Specification ntawm Disodium oxalate CAS 62-76-0
Nqe lus piav qhia:
Sodium oxalate, los yog disodium oxalate, yog sodium ntsev ntawm oxalic acid nrog cov mis Na2C2O4. Nws feem ntau yog dawb, crystalline, tsis muaj ntxhiab hmoov, uas decomposes ntawm 250-270 degree.
Disodium oxalate tuaj yeem ua raws li tus neeg sawv cev txo qis, thiab nws tuaj yeem siv los ua tus qauv tseem ceeb rau kev daws teeb meem poov tshuaj permanganate (KMnO4).
Cov ntxhia hauv daim ntawv ntawm sodium oxalate yog natroxalate. Nws tsuas yog tsis tshua pom muaj thiab txwv tsis pub muaj kev ntxhov siab heev ntawm ultra-alkaline pegmatites.
Synonyms:
Ethanedioic acid, disodium ntsev;
disodium, oxalate;
Daim ntawv thov:
Nws yog tsuas yog siv los ua ib qho nruab nrab rau kev tsim cov oxalic acid, thiab tseem tuaj yeem siv los ua tus neeg sawv cev tanning thiab cov npog ntsej muag rau kev ua tawv tawv, uas tuaj yeem txhim kho cov alkali tsis kam ntawm cov complex. Nws tsis yooj yim rau precipitate thiab yog siv raws li ib tug siv rau calibration ntawm poov tshuaj permanganate tov nyob rau hauv analytical chemistry. Siv raws li ib tug daj pyrotechnic illuminator. Siv los ua cov khoom siv rau kev ntsuas cov tshuaj poov tshuaj permanganate. Nws kuj yog ib tug hlau precipitating tus neeg saib xyuas, txo tus neeg sawv cev, complexing neeg sawv cev, masking agent.
