Answer:
The correct litmus test for an acid is:
blue litmus turns red
Explanation:
Litmus paper : It is a paper which contains 14 -15 dyes obtained from Lichens
It is also called <u>Acid-Base Indicator</u>
It is used to test whether the given solution is acidic or not.
If the solution is<u> acidic the litmus turns Red</u>
If the solution is<u> basic the litmus turns Blue</u>
<u>How to perform Litmus Test :</u>
Place the drop of given solution over the litmus paper.
If the Litmus paper is Blue initially and On adding a drop of given solution , it turn red then it indicate that the solution is acid with pH = 3 to 7
Red litmus paper does not change its color if the solution is acidic .
If the Litmus paper is Red initially and On adding a drop of given solution , it turn Blue then it indicate that the solution is alkaline . pH= 4 to 12
Blue litmus does not change its color in the presence of alkaline solution.
