Key Aspects of Boiling Vinegar/Water:
Evaporation Process: While water evaporates more readily, acetic acid also vaporizes, resulting in a strong smell of vinegar filling the air.
Concentration: If four cups of vinegar are boiled down to one cup, the resulting liquid is not simply four times as concentrated, because a significant amount of acetic acid also evaporates.
The boiling point of typical household vinegar (4-6% acetic acid) is just above water, at approximately 100.6∘C.
