What colour does blue litmus paper turn when dipped in alkaline?
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.

What color does pH paper turn when dipped in ammonia?
Unfortunately, it depends on the type of pH paper. If you mean standard litmus paper, it will be red (red litmus paper stays that way and blue litmus paper will turn red). Universal indicators change multiple colors depending on pH. If you have dilute concentrations of the same acid you will actually get different colors since pH indicates how much acid is dissociated, not how strong the acid is. Many universal pH indicators turn green colors at low pH.
