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.
No. Ammonia is a base, and will turn red litmus blue without changing the colour of blue litmus.
Ammonia gas would turn universal indicator paper blue or purple depending on the concentration of ammonia present.
When orange filter paper is dipped into SO2 gas, it turns colorless or white due to the bleaching action of sulfur dioxide on the dye in the filter paper. This color change is a characteristic test for the presence of SO2 gas.
1. It has a pungent smell 2. direct the gas to a damp red litmus paper. If the litmus paper turns blue, it is ammonia gas
No, it shouldn't...AgNO3 has a neutral pH of 6, so the paper probably won't change colors.
When dipped in ammonia, pH paper will turn blue or blue-green. This color change indicates that the solution is basic or alkaline due to the presence of ammonia.
The red litmus paper dipped into household ammonia will turn blue. This is because ammonia is a base and reacts with the acidic red litmus paper, causing it to change color to blue.
orange
Universal indicator paper will turn blue or blue-green when dipped into ammonia solution, indicating that the solution is basic or alkaline.
It would turn Green
blue
yellow
The color become blue.
dark green
blue
blue
The blue litmus paper will not change color. Red litmus would turn blue in the presence of ammonia. Blue litmus paper will only change color in the presence of an acid, at which point it will turn red.
