Unlike hydrated ammonia, there is nowhere for the extra proton to go and form hydronium, so there can be no change to a pH because there simply isn't one. Thus, the ammonia appears neutral.
Litmus paper detects alkaline conditions (presence of OH- ion). When dry, ammonia has no hydroxide ions. It needs to be mixed with water, where, in equilibrium, NH4+ and OH- ions are formed. If you wet the litmus paper, the dry NH3 gas will register as basic.
because dry ammonia does not contain water and it doesn't present H+ ions
nothing
litmus color changes into blue.
Saltwater is a neutral one. So you can use a red litmus paper.

because when ammonia gas react with water it forms ammonia hydroxide which is a base so that it turns red litmus paper into blue
Ammonia solution consists of ammonium hydroxide and water, the ammonium hydroxide is basic (due to the hydroxyl functional group). Dry ammonia doesn't have this functional group.
Saltwater is a neutral one. So you can use a red litmus paper.
no if ammonia is dry state den it is neither acidic nor basic but actually it is basic because it turns red litmus blue
Because to exchange protons (from Litmus to ammonia) some water molecules are needed for transfer: LitH+(red) + H2O + NH3 --> [ Lit + H3O+ + NH3 ] --> Lit(blue) + H2O + NH4+(aq)
Ammonia is a base, and will turn red litmus blue.
No. Ammonia is a base, and will turn red litmus blue without changing the colour of blue litmus.
The color of blue litmus in ammonia will remain to be blue . However the color of red litmus will change into blue. This is because of the basic nature of ammonia.
