Litmus paper is an indicator that turns red in acidic solutions and blue in alkaline solutions.
Litmus paper is an indicator that changes color in acid and alkali solutions. In an acid solution, litmus paper turns red, while in an alkali solution, it turns blue.
the litmus test. blue means basic, red means acidic.
If you mix litmus solution with an alkali, the litmus solution will turn blue. Litmus is a pH indicator that turns red in acidic solutions and blue in alkaline solutions.
Using Standard Ph paper it is bright red. The paper should come with a color scale like so http://jchemed.chem.wisc.edu/jcesoft/cca/CCA3/STILLS/ENDO2/ENDO3/64JPG48/28.JPG
Bromothymol blue is an indicator that is pale blue in a basic solution and turns yellow in the presence of an acid.

Universal indicator turns shades of blue or purple in an alkali.
It turns red, alkali will turn it blue. A better alternative would be the univerasal indicator which also shows how strong/weak the acid/alkali is

Bromothymol blue is an indicator that is pale blue in a basic solution and turns yellow in the presence of an acid.
Universal indicator turns deep blue or violet when mixed with a strong alkali.
A red litmus paper turns blue in the presence of a base/alkali, while a blue litmus paper turns red in the presence of an acid.
The color does not change unless an indicator such as litmus or phenolphthalein is being used. If litmus the color change is blue to red If phenolphthalein the change is red to colorless
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.
Red/blue red turns to blue to detect alkali blue turns to red to detect acid
