A litmus paper is used to test the alkalinity or acidity of any substance. In the presence of an acid, a blue litmus paper will turn red and a red litmus paper turns blue to indicate the presence of alkaline.

∙ 10y agoRed litmus paper is used to test alkalinity (The strength of an alkali).
Dip the litmus paper in the solution, then remove it and place it down. Or for gases, put the Litmus paper at the top of the glass tube containing the gas you wish to test.
If it turns Blue the solution is alkaline. If it does not change colour at all the solution is acidic. If the colour changes to purple, it is neutral.
Blue litmus paper is used in a similar way but is for testing acidity. It turns red when it is exposed to acidic solutions.
The more apparent the change in colour is, the stronger the alkali or acid.

∙ 14y agoActual litmus paper is made using an indicator called litmus which is extracted from lichens. It's simply blotting paper soaked in a solution of litmus in water. However, you can make a substitute using the recipe below. This is what you need to make your "Litmus" paper: * Some grated fresh red cabbage * Water, enough to fill your jar * Paper towels, 2" strips * A wide-mouthed jar * Other fruits, flowers and vegetables How to do it: # Boil the cabbage in the water for about 10 minutes. # Let it cool down. # Strain it into a wide-mouthed jar. # Take your 2" strips of paper towels and soak it in the juice for a minute. # Let the strips of paper dry. # You now have your "Litmus" paper that you can use. # Now make paper in the same way with different substance such as fruits, flowers and vegetables. When we start testing, you will see that the color changes are different and because of what you see with the cabbage "litmus" paper, you'll be able to determine what color of your alternative "litmus" paper shows acid and what color shows you an alkali.

What litmus paper would you use to test for an acid and what is the color change?
Blue litmus paper would be used and if the chemical is an acid the litmus paper would turn red.
What kind of litmus paper do you use if you have an acid?
Blue litmus turned into red by acids.So you have to blue litmus.
Why do you test with litmus paper?
The main use of litmus is to test whether a solution is acidic or alkaline. Wet litmus paper can also be used to test water-soluble gases; the gas dissolves in the water and the resulting solution colors the litmus paper. For instance, ammonia gas, which is alkaline, colors the red litmus paper blue. Chemical reactions other than acid-base reaction can also cause a color-change to litmus paper. For instance, chlorine gas turns blue litmus paper white - the litmus paper is bleached.[5] This reaction is irreversible and therefore the litmus is not acting as an indicator in this situation
Does a base turn blue litmus paper blue?
yes a blue litmus paper turns red when put into an acid
How can you test for an acid and an alkali?
You would have to look at the nurk of the base and the whapple of the acid and i it is an xx and yy it would distinguish because then it dismanages it but otherwise if it is xy yx then it physicaly can't distinguish experimentally without tasting it.
What is a litmus paper and how to use it?
A litmus paper is a indicator that is used to test for acids or bases
What is the use of a litmus paper?
litmus paper is genrally used to verify whether a substance is acid or base
What color litmus paper is used to test acids?
Litmus paper.
What litmus paper would you use to test for an acid and what is the color change?
Blue litmus paper would be used and if the chemical is an acid the litmus paper would turn red.
What kind of litmus paper do you use if you have an acid?
Blue litmus turned into red by acids.So you have to blue litmus.
Why is it important to use blue and red litmus paper to determine pH?
Because if you only use red litmus paper and the solution you tested kept the paper red, you would think that the solution would also make the blue litmus paper turn red too. But what if the solution was neutral? Then the blue litmus paper would stayblue instead of turn red. Thats why you need to use both blue and red litmus paper.
When you test pH you use pH paper what is it called?
Litmus paper
What substance is used to determine the presence of an acid or base?
by using an indicator like litmus paper!!!
How can you use the litmus paper to develop a pH scale?
After studying the color of litmus at different pH.
What would a scientist use to test the pH of a substance?
Without an advanced technical method they use pH paper for quick answer. A more accurate method is to use a pH meter.
What cannot use for find pH of solution 1.ph paper 2.litmus paper?
pH papers are used to find pH of solutions, not litmus paper.
How do you separates dye from ink?
hey yes so my chemistry teacher said use litmus paper from GILLYYou use litmus paper.
