I think it is supposed to be PURPLE. Because of the following:
It turns red when placed in acidic solution
It turns blue when placed in alkaline solution
And purple when placed in neutral.
If litmus paper is added to washing up powder, it would typically turn blue, indicating that the washing up powder is alkaline (basic). Most washing up powders contain sodium carbonate or other alkaline substances, which raise the pH and cause the blue color change in blue litmus paper. If red litmus paper is used, it would remain red, confirming the basic nature of the solution.
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.
If the antacid is basic, litmus paper would turn blue. If the antacid is acidic, litmus paper would turn red.
Stomach acid is acidic, so litmus paper would turn red when exposed to it.
When a metal oxide is dissolved in water, it typically forms a basic solution. In this case, blue litmus paper will remain blue, indicating the basic nature of the solution. If the metal oxide were to produce an acidic solution, red litmus paper would turn blue, but this is less common for metal oxides.
Blue. This answer assumes that you are referring to litmus paper.
Lithmus will give a red color when added to acidified water or it will turn to red when neutral water is acidified.Remember:Litmus turnsBlue in BasicreD in aciD
Hydrochloric acid is an acidic solution, so when litmus powder is added to it, the litmus powder would most likely turn red. This is because litmus paper turns red in acidic solutions and blue in basic solutions.
Litmus paper is a sort of dark mauve colour in neutral substances like water. It was traditionally described as 'claret', though I never thought it looked like the claret I drank.
Because Vinegar is an acid, the litmus paper would turn 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.

Blue litmus paper turns red in an acidic solution.
If the antacid is basic, litmus paper would turn blue. If the antacid is acidic, litmus paper would turn red.
Depends on the litmus paper. Red litmus will not turn but blue litmus will turn redish pink.
