Red litmus become blue in basic solutions.
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.
Litmus paper is blue when dipped in an alkaline solution, and red when placed in an acidic solution. The colors begin to merge when you test pH neutral liquids.
It stays blue.
Blue litmus turns red.
blue litmus remains blue while red litmus changes to blue
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
When litmus paper is dipped in wood ash, it typically turns blue. This is because wood ash is alkaline (basic) in nature, which causes blue litmus paper to remain blue and red litmus paper to turn blue. The alkaline substances in wood ash, such as potassium carbonate, raise the pH of the solution.
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 litmus paper turns blue under alkaline conditions.
Blue litmus paper will turn red in the presence of an acidic solution, while red litmus paper will turn blue in the presence of an alkaline (basic) solution.
When a strip of litmus paper is dipped into an acidic solution, it turns red. This is because litmus paper changes color in response to the pH of the solution it comes into contact with. In acidic solutions, the paper turns red, indicating low pH.
