CAS 590-29-4 poov tshuaj tsim (chko₂)yog cov ntsev poov tshuaj ntawm formic acid. Nws yog dawb, crystalline khoom uas yog soluble heev hauv dej. Qhov kev ua kom siab siab no yog ib qho ntawm cov khoom tseem ceeb uas ua rau cov potassium tsim zoo li siv tau ntau yam siv. Thaum yaj hauv dej, nws ua cov kua ntshiab, xim tsis muaj xim uas hu ua poov tshuaj tsim brine lossis tov.Poov tshuaj zoo li lus tebMuaj qhov tsis tshua muaj qhov taw tes khov thiab muaj qhov siab tshaj - ob tus cwj pwm tseem ceeb rau nws cov kev siv loj.
Puas yog cov poov tshuaj tsim (CAS 590-29-4) lub hauv paus lossis kua qaub?
Poov tshuaj tsim (hosok) yog qhov yooj yimCov. HCOK yog ntsev tsim los ntawm lub hauv paus muaj zog (koh) thiab cov kua qaub tsis muaj zog (formic acid).
Nws yog ntsev uas ua rau cov tshuaj alkaline me ntsis thaum yaj hauv dej. Qhov no yog vim nws yog tsim los ntawm cov kua qaub tsis muaj zog (formic acid) thiab lub hauv paus muaj zog (potassium hydroxide).
Poov Khoom Pa Hluav Taws Xob (CAS 590-29-4) tau ua?
Cov tshuaj powassium yog feem ntau npaj ua txoj hauv kev hauv qab no:
Formic acid reacts nrog potassium hydrocide los tsim cov poov tshuaj tsim:
2hcooh + koh → hosok + h2o
Formic acid reacts nrog poov tshuaj oxide los tsim cov poov tshuaj tsim:
2hcooh + k2o → 2HCOK
