Hydrogen chloride is soluble in water, so attempting to collect it over water would result in a significant amount of the gas being lost as it goes into an aqueous solution that will soon become dangerously acidic.

How is chlorine collected?

Chlorine gas is typically collected by passing air or oxygen over molten sodium chloride (table salt) in a process called electrolysis. The chlorine gas is then extracted from the mixture and collected in a separate containment vessel.


Why is ammonia gas not collected over water?

Ammonia 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.


Compare the densities of hydrogen oxygen and water?

Water is a compound and Hydrogen and Oxygen are elements. Elements are substances whose atoms all contain exactly the same number of protons. Water has a melting point over a hundred degrees above the boiling point of either Hydrogen or Oxygen. This is why water is mostly in its liquid form on earth's surface and Hydrogen and Oxygen are always found as gasses. Water is also one of the very few substances whose solid is less dense than its liquid. This is why ice floats.


What is hydrogen peroxide broken down into?

Hydrogen peroxide can break down into water (H2O) and oxygen (O2) when exposed to light or heat. This decomposition reaction occurs naturally over time, especially in the presence of certain catalysts like metals.


What does adding calcium chloride flakes do for your pool water?

Calcium chloride increases the hardness of water. Proper hardness is critical to balancing the water in a pool. Proper hardness is especially important in a plaster pool to prevent leaching of the plaster finish, which results in a rough surface. Calcium chloride can be purchased at home improvement stores at significant savings over pool supply outlets.

Why the hydrogen gas collected from the reaction of the metal with acid is called wet hydrogen gas?

Wet hydrogen is collected over a water surface.


Why the hydrogen gas collected from the reaction of the metal with acid is referred to as wet hydrogen gas?

It is called wet hydrogen gas because it is collected over water.


Can you collect hydrogen gas over water?

Yes, hydrogen gas can be collected over water by displacing the water in a container with the gas. Hydrogen is less dense than air so it will displace the water, allowing the gas to be collected in the container while the water is pushed out.


Which gas may be collected over water?

No, only those that do not dissolve in water, or they will dissolve in the water rather than bubble through it to be collected. Examples of gases that can be collected over water include:- Hydrogen, nitrogen, oxygen (only slightly soluble), methane, carbon monoxide. Examples of gases that can just be collected over water (quie soluble - so much will be dissolved in the water as well):- Nitrogen dioxide, carbon dioxide, chlorine Examples of gases that are too soluble to be collected over water:- hydrogen chloride, ammonia (which is the most soluble of all gases) Both of these gases are collected by displacement of air - hydrogen chloride by the gas jar being held as in a glass - with the base on the table - because it is heavier than air (chlorine and carbod dioxide can be collected like this too) and and ammonia by the gas jar being held upside down to trap the ammonia (as it is lighter than air).


Can distilled water be electrolysed?

Yes, distilled water can be electrolysed. Water always contains a few hydrated hydrogen ions and hydroxide ions from self ionization. There can also be some chloride ions because hydrogen chloride can distil over with water. However, the concentration of ions is extremely low so electrolysis is very slow.


How do you collect hydrogen chloride over water?

HCl reacts with water to form hydrochloric acid - eventually you would form "fuming" hydrochloric acid at concentrations over 35%. Collection over water is not a practical method of collecting the gas.


How can I use the collecting gas over water calculator to determine the amount of gas collected over water?

To use the collecting gas over water calculator to determine the amount of gas collected over water, you need to input the volume of gas collected and the temperature and pressure of the gas. The calculator will then calculate the amount of gas collected over water based on these inputs.


Why oxygen gas is collected over water?

Oxygen gas is collected over water because it is not very soluble in water, so it will not react with or get absorbed by the water. This allows for a pure sample of oxygen gas to be collected.


Why is ammonia not collected over water?

Because ammonia is quite soluble in water, so that not all of the gas produced could be collected over water.


Why hydrogen cannot be collected over air?

Hydrogen is highly soluble in air. You won't be able to collect it it over air. Hence other methods are preferred


How will you test the envolved gases in electrolysis in water?

You can test the evolved gases in electrolysis of water by collecting the gases separately in test tubes placed over the anode and cathode. The gas collected at the anode is likely oxygen, while the gas collected at the cathode is likely hydrogen. You can confirm their identities by performing simple tests such as the re-ignition test for oxygen and the "pop" test for hydrogen.


What temperature will water and sodium chloride separate?

At any temperature over 0 0C water is evaporated and sodium chloride remain as crystals.
