Why protons dissociate

  1. Sep 8, 2014 #1
    I wondered if anyone could help me with a question. Do acids such as HCl donate protons because the conjugate acid is more electronegative? Such as the O in H2O is more EN than Cl, and thats why the H+ dissociates?

    It is not about just electronegativity - what is more electronegative, oxygen in SO42- or oxygen in H2O?

    I'd have to say So4^2- because it carries a negative charge, so it will attract protons...?

    What about HSO4- then?

    Thanks for that I'll watch it.

    That's actually really helpful. I see it's as I suspected more to do with the lewis bases ability to donate electrons. Like the protons are pulled from the acid.
