator dye has a particular range of pH for which it is useful. pH test strips and papers often incorporate two or more dyes to extend the range of pH over which they can be used. The best indicator dyes are strongly colored (so that only small amounts are needed), undergo an easily seen change with pH (either from one color to another, or from clear to colored), are nontoxic, and are chemically stable.
What color does universal indicator turn in deionized water?
since water is pretty neutral, the water does not change color but the universal indicator does. The universal indicator changes color as per the quantity of deionized water... But it changes to straw color or pale yellow in 50mL of deionized water.
What colour is produced when universal indicator is added to lime juice?
Assuming it to be mostly a weak acid, the color would be orange/yellow
What does universal indicator test for?
A universal indicator changes color in response to the pH of a liquid. Do determine the pH of the liquid, you need to refer to a color chart that tells you which color indicates which pH.
