Blue litmus paper stays blue in a neutral solution. It turns red only when in an acidic solution. Similarly, red litmus paper would stay red in a neutral solution and turn blue in an alkaline solution.
Added:
acidic: pH below 5.5 it turns (stays) red
alkaline: pH above 8.0 it turns (stays) blue
neutral, in between 5.5 and 8.0: its color is purple,
between 'red and blue' or 'blue and red'
A much better indicator paper is universal indicator paper. It is yellow and can tell you the exact pH of the solution it is dipped in, going yellow to red in acidic conditions, blue to purple in alkaline conditions and green in neutral conditions. The exact colour depends on the pH.
Red, because litmus paper remains blue in alkaline solutions and turns red in acidic solutions.
The solution is alkaline, because litmus paper remains blue in alkaline solutions and turns red in acidic solutions.
nope actually, it stays blue and when u dip it in with red litmus paper it went blue, i did experiment so i kno << it would then be: alkali
Yellow litmus paper turns blue in alkaline substances.
Depends on the litmus paper. Red litmus will not turn but blue litmus will turn redish pink.
Red, because litmus paper remains blue in alkaline solutions and turns red in acidic solutions.
As soap is alkaline in nature, it turns red litmus paper blue
The solution is alkaline, because litmus paper remains blue in alkaline solutions and turns red in acidic solutions.
It stays blue.

Yellow litmus paper turns blue in alkaline substances.
blue litmus remains blue while red litmus changes to blue
Red litmus become blue in basic solutions.

Blue litmus turns red.
