Neutralisation as a proton-transfer reaction (1 Viewer)

[Jaserius]

How is neutralisation a proton transfer reaction?

Thankyou.

A proton is an H+

so say HCL + NaOH --> NaCl(aq) + H20(l)

But this is just

H+ Cl- Na+ + OH- --> NaCl (aq) + Water(l)

Bronsted-Lowry definition of an acid- proton donor (H+ donor)
base- proton acceptor (H+ acceptor)

does that help?

HCl + NH₃ → NH₄⁺ + Cl^-

The H⁺ is transferred from the HCl molecule to the ammonia molecule forming ammonium.

I don't see how neutralisation is a good example of a proton-transfer reaction, unless you use the one above which does not produce water and therefore probably wouldn't make a good example for acid-base reactions.

It's much clearly demonstrated in reactions between an acid or base and water.

Acid + water: HCl + H₂O → Cl^- + H₃O⁺

See how an H⁺ (a proton) was transferred from the HCl to H₂O? An acid is a proton donor.

Base + water: NH₃ + H₂O → NH₄⁺ + OH^-

Same thing. H⁺ is transferred from water to ammonia to make ammonium. A base is a proton acceptor.

Dreamerish apply to be a Benefactor. You deserve to be one.
nobody jeers at us anymore, I promise, it's cool

Lol, thanks.

You have no idea. I've applied twice already. I'm still on hold.

hmm admins are always busy did you say anyone recommended you? - that always helps lol

hey your light's on, could you help me with the threads in the POM and AE sub forums ? haha please.

Ah, no. Not recommended.

I answered your half-equation question. Anything else?

titration, in this same forum.
I recommend you

it's a dot point, so that's why we need to know it. It says identify that neutralisation is a proton transfer reaction. So we just need to know that it transfers a proton from the acid to the base and it becomes neutral.
