Title: What is "fully protonated form"?
Post by: 3mpathogens on August 21, 2021, 01:15:36 PM

I'm just starting analytical chemistry and my textbook continually refers to acids and bases in their "fully protonated form". Does this mean that the compounds are being shown (structurally) with all hydrogen atoms still attached? What would it look like if they were shown in a partially protonated form, or in a non-protonated form?

I don't think it is just about structure (although yes, it would mean all hydrogens "attached"). In analytical chemistry equilibrium (be it dissociation, complexation, or anything else) is one of the most important things responsible for what we do and how, so the distinction between all acid (base) forms present in the solution is very important.
