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.
instead of drying ammonia,P4o10 reacts with it thereby disrupting the process.
Concentrated sulfuric acid is commonly used to dry ammonia gas by absorbing any moisture present. The acid traps water molecules, leaving behind dry ammonia gas for various industrial applications.
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 gas does not contain any hydroxide ions, which are needed to cause a color change in litmus paper. However, when ammonia is dissolved in water, it forms ammonium hydroxide which can turn red litmus paper blue due to the presence of hydroxide ions.
Dry ammonia gas does not have an immediate effect on litmus paper because it is not in solution. However, when ammonia gas dissolves in water, it forms ammonium hydroxide, which is a basic solution that turns red litmus paper blue due to its alkaline pH.

Dry Hydrogen and dry nitrogen gas in the Haber process
By drying ammonia, I guess you mean ammonia gas.. To dry ammonia gas you pass it through a drying tube of sorts filled with KOH or NaOH pellets. This method is for almost dry gas, if you are getting your ammonia gas from a ammonia/water solution you probably have to predry it with anhydrous sodium sulfate or some other sort of dessicant before you lead it through the KOH/NaOH pellet filled drying tube.

Litmus is a natural dye that changes color in response to the acidity or basicity of a substance. When dry ammonia gas comes into contact with litmus paper, it turns blue, indicating that ammonia is basic. In solution, ammonia gas dissolves in water to form ammonium hydroxide, which also turns litmus paper blue due to the presence of hydroxide ions.
Ammonia solution is a basic solution and turns red litmus paper blue because it reacts with the water in the solution to form ammonium hydroxide, which is alkaline. Dry ammonia gas has no effect on litmus paper because it does not contain water to form ammonium hydroxide, which is responsible for the color change of the litmus paper.
Dry red litmus paper will turn blue in the presence of household ammonia. Ammonia is a base, so it will cause the litmus paper to change color from red to blue, indicating the alkaline nature of the solution.
Anhydrous calcium chloride cannot be used to dry ammonia because it forms a complex with ammonia, resulting in a less effective drying process. This complexation reaction reduces the ability of calcium chloride to remove water vapor from ammonia. Instead, molecular sieves or desiccants like potassium hydroxide are preferred for drying ammonia.
Dry litmus paper does not change color when added to dry ammonia gas because ammonia gas is not acidic or basic enough to react with the litmus paper. Litmus paper changes color in the presence of acids (turns red) or bases (turns blue), but ammonia gas is a weak base and does not exhibit a strong enough reaction to cause a color change.
