I think it is supposed to be PURPLE. Because of the following:It turns red when placed in acidic solutionIt turns blue when placed in alkaline solutionAnd purple when placed in neutral.
Aspirin is acidic, so it would turn red.
Because if you only use red litmus paper and the solution you tested kept the paper red, you would think that the solution would also make the blue litmus paper turn red too. But what if the solution was neutral? Then the blue litmus paper would stayblue instead of turn red. Thats why you need to use both blue and red litmus paper.
Yes, sea water would change color with red litmus paper because sea water is basic. Under basic, or alkaline, conditions, red litmus paper turns blue. Being between the pH range of 7.5 and 8.4 (between 7 and 14 marks basic conditions), sea water is basic and, therefore, the red litmus paper will change color.
Dark Vilolet
Depends on the litmus paper. Red litmus will not turn but blue litmus will turn redish pink.
Because Vinegar is an acid, the litmus paper would turn red
red
Well if you place blue litmus paper in saliva and it turns red, then the saliva is acidic. If you put red litmus in the saliva and it turns blue, then the saliva is alkaline. However, if the red litmus doesn't change colour and the blue litmus doesn't change colour, the saliva would be neutral.
Well if you place blue litmus paper in saliva and it turns red, then the saliva is acidic. If you put red litmus in the saliva and it turns blue, then the saliva is alkaline. However, if the red litmus doesn't change colour and the blue litmus doesn't change colour, the saliva would be neutral.
Blue. Litmus paper turns blue under alkali conditions (pH over 7).
blue
blue litmus paper turns to red when its in contact with acid

Blue. This answer assumes that you are referring to litmus paper.
Well if you place blue litmus paper in saliva and it turns red, then the saliva is acidic. If you put red litmus in the saliva and it turns blue, then the saliva is alkaline. However, if the red litmus doesn't change colour and the blue litmus doesn't change colour, the saliva would be neutral.
