Qhov sib txawv tseem ceeb ntawm mercuric thiab mercurous yog lub sij hawm mercuric yog siv los piav txog cov tebchaw uas muaj Hg(II) cations, whereas lo lus mercurous yog siv los piav txog cov tebchaw uas muaj Hg(I) cations.
Mercury yog cov khoom siv hlau. Nws yog cov kua hlau ntawm chav tsev kub. Mercury polycation yog ib lo lus siv los hu ua polyatomic cations ntawm mercury chemical element. Cov piv txwv feem ntau yog mercuric cation thiab mercurous cation.
Mercuric yog dab tsi?
Lo lus mercuric txhais tau tias, "muaj Hg(II) cations". Peb tuaj yeem muab cov tshuaj formula ntawm cov cation no li Hg2+Yog li ntawd, mercuric cation muaj ib tug + 2 net zoo nqi. Tsis tas li ntawd, peb tuaj yeem hais tias nws tus lej oxidation yog 2 (lossis, ntau dua qhov tseeb II). Nws yog divalent cation. Muaj ntau lub tebchaw uas muaj cov cation no. Cov tshuaj sib xyaw ua ke no muaj npe siv lub npe "mercuric" - piv txwv li, mercuric chloride. Peb siv cov npe sib txawv kom paub txog qhov cation no, piv txwv li. mercuric ion, mercuric cation, mercury ion (Hg2+), mercury (II) ion, mercury (+2), thiab lwm yam
Cov mercuric ion belongs rau chav kawm ntawm cov tshuaj inorganic tshuaj sib xyaw uas peb tuaj yeem faib ua homogeneous hloov pauv hlau sib txuas. Cov tebchaw no yog cov tshuaj inorganic uas muaj cov hlau atoms xwb. Ntawm no, lub atom loj tshaj plaws yog kev hloov pauv hlau atom.
Daim duab 01: Mercury Chemical Element
Nyob hauv tib neeg lub cev, mercuric ions tuaj yeem kuaj pom hauv cov kua dej sib txawv xws li tso zis, ntshav, kua cerebrospinal, thiab lwm yam. Ntxiv rau cov no, peb tuaj yeem soj ntsuam mercuric ions hauv ntau yam khoom noj xws li cloves, spelt, hickory. txiv ntseej, tis taum, thiab lwm yam. Txawm li cas los xij, mercuric chemical compounds paub tias yog cov tshuaj lom.
Mercurous yog dab tsi?
Lo lus mercurous txhais tau tias "muaj Hg (I) cations". Qhov no yog qhov zoo tshaj plaws-paub polycation ntawm mercury. Peb tuaj yeem muab cov tshuaj formula ntawm no cation li Hg22+ Ntawm no, mercury atom muaj tus lej oxidation 1. Yog li ntawd, peb tuaj yeem ua tau. cais nws raws li ib tug monovalent cation.
Qhov ion no suav tias yog thawj cov hlau cation uas tau lees paub los ua homogeneous hloov pauv hlau sib txuas. Tsis tas li ntawd, cov lus ua ntej "mercurous-" yog siv los sau cov tshuaj lom neeg uas muaj cov cation no.
Hauv cov tshuaj aqueous, cov mercurous ion ruaj khov. Ntawm no, nws tshwm sim nyob rau hauv equilibrium nrog elemental mercury thiab mercuric ion. Peb tuaj yeem hloov pauv nws qhov sib npaug los ntawm kev ntxiv ib qho anion uas tuaj yeem tsim cov ntsev tsis txaus Hg (II) xws li mercuric sulfide. Hom kev sib xyaw no tuaj yeem ua rau qhov tsis txaus ntseeg ntawm cov ntsev mercurous.
Qhov txawv ntawm Mercuric thiab Mercurous yog dab tsi?
Cov feem ntau cov polycations ntawm mercury yog mercuric thiab mercurous cations. Lo lus mercuric hais txog lub ntsiab lus, "muaj Hg (II) cations" thaum lub sij hawm mercurous hais txog lub ntsiab lus, "muaj Hg (I) cations". Yog li ntawd, qhov sib txawv tseem ceeb ntawm mercuric thiab mercurous yog lub sij hawm mercuric yog siv los piav txog cov tebchaw uas muaj Hg(II) cations whereas lo lus mercurous yog siv los piav txog cov tebchaw uas muaj Hg(I) cations.
Hauv qab infographic qhia ntau cov ntsiab lus ntawm qhov sib txawv ntawm mercuric thiab mercurous.
Summary – Mercuric vs Mercurous
Mercury yog cov khoom siv hlau. Nws tuaj yeem tsim cov cations sib txawv npe hu ua polycations. Mercuric thiab mercurous yog ob yam cations ntawm mercury. Qhov sib txawv tseem ceeb ntawm mercuric thiab mercurous yog lub sij hawm mercuric yog siv los piav txog cov tebchaw uas muaj Hg(II) cations whereas lo lus mercurous yog siv los piav txog cov tebchaw uas muaj Hg(I) cations.
