Cov hlau oxide liab, hlau oxide dub, hlau oxide xiav, hlau oxide daj, hlau oxide xim av, thiab hlau oxide ntsuab yog sib npaug rau cov hlau oxide pigments. Lawv yog ob qho oxides. Vim li cas cov xim tshwm sim sib txawv? Tsab ntawv xov xwm no yuav txheeb xyuas qhov ze tshaj plaws rau koj Vim li cas cov xim ntawm ob qhov xim-hlau oxide daj thiab hlau oxide ntsuab txawv?
Cov qauv sib txawv molecular ua rau cov xim sib txawv ntawm cov hlau oxide daj thiab hlau oxide ntsuab
Cov tshuaj molecular ntawm cov hlau oxide daj yog Fe2O3, thiab cov muaju feem ntau yog Fe3 thiab O2-; cov roj molecular cov hlau oxide ntsuab yog FeO, thiab cov muaju feem ntau yog Fe2 thiab O2-. Fe3 yog daj, thiab Fe2 yog xim ntsuab. Pom tseeb, qhov sib txawv hauv cov mis molecular ua rau Qhov xim ntawm ob qhov sib txawv.
Hais txog qhov no, qee tus neeg yuav xav tsis thoob. Fe2 yog ntsuab hauv kev daws. Yuav ua li cas nyob rau hauv muaju? Qee cov ntawv sau ntawv hais tias cov mis mos molecular ntawm hlau oxide ntsuab yog cov tshuaj lom neeg nrog cov dej siv lead ua: Fe2O3? H2O, thaum siv los ua cov inorganic xim hlau oxide liab, hlau oxide ntsuab, thiab hlau oxide daj yog txhua yam muaju. Puas yog lawv lub tshuab xim sib txawv vim tias lawv cov qauv siv lead ua?
Ua qhov tseeb, qhov kev muaj peev xwm no tshwm sim, thiab nws muaj qee yam ua rau ligands ntawm Fe2 ntau ceg. Piv txwv, hemoglobin yog xim liab. Cov qauv siv lead ua feem ntau pom tias muaj kev cuam tshuam thiab cuam tshuam, tab sis nws tsis zoo li cuam tshuam rau lub wavelength ntawm photon Lub zog ua kom hloov pauv hluav taws xob qib hluav taws xob tsis pub dhau ntawm Fe2 thiab Fe3, thiab lub zog ntawm lub photon tso tawm los ntawm lub zog hloov qib tau txawv. Vim tias cov xim pom feem ntau yog tias cov xaim hluav taws xob zoo siab los ntawm lub teeb ci thiab tom qab ntawd rov qab los ntawm lub zog hluav taws xob mus rau theem qis zog. Kev nthwv dej ntawm cov duab yees tso tawm yog nyob hauv qhov ntau ntawm tib neeg lub zeem muag, thiab xim yuav pom tau.
