ReneAmmonia gas reacts with water to form ammonium hydroxide, a basic solution. This reaction reduces the amount of ammonia gas collected and may lead to inaccuracies in the experimental results. To prevent this, ammonia gas is typically collected using an alternative method such as downward displacement of air or through a gas syringe.

Why ammonia gas is collected in an inverted gas jar?
Ammonia gas is collected in an inverted gas jar to prevent it from escaping into the surrounding atmosphere. Since ammonia is lighter than air, collecting it in an inverted jar ensures that it is trapped in the jar due to its lower density. This setup allows for safe and efficient collection of the gas for various laboratory purposes.
Is ammonia a solid liquid or gas at 20 degrees Celsius?
Ammonia (NH3) is a (very 'water' soluble) gas
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.
Why is water (H2O) a liquid at room temperature, whereas ammonia (NH3) is a gas at room temperature?
Water and ammonia have different intermolecular forces. Water molecules are held together by hydrogen bonding, which is stronger than the dispersion forces that hold ammonia molecules together. This difference in intermolecular forces results in water being a liquid at room temperature while ammonia is a gas.
What salts and sodium hydroxide produce ammonia gas?
Ammonium chloride (NH4Cl) and ammonium sulfate ((NH4)2SO4) can produce ammonia gas when reacted with sodium hydroxide (NaOH) through a chemical reaction, known as the Hofmann elimination reaction. This reaction forms ammonia gas (NH3) and water (H2O) in the process.
