HCl + H2O (Hydrochloric acid plus Water)

- In this video we will look at the equation for HCl + H2O and write the products. When we add HCl to H2O the HCl will dissociate and break into H+ and Cl-. Since the H+ (often called a “proton”) and the Cl- are dissolved in water we can call them H+ (aq) and Cl- (aq). The aq stands for aqueous - something that is dissovlved in water.
When placed in water the H+ will combine with H2O to form H3O+, the hydronium ion. So another way to write H+ (aq) is as H3O+ .

O chem was a nightmare for me
Hii
I'm currently finishing year 11 chemistry, starting year 12 next week, and I have used you the whole time, you don't know how much help you are, its actually crazy. You help high school students and even tertiary students across the world, I hope you know that.
Have you got your A-levels now?
am i the only idiot who searched for the omori ost then ran into this and got interested?
Sunny would approve!
No 😭😭
welp
You are literally the best chem youtuber out there. keep on doin' your thing
Thanks for the kind words! --- Dr. B
nice pfp
@@naveensundar4765 thanks! you too

I thought it was mine comment. Same profile picture :D
VLW MANIN, ME SALVOU NA TAREFA QUE NEM VALE NOTA!!! S2
If HCL was used as a reactant in a formula equation (when writing NIEs), in order to write it as H30+ and Cl-, would I have to include the H20 in the reactant part of the formula equation? Thank you!
Very useful! Thankss
Excellent! Glad I could help with HCl + H2O. --- Dr. B
Thanks dr.
is it possible to mix completely H²O and HCI? Why?
Does this reaction occur when we drink water during a meal?
Would this be consider hydrolysis?
learning from INDIA ❤️🇮🇳❤️
This guy helped me during exam
Thank you teacher 🙏
Welcome!!
So if HCl was (aq) will the components be H3O + Cl or H+ + Cl +H2O
Either would be acceptable really. Technically I suppose H3O+ would be more descriptive. --- Dr. B
This is Exiilet teaching 🙏🙏
only real one here
Thanks aise hi video banate Rahe
Will the concentration increase if we add more acid to an aqueous solution of the same acid?
Please reply.
Yes
when we have HCl (aq) (meaning its already dissolved in water) then when we add the h20 (in the reactant side of equation) does it mean we're just adding more water to an acid thats already been dissolved in water
Yes, that is essentially what is happening. You're diluting the acid. --- Dr. B
@@wbreslyn thanks!
Can you tell me how we turn HCl( gas) into acid? Does hcl ( gas ) reacts with h2o chemically or physically to turn into ACID, or do I get it wrong? Please answer!!
It is all made up
Hello! 10th grade chem student here. I was wondering, what type of reaction is HCl + H2O -> H3O + Cl? I was told it was single replacement but I don’t know lol. But if a stupid question but I haven’t been able to find a good answer, thanks!
It's double displacement
Thank you
You are welcome!
Can we write the reaction as hcl+h20-> h30+ +cl-+h20
Most teachers would consider that correct.
See th-cam.com/video/Jm0kFK5IiGo/w-d-xo.html
What is going to happen to h30+ conc.....it will increase or decrease...same question about Oh-
If you put HCl in water it dissociates into H+ and Cl-. The H+ is really H3O+ .
See th-cam.com/video/Jm0kFK5IiGo/w-d-xo.html
Then it is H3O++Cl-right
That would be correct since the H+ would join with a H2O molecule to give H3O+. --- Dr. B
I thought the HCI donates a hydrogen ion to the water? can you explain?
The proton is the same thing as H+ . Hydrogen only has one valence electron so when it loses that it is just a proton.
So HCl is the molecule of hcl GAS, and h3o+ + cl- is the molecule of hcl ACID ? please answer . does hcl molecule change when it turn into acid ?
If you have HCl as a gas it is just HCl (g). It is not split apart. But when aqueous (dissolved in water) it will dissociate completely since HCl is a strong acid. So I'd agree that HCl(g) is the molecular form.
so we would say that its an Hydrolisis mr. Wayne?
what type of reaction is this? would you call it a dissociation reaction?
I'd say dissociation works, that is what is happening.
When hcl is made it is already dissociated into ions of h3o+ and cl- then why do we write hcl(aq)+h20(l)=h30+cl? because water hasn't done anything hcl was already dissociated before
Unless it is a gas being bubbled into water. But I see your point.
Ohhk..Thanks for answering 👍🏻
Is HCL + H2O --> H3O + CL correct ??
I'd say that when you add HCl to water you get either
H+ (aq) + Cl- (aq)
or
H3O+ (aq) + Cl- (aq).
I'd accept either an instructor.
---- Dr B
No
Hi there may I know what is the chemical equation of
“Hydrogen chloride gas dissolve in water forming hydrochloric acid”
Thank you for your help
So Hydrogen chloride would be a gas. I suppose you could say the products are HCl (aq). If you needed to show them as ions this video should help: th-cam.com/video/NQnHyaAlcHo/w-d-xo.html
2 liquids go to gether and become water
Is it also correct to write H+ + CL- rather than H30+ + CL-
Good question. Either way is correct but some instructors have a preference, so be sure to check.

Facts yo
Why acids dissociate when they are in water?
why doesnt cl become cl2 isnt it a diatomic element?
That's because Cl- is very different from Cl. The chloride ion (Cl-) is surrounded by water molecules and won't form Cl2. Also note they are both negative and wouldn't be able to get near each other without repelling.
Why does hcl break down in the first place and that too only in water
We call this reaction "dissociation", right?
Yes
Why does the HCl turn into H+ and CL-? why is the hydrogen positive all the sudden and the Cl negative? Thanks in advance, i'm in ninth grade and trying to understand some concepts right now
That's a bit of a long explanation. This video might help, it is similar.

What if the equation was written like this and I would have to fill in the blanks:
HCL(g) -->(water) ________(________)+________(________)
Hey won't the acid HCl be diluted when added to water?
And is HCl (g)+H20=HCl(aq)+OH? ?
plz reply fast
Yep, it will be diluted. There is some OH- in water naturally. But when you put HCl in water it will dissociate into H+ and Cl- which will be dissolved in the water (aqueous). --- Dr. B
So I will get HCL(aq) and what?
Is it hcl acid + water forms h3o+ and cl-
Or hcl gas + water forms h3o+ and cl-
Both would take place.
Thanks
You're' welcome!
Hcl gas behaves as acid in water only can you tell me why in short note
Because the H and Cl dissociate to give H+ and Cl-. H+ is the Arrhenius definition of an acid! --- Dr B
Note: See th-cam.com/video/NQnHyaAlcHo/w-d-xo.html for a fuller explanation.
What is acid and what is base in hi reaction
In this reaction the HCl is the acid and the water acts as a base. --- Dr. B
@@wbreslyn then why doesn't it form salt and water
@@wilder3183 That's because it is not a neutralization reaction (like NaOH + HCl). Here the HCl dissolves (you could say dissociates) in the water. No salt is formed because you don't have a metal involved. Salts (ionic compounds) are made of a metal and a nonmetal.

--- Dr. B
is HCl an electrolyte?
It is a strong acid so it is also a strong electrolyte.
Pov I stavin then I have HCl in my stomach then I drink water, I burp so I want to know that what did I burp?
You probably swallowed some air which made you burp. But if any fluid came up it would be acidic (and taste sour),
@@wbreslyn LMAO
Where does the Cl- go?
It is dissolved in the water as the chloride ion (Cl-). Same thing as dissolving NaCl in water, you get Na+ (aq) and Cl- (aq).
My question to all of you that if the hydrogen and chlorine fully dissociate and its also an irriversable reaction than how
Hydrochloric acid is formed ??????
I wouldn't say it is irreversible. The most concentrated HCl you can get is about 36% in an aqueous solution.
HCl is produced industrially as a byproduct of organic synthesis.
@@wbreslyn if that's so than why we say that's it fully dissociate in water if is not irriversable and also there is writen our ncrt book and all other books it has been written
