Well if you place blue litmus paper in saliva and it turns red, then the saliva is acidic. If you put red litmus in the saliva and it turns blue, then the saliva is alkaline. However, if the red litmus doesn't change colour and the blue litmus doesn't change colour, the saliva would be neutral.

Substance that turns blue litmus pink?
well as we know if we want to test a substance to see if its a base then we use red litmus paper and for an acid we use blue litmus paper. So if we are using blue litmus paper that means we are obviously testing to see if we have an acid right? So if we see it turn pink then that means that are substance is an acid but it is not very strong and also has some of a base to it. If you want to see what i mean look up a PH scale. Hope this helped. :)
What does experimental group mean in science?
is the experiment that you are testing
What does 12 funt mean when writing a research paper?
they probably meant 12 font which is the size of the letters for your paper.
What does it mean to have practical hands on knowledge?
Not book knowledge. Knowledge acquired by experimenting or testing by yourself.
What does did your results support your hypothesis mean?
It means that the results are in line with what you thought would happen, They do not prove your idea was wrong. (It doesn't mean the idea was definitely right, but it's the basis for more testing.)
Does litmus paper mean filter paper?
no
When the litmus paper turns orange what does it mean?
it is acidic

Which litmus paper do you use to identify an acid and how does it react?
Online science class does not mean you can just google for answers. Read your textbook!
What does it mean when blue litmus paper turns red when put in a liquid?
which the solution will be acid
What turns red in the presence of acid ad blue in the presence of alkali?
You probably mean litmus paper. (see https://en.wikipedia.org/wiki/Litmus.)
How can you show that something is an acid or a base?
Its easy. You could try the Litmus paper test. Take an acidic and a basic solution in separate test tubes. Now take a litmus paper and dip it first in the acidic solution, if the litmus paper turns red, that mean the solution is acid. Now, dip it in the basic solution, if the litmus papaer turns blue that means the solution is basic.
What does the colour change of blue litmus paper to red mean?
The colour is red in acidic solutions.
What blue litmus paper mean?
it's a tester which turns red in contact with acids
Does litmus paper fade after being used?
There are a couple of different things this could mean. I'll try to address them all. Litmus paper is a strip of blotting paper soaked in a solution of an indicator called litmus. Litmus turns blue in the presense of basic solutions, and red in the presence of acidic solutions. If you use a strip of litmus paper to check on the acidity (or alkalinity) of a solution, it may change color. This color will probably slowly fade over time as the litmus reacts with acids or bases in the air, such as vinegar fumes or ammonia, until it reaches the sort of grayish state of neutral litmus. Exposing it to another acid or alkali should bring the color back. Also, if you immerse a strip of litmus paper in a solution, some of the litmus in the paper may leach out. This isn't likely to cause a dramatic fading, but it could be noticeable over time, especially if you keep using a single strip of litmus paper and rinsing it after each use.
What does litmus mean?
a litmus tells us if a substance is acidic or alkaline an acid will turn red litmus paper blue and an alkali will turn blue litmus paper red. if an unknown substance is tested with litmus and the colour did not change, then the substance is said to be neutral or it can be simply water. note that water is needed for acids to show its acidic properties........
What are litmus paper used for?
The litmus paper is used to evaluate the pH of a solution.
