If red litmus paper stays red when tested with a solution, it indicates that the solution is acidic or neutral, as red litmus is designed to remain red in acidic conditions (pH < 7). In contrast, if the solution were basic (pH > 7), the red litmus would turn blue. Therefore, a red litmus that stays red confirms the absence of basicity in the solution being tested.
In Acid the red litmus stays red but in a base the litmus changes to blu
blue litmus paper turns to red when its in contact with acid
Red litmus paper stays red in the presence of an acid and turns blue in the presence of a base. Blue litmus paper stays blue in the presence of a base and turns red in the presence of an acid.
After the complete neutralization the litmus color remain unchanged - purple.
It stays red.
A Blue litmus paper turns red in acid and stays blue in alkalin A red litmus paper turns blue in alkaline and stays red in acid
Litmus paper will turn red in the presence of HCl, indicating acidity. However, it will not show any significant color change when added to methyl benzene, as it is a nonpolar solvent and does not react with litmus paper to cause a color change.
Depending on what color of paper you are using it varies. Blue litmus paper turns red under acidic conditions and stays blue for basic conditions while red litmus paper turns blue under basic conditions and stays red under acidic conditions.
If you add red litmus paper and it remains red, then you add blue litmus paper and it remains blue, then the the solution is neutral. Kamal
in neutral conditions there is no change in colour of litmus....
this is very easy to understand if u place red litmus paper in a acid it turns red/pink. if u place red litmus paper in a base it turns blue. blue litmus paper in a acid turns pink/red. blue litmus paper in a base stays blue.
You use the blue litmus to to test an acid other wise no result of testing an acid
