Qhov sib txawv tseem ceeb ntawm sodium fluoride thiab sodium monofluorophosphate yog tias sodium fluoride muaj sodium cations nrog fluoride anions, whereas sodium monofluorophosphate yog tsim los ntawm sodium, fluorine, phosphorous thiab oxygen atoms.
Ob qho tib si sodium fluoride thiab sodium monofluorophosphate yog ib qho tseem ceeb inorganic compounds uas muaj peev xwm kho cov hniav puas. Yog li ntawd, cov tshuaj no muaj nyob rau hauv ntau hom tshuaj txhuam hniav.
Sodium Fluoride yog dab tsi?
Sodium fluoride yog ib qho inorganic compound, thiab nws muaj cov tshuaj formula NaF. Lub ntsiab lus ntawm cov tshuaj no yog Florocid. Tsis tas li ntawd, nws yog cov khoom tsis muaj xim uas yooj yim yaj hauv dej. Cov molar loj ntawm sodium fluoride yog 41.98 g / mol. Thiab, lub melting point yog 993 ° C, thaum lub boiling point yog 1,704 ° C. Tsis tas li ntawd, cov qauv siv lead ua ntawm sodium fluoride yog lub cubic crystal system.

Ntxiv mus, hais txog nws cov ntawv thov, sodium fluoride yog ib qho tseem ceeb ntawm cov khoom siv tshuaj thiab tshuaj txhuam hniav. Tsis tas li ntawd, nws tuaj yeem tiv thaiv kab noj hniav hauv cov hniav. Qhov sib xyaw no tshwm sim nyob rau hauv daim ntawv ntawm villiaumite, uas yog cov ntxhia tsis tshua muaj. Txawm li cas los xij, nws tuaj yeem ua rau industrially rau nws cov ntawv thov. Peb tuaj yeem tsim cov tshuaj sodium fluoride los ntawm kev nruab nrab ntawm HF acid. Ntawm no, cawv tuaj yeem siv los ua kom NaF. Cov txheej txheem no suav nrog cov tshuaj tiv thaiv ntawm HF thiab NaOH. HF tau txais los ntawm kev tsim cov phosphoric acid los ntawm fluorophosphate los ntawm cov txheej txheem ntub dej.
Tsis tas li ntawd, sodium fluoride muaj sodium cation thiab fluoride anion. Vim muaj cov fluoride ions, cov tshuaj no muaj txiaj ntsig zoo li tshuaj tiv thaiv kab mob hniav los ntawm kev noj cov tshuaj fluoride tsawg. Nws kuj tseem siv los kho cov menyuam yaus hauv thaj chaw uas muaj cov tshuaj fluoride hauv cov dej haus tsawg. NF muaj ntau daim ntawv thov hauv chemistry rau synthesis thiab extractive metallurgy. Tsis tas li ntawd, nws yog siv rau hauv cov organic synthesis cov tshuaj tiv thaiv, ua tus neeg saib xyuas thiab ua tshuaj lom rau cov nroj tsuag noj kab.
Sodium Monofluorophosphate yog dab tsi?
Sodium monofluorophosphate yog ib qho inorganic compound uas muaj cov tshuaj formula Na2PO3F. Cov molar mass ntawm no compound yog 143 g / mol. Thiab, nws yog feem ntau abbreviated li MFP. Tsis tas li ntawd, nws yog ib qho ntsev compound uas tsis muaj xim, tsis muaj ntxhiab, thiab yooj yim yaj hauv dej. Txawm li cas los xij, nws yog insoluble hauv cov kuab tshuaj organic xws li ethanol thiab ether. Nws tshwm raws li cov hmoov dawb thaum tsim industrially. Daim ntawv thov-wise, nws yog ib qho khoom muaj nyob rau hauv cov tshuaj txhuam hniav.
Daim duab 02: Cov Qauv Tshuaj ntawm MFT
Hauv kev tsim khoom lag luam, MFT yog tsim los ntawm cov tshuaj tiv thaiv ntawm sodium fluoride thiab sodium metaphosphate. Tsis tas li, ua lwm txoj hauv kev, nws tuaj yeem tsim los ntawm kev kho tetrasodium phosphate nrog hydrogen fluoride.
Thaum xav txog cov teeb meem hniav lwj, MFT ua raws li cov tshuaj fluoride uas los ntawm cov tshuaj txhuam hniav. Nws tuaj yeem tso cov tshuaj fluoride los ntawm hydrolysis ntawm cov tshuaj. Cov tshuaj fluoride no tuaj yeem tiv thaiv cov hniav los ntawm cov kab mob uas ua rau cov kab noj hniav.
Qhov txawv ntawm Sodium Fluoride thiab Sodium Monofluorophosphate yog dab tsi?
Sodium fluoride thiab sodium monofluorophosphate yog cov khoom xyaw tseem ceeb hauv cov tshuaj txhuam hniav. Qhov sib txawv tseem ceeb ntawm sodium fluoride thiab sodium monofluorophosphate yog sodium fluoride muaj sodium cations nrog fluoride anions, whereas sodium monofluorophosphate yog tsim los ntawm sodium, fluorine, phosphorous thiab oxygen atoms..
Hauv qab infographic tabulates qhov sib txawv ntawm sodium fluoride thiab sodium monofluorophosphate.
Summary – Sodium Fluoride vs Sodium Monofluorophosphate
Sodium fluoride thiab sodium monofluorophosphate yog cov khoom xyaw tseem ceeb hauv cov tshuaj txhuam hniav vim muaj peev xwm kho tau cov kab mob ntawm cov hniav. Qhov sib txawv tseem ceeb ntawm sodium fluoride thiab sodium monofluorophosphate yog sodium fluoride muaj sodium cations nrog fluoride anions, whereas sodium monofluorophosphate yog tsim los ntawm sodium, fluorine, phosphorous thiab oxygen atoms.
