tooj liab (I) sulfide , Cu2S, [22205-45-4], MW 159.15, yog ib txwm tshwm sim raws li xiav lossis grey ntxhia chalcocite, [21112-20-9]. tooj liab (I) sulfide los yog tooj liab glance yog insoluble nyob rau hauv dej tab sis decomposes nyob rau hauv nitric acid thiab concentrated sulfuric acid.

Hauv qhov no, CuS yog soluble hauv dej?

Qhov ntau ntawm cov compound yog tau los ntawm cua sov cupric sulfide (CuS) nyob rau hauv ib tug kwj ntawm hydrogen. Cuprous sulfide yog insoluble hauv dej tab sis soluble hauv ammonium…

CuCl puas yaj hauv dej? tooj liab (I) tshuaj chloride , feem ntau hu ua khob chloride , yog qhov qis tshuaj chloride tooj liab, nrog rau cov mis CuCl. Cov khoom yog cov khoom dawb dawb soluble hauv dej, tab sis soluble heev hauv cov concentrated hydrochloric kua qaub.

Ib yam li ntawd, tib neeg nug, yog cu2o soluble hauv dej?

Xyaum insoluble hauv dej thiab organic solvents. Soluble nyob rau hauv aqueous daws ntawm ammonia thiab nws cov ntsev. Soluble nyob rau hauv dilute hydrochloric acid, tsim cuprous chloride, uas yaj nyob rau hauv ntau acid. Nrog dilute sulfuric los yog nitric acids, cupric ntsev yog tsim thiab ib nrab ntawm cov tooj liab yog precipitated raws li cov hlau.

Puas yog Cu2S khoom?

Siv ab initio molecular dynamics, peb qhia tau hais tias kev siv zog kawm Cu2S siab chalcocite theem yog ua tau ib khov kho -kua hybrid theem uas muaj nyob rau hauv qhov kub thiab txias (> 105 C). Thaum kub siab (piv txwv li, 700 C), cov anion sublattice ntawm cov superions yog yaj ua kua [1].
