So I'm studying for my chem I final and I ran across a question that is asking about acidity:
Which Brønsted acid (HCl (aq) or H2S (aq)) is the stronger acid and why is it the stronger acid?
Answer:
HCl is the stronger acid because chlorine has a greater electronegativity than sulfur, which gives the attached hydrogen atom more proton character.
I'm not understanding the reference to proton character. I have searched the internet and found nothing that talks to this nor can I find anything in my notes or textbook.
Can any of you enlighten me on proton character in this context?
Appreciate it!
