ammonia is prepared by adding any ammonium salt to an alkali. a vivid mixture of slaked lime and calcium chloride are placed in a round bottomed hard glass flask. the glass is inserted in a retort stand with its mouth facing downwards with a delivery tube inserted from the glass to a drying glass containing quicklime or calcium oxide. a gas jar is inverted above the drying glass...

How is ammonia gas collected in the laboratory preparation of ammonia gas?
Ammonia gas is collected by upward displacement of air in the laboratory preparation. This involves passing the gas over water and collecting it by downward displacement because ammonia is lighter than air. The gas is then bubbled through water to dissolve any remaining gas before use.
What is dry ammonia?
Dry ammonia refers to anhydrous ammonia, which is a colorless gas with a strong pungent odor. It is commonly used in fertilizers, refrigeration systems, and as a cleaning agent. Handling anhydrous ammonia requires proper safety precautions due to its toxic and corrosive nature.
Why is dry ammonia gas neutral to litmus?
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.
What substance used for drying ammonia?
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.
What is the action of litmus on dry ammonia and solution of ammonia gas?
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.

What is the substance used to dry ammonia?
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.

Dry ammonia has no at litmus paper but your solution of ammonia in water turns blue why?
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.
Why doesn't dry litmus paper change color when added to dry ammonia gas?
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.
Why ammonia gas cannot be dried by using conc.H2SO4 AND P2O5?
Ammonia gas cannot be dried using concentrated H2SO4 and P2O5 because ammonia gas reacts with both chemicals. Ammonia reacts exothermically with concentrated H2SO4 to form ammonium sulfate and water. Similarly, ammonia reacts with P2O5 to form ammonium phosphate and water. These reactions do not effectively dry the ammonia gas as the water byproducts are produced.
How do I draw a particle diagram to represent the reaction used in the Haber process?
In the Haber process, nitrogen gas and hydrogen gas react to form ammonia gas. You can draw a particle diagram by representing nitrogen molecules (N2) as pairs of N atoms, hydrogen molecules (H2) as pairs of H atoms, and ammonia molecules (NH3) as a combination of N and H atoms. Show the collisions between nitrogen and hydrogen molecules and the formation of ammonia molecules.
