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.
Ammonia is a basic gas. It is not a neutral gas.
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)
The most common way is to place a damp red litmus paper near it. It turns blue if the gas is ammonia.Place a damp red litmus paper over the mouth of the test tube. Ammonia gas turns damp red litmus paper blue. Ammonia also has a pungent odour.Ammonia turns red litmus into blue.It also emmits a white gas with HCl.
Litmus paper tests the acidity or baseness of liquids.
Hydrogen chloride gas is not an acid, is not in solution and does not donate protons. So, no litmus paper color change.
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.
Ammonia is a basic gas. It is not a neutral 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

Ammonia is the only common alkaline gas so we usually test it with damp red litmus paper. If it goes blue that shows you have ammonia.
Ammonia is a useful gas. Normally it is a basic gas.
Hydrogen chloride gas is not an acid, is not in solution and does not donate protons. So, no litmus paper color change.
AS HCL DONATE ELECTRON IT HAS NO EFFECT ON DRY LITMUS PAPERType your answer here...
Dry ammonia is dried ammonia gas. The process of drying ammonia is very easy to pull through. You will just need to pass the ammonia gas through a tube filled with KOH or NaOH pallets.
