Reaction of NH3 (g) + HCl (g) Can two gases make a solid? 🌪

Показать описание

If we take NH3 gas (a colorless gas) and mix it with HCl gas (another colorless gas) a reaction producing solid NH4Cl will take place. Where the NH3 and HCl gas come in contact with each other a white cloud forms. This white cloud is made up of very small solid crystals of solid NH4Cl (Ammonium chloride).

The chemical reaction can be written as:
NH3 (g) + HCl (gas) = NH4Cl (s)

As a word equation it would be written:
Ammonia gas plus Hydrogen chloride gas yields solid Ammonium chloride:

The particles of NH4Cl that form a so small that they look like smoke and take a long time to settle. After some time we could collect the Ammonium chloride crystals. If we were to heat the crystals up we could cause the NH4Cl to decompose back into NH3 (g) + HCl (g).

In answer to our question, two gases can react to form a solid. In this case NH3 (g) + HCl (g) produces the NH4Cl (s).

That was so cool to visually see that two gases in such a simple experiment to that. DVD:)

Yeah NH4Cl, a crystalline salt..we did this in our lab, also the dust was taking longer to settle in the test tube. When I got the HCl close to the NH3 it stated to react too soon and smoke started coming out of the HCl beaker. Ngl it was fun to watch...

Fun fact:

You can actually do a really cool experiment with this. Set a long glass tube down on a flat surface, and put a cotton ball soaked with ammonia at one end, and another cotton ball soaked with HCL at the other end at the same time as you place the ammonia one. You will slowly see a white line appear some distance between the two cotton balls. But the line won’t be directly in the middle of the tube like you might expect. The reason for this is that the gasses diffuse through the length of the tube at different rates. The place where they meet is where the vapor fronts of both gasses meet. You can actually measure the position of this white front, and use it to determine the relative rate of diffusion of ammonia gas relative to HCL gas.

Kinda a fun little demo you can use to experimentally prove the equation used to predict the rate of diffusion of ideal gasses

The chemistry is incredible, it hurts that they mostly serve the development of weapons.

Reverse sublimation. They just taught me that in college and got to see it personally, but the teacher didn’t tell us what would happen at the moment so it was a pretty cool class

The chemistry term for gas to solid, skipping the liquid phase, is deposition. Is that correct?

Could you do a video about endothermic and exothermic reactions or enthalpy?

This is what gives the taste to salty licorice. In this application its known under the name Salmiak and have a salty and very stingy taste. It burns on the tounge. Very popular in Finland, Sweden and also Denmark.

ayyy I remember this, in high school they use this to show Graham’s Law, both gas entered via each side of a horizontal placed tube and the crystal formed at….. maybe two-third of the tube?

The HCl donates a proton to the NH3, making Cl- and NH4+. The NH4+ and Cl- are then attracted to each other, forming NH4Cl.

Hlo, Sir, I have a question but that is not related to this toppic. sir i want to know what is the hybridization of O atom in Cl2O is it SP3 as normal rules says it. or it is SP2 according to back bonding of oxygen lone pairs to clorine vacant d orbital.watin for your amazing answer.

This reaction is constantly happening in our laboratory. We have all surfaces with a white coating

I guess if we mix them, We get Aqua Regia which can disolve any metal in it

NH3 is a smooth gas. It can react easily with HCI
