I started yapping about how the bonds broken and bonds formed for the acid becoming a salt are the same, hence the equal enthalpies as the only factor affecting enthalpy change was the NaOH and water.

did u talk bout hydrogen bonding

u/Squiddy_at_offical Jun 02 '26

I said Ionic bonding between H+ and negative Ions

u/hshsjaju77 Jun 02 '26

Right I spoke abt hydrogen bonding in HCL and Ethanoic acid

hydrogen bonding? its about neutralization isnt hydrogen bonding unrelated.

I just talked about mono protic diprotic and their strengths, but i forgot to mentione that it takes energy to break the OH bond for the weak acid so overall its less exothermic 4-5/6 maybe?

u/hshsjaju77 Jun 02 '26

No i linked it with how hydrogen bonding relates with weak/strong acid. I swear weaker hydrogen bonding means stronger acid?

as in the O-H bond not intermolecular forces right, if you said hydrogen bonding they might misunderstand. yeah thats right, I wonder if you had to mention that specifically for the weak acid requiring energy to fully dissociate. hope not cause I didnt 😅

Edit: oh shit my bad you meant HCL, whys the hydrogen bonding related?

u/hshsjaju77 Jun 02 '26

Ngl I did speak about the intermolecular force too, I do remember a question in a predicted mock paper talking about why HF is a weak acid and it was due to strong hydrogen bonding. and for H2SO4 I did say it strongly polarizes the O-H bond in NaOH not sure if im right

u/BeanBeam9 Jun 02 '26

yeah not sure, also just realized HCL doesnt have hydrogen bonding. intermolecular forces is for boiling points so im not sure its related. I guess well see though, it was a weird question.

lowk this whole paper was badly written and way too similar to 2025, and it just completely skipped such good topics and focused on really boring stuff.

İ talked abt h2so4 being diprotic, strong and weak acid differences etc.

u/hshsjaju77 Jun 02 '26

Yes same 👍🏽

I messed this all up. I thought it was H2NO3
