Litmus paper only shows if a substance is acid or alkali.
It will turn red if its cid, or blue if its alkali.
It doesn't show how acidic or alkaline it is (ie, the pH).
This is what universal indicator shows.
You can use litmus paper or purple cabbage juice to test if a substance is acidic or not. Blue litmus paper turns red under acidic conditions. If you search 'litmus paper chart' online you can find some pretty good charts to find just how acid the substance is.
To use litmus paper effectively for testing acidity and alkalinity levels, first, obtain a strip of litmus paper. Next, dip the paper into the substance you want to test. The paper will change color based on the acidity or alkalinity of the substance. Compare the color change to the provided color chart to determine the pH level.
A litmus paper is a indicator that is used to test for acids or bases
Online science class does not mean you can just google for answers. Read your textbook!
litmus paper is genrally used to verify whether a substance is acid or base
Blue litmus paper would be used and if the chemical is an acid the litmus paper would turn red.
Blue litmus turned into red by acids.So you have to blue litmus.
Litmus paper
The reaction of a litmus paper is contained solely on the litmus paper. The liquid/solution is unchanged when introduced to the paper. It's not advised to drink the liquid/solution if it's inedible, but litmus paper won't affect it.
by using an indicator like litmus paper!!!
After studying the color of litmus at different 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.
