Dej: H2S yog soluble hauv dej kev daws teeb meem tab sis tuaj yeem nthuav tawm ntawm cov theem dej ntau lossis tsim cov sulfides thiab lwm cov tshuaj sulfur.

Hais txog qhov no, puas yog h2s aqueous?

Yog li, H2S yog hydrosulfuric acid, es tsis yog hydrosulfic acid, raws li lub npe "sulfide" yuav qhia. Lub compound, H2S , npe hydrogen sulfide thaum nws yog nyob rau hauv daim ntawv ntshiab tab sis nws yog hu ua hydrosulfuric acid thaum nws acidic zog nyob rau hauv dej kev daws teeb meem raug tham.

Ib yam li ntawd, lub cev molecular ntawm h2s yog dab tsi? khoov

Hauv qhov no, yog h2s khov lossis aqueous?

Dej: H2S yog soluble hauv dej kev daws teeb meem tab sis tuaj yeem nthuav tawm ntawm cov theem dej ntau los yog tsim cov sulfides thiab lwm cov sulfur-muaj cov sib txuas.

H2s tuaj yeem tua koj sai npaum li cas?

Tuag ua tau tshwm sim hauv 1 mus rau 4 teev tom qab kis tau. Tshaj 500 tam sim poob ntawm kev nco qab. Kev tuag yog sai, qee zaum tam sim. H2S theem ntawm 100 ppm thiab siab dua yog suav tias yog tam sim ntawd txaus ntshai rau lub neej thiab kev noj qab haus huv (IDLH).
