Title: Which pungent odor does sodium fluoride usually emit?
Post by: cjemistry888 on April 02, 2025, 02:44:17 AM

For example, the smell of garlic? Is the smell strong? If it is hot in the weather with a temperature of over 30 degrees, will the smell be more obvious? Thank you :P

Sodium flouride has no smell. It's also a salt and its inorganic.
It has nothing to do with garlic, which is organic. This has smell more or less according temperature.

In my anecdotal experience compounds containing sulfur bound to oxygen sometimes smell a little like garlic.  I would be surprised if NaF had any odor.

Same here, especially in the presence of water/humidity. Can't remember what it was though.

From Wikipedia:  "When fresh garlic is chopped or crushed, the enzyme alliinase converts alliin into allicin, which is responsible for the aroma of fresh garlic. Allicin and other thiosulfinates in garlic are unstable and form a number of other compounds, such as diallyl sulfide (DAS), diallyl disulfide (DADS) and diallyl trisulfide (DAT), dithiins and ajoene.[2]". and "Allicin features the thiosulfinate functional group, R-S-(O)-S-R."  I seem to recall other compounds also, but I don't recall what they were.
