Acid dissociation

[Chris Dis3L]

Is it possible for 100% of an acid to dissociate with absolutely no atoms left un-ionized? If a strong acid can achieve complete dissociation, where is the cutoff point where some atoms are left un-ionized? I have the same question in regards to bases.

I'm not entirely sure of your question? Are you asking if it's possible experimentally and in reality for 100% dissociation? Probably not based on what Dr. Lavelle said. It's near impossible for 100% efficiency for regular dissociation. That's why we round up that strong acids and bases act like they have 100% dissociation because the small error is small enough to not affect calculations much at all. But perhaps at a very precise experimental level, it most definitely would matter How much a specific strong acid dissociates, ratio wise.
The other reason why it's not 100% efficiency is the small chance of potential impurities causing measurement errors.

Although the acid may not be 100% dissociated, in calculations with acids and bases, we act like it is. The dissociation is close enough to 100% to assume that the concentrations of the products are equal to the concentration of the reactant.

It's impossible for it to be 100% dissolved, so we must assume its 100%.

Would there be any cases where we wouldn't assume 100% dissociation and if so what would they be

most acids and bases will not dissociate 100%, but in our course we currently assume they are 100% dissociated.
