flyuorid– bir natriy florid, NaF kabi florin bo'lgan ikki elementdan tashkil topgan gidroflorik kislota tuzi.

fluoride– a salt of hydrofluoric acid consisting of two elements, one of which is fluorine, as sodium fluoride, NaF.

formaldegid–odatda, suvli eritmada ishlatiladigan, dezinfektsiyalovchi va konservant sifatida ishlatiladigan, rangli, toksik, potentsial kanserojenik, suvda eriydi, CH2O, odatda oksidlanish orqali metil spirtdan olinadi va turli rezinalar va plastmassalardan.


formaldehyde– a colorless, toxic, potentially carcinogenic, water-soluble gas, CH 2 O, having a suffocating odor, usually derived from methyl alcohol by oxidation: used chiefly in aqueous solution, as a disinfectant and preservative, and in the manufacture of various resins and plastics.
