What color does red cabbage indicator change to in alkali?
either a green, dark green or blue colour for i have done the test myself
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.
Is alkali soluble in water?
you can find out if a substance is an acid or alkali by adding universal indicator
What is the test for an alkali?
One common test for an alkali is using red litmus paper - it will turn blue in the presence of an alkaline substance. Another test is using universal indicator paper, which will show a color change to indicate the presence of an alkali.
What is universal indicator state the purpose for which this indicator is used?
Universal indicator is a mixture of dyes that changes color in response to different pH levels. It is used to determine the approximate pH of a solution by observing the color change of the indicator when added to the solution.
How do you test if an alkali is dangerous?
Put in some universal indicator and find the colour. Correspond this to bthe pH scale to find how dangerous it is.

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.
Is alkali soluble in water?

How can you tell if its an acid?
Add an alkali substance to it, such as chalk, if it is an acid it will "fizz" and release carbon dioxide. You could also test with Litmus Paper or Universal indicator.
Why is water used as the universal indicator?
Water is NOT Universal Indicator. Water is often referred to as a Universal Solvent as a large number of substances are soluble in it. Universal Indicator is a chemical agent that can be used to test the pH of a liquid.
What is the test for an alkali?
One common test for an alkali is using red litmus paper - it will turn blue in the presence of an alkaline substance. Another test is using universal indicator paper, which will show a color change to indicate the presence of an alkali.
How can you test for an alkaline or acid?
With a universal indicator or with litmus paper.
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.

Universal indicator is a mixture of dyes that changes color in response to different pH levels. It is used to determine the approximate pH of a solution by observing the color change of the indicator when added to the solution.
What are the disadvantages of universal indicator?
they are too expensive to get hold of
