Best Answer

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.

Dry ammonia ga s has no action on litmus paper but a solution of ammonia in water turns red litmus to blue. why?

because when ammonia gas react with water it forms ammonia hydroxide which is a base so that it turns red litmus paper into blue


Why do Solution of ammonia turns red litmus paper blue while dry ammonia gas has no action on litmus paper?

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.


Are Ammonia acids based neutral?

Ammonia is a basic gas. It is not a neutral gas.


Why doesn't dry litmus paper change color when added to dry ammonia 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)


What test can be used to confirm the presence of ammonia 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


How do you test for ammonia gas?

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.


Why does dry HCl gas not change the colour of the dry litmus paper?

Litmus paper tests the acidity or baseness of liquids.


How do you do a lab experiment to prove you have 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.


Is ammonia a acid or base?

Ammonia is a useful gas. Normally it is a basic gas.


Why does dry HCl gas does not change the colour of the dry litmus paper?

Hydrogen chloride gas is not an acid, is not in solution and does not donate protons. So, no litmus paper color change.


Why a dry blue litmus paper is not affected by hydrogen chloride gas?

AS HCL DONATE ELECTRON IT HAS NO EFFECT ON DRY LITMUS PAPERType your answer here...


What is dry ammonia?

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.
