Any chemical reaction between air and vinegar?

[oem7110]

If I place a glass of white vinegar on the table, and let it make contact with air,
Does anyone have any suggestions on what kind of chemical reaction has between air and vinegar?
Thanks in advance for any suggestions

Basically none. Simple evaporation will be a dominating process.

A good way to preserve vinegar is to pickle it in vinegar.
