Okay, I will "pick" on Duk on this MINOR point:
Duk said:
Take a bottle of vinegar. It's full of water and hydrogen acetate. 1% of the hydrogen acetate dissociates to form acetic acid. Which 1%? Can you point at a specific molecule of hydrogen acetate and say, "That one! That one will dissociate!" Of course not. Some of them will dissociate and the majority won't, and you don't know which ones.
The extent of ionization or dissociation of acetic acid (hydrogen acetate) or any weak acid is measured by Ka, the ionization constant of a weak acid. That value for acetic acid is 1.8 x 10^-5, so it is less that 1%, which (based on my memory) is measured at 25 degrees Celsius. If my math is correct, that works out to 0.4% dissociation, so Duk was not off by MUCH, Well Done, Duk...! I had wrongly assumed that it was MUCH less than 1%.
HOWEVER, Duk's main point about probability anD not knowing WHICH specific molecules of the acid dissociates is still very valid. I think that he he used the 1% as a point of discussion.
supporting evidence:
As an example, glacial acetic acid has an acid dissociation constant of 1.75 x 10-5. A 10 M solution of acetic acid has a percent ionization of only 0.132 %. However, a 0.10 M solution has a percent ionization of 1.32 %.

Glacial acetic acid is a name for water-free (anhydrous) acetic acid. Similar to the German name Eisessig (ice vinegar), the name comes from the ice-like crystals that form slightly below room temperature at 16.6 °C (61.9 °F) (the presence of 0.1% water lowers its melting point by 0.2 °C).
https://en.wikipedia.org/wiki/Acetic_acid#NomenclatureAn interesting "symmetry" to me as that the classic example of the dissociation of a weak base (opposite, chemically, to an acid) is ammonia, NH3, and its Kb is the same numerical value; Kb = 1.8 x 10^-5.
