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].

Puas yog BaCl2 soluble hauv dej?
Barium chloride yog ib qho ntawm cov ntsev nrov tshaj plaws ntawm barium. Bacl2 hauv dej yog ob qho tib si hygroscopic thiab dej-soluble. Thaum raug nplaim taws, qhov sib xyaw ua kom muaj xim daj-ntsuab. Cov ntsev yog tsim los ntawm reacting hydrochloric acid nrog barium carbonate los yog barium hydroxide
Puas yog Copper II oxide soluble hauv dej?
Zoo insoluble nyob rau hauv dej los yog cawv; tooj liab (II) oxide yaj maj mam hauv cov tshuaj ammonia tab sis sai sai hauv cov tshuaj ammonium carbonate; nws yog yaj los ntawm alkali hlau cyanides thiab muaj zog acid daws; Kub formic acid thiab boiling acetic acid daws tau yooj yim yaj cov oxide
Puas yog acetate manganese soluble hauv dej?
Melting Point: 210 ° C
Puas yog baio3 soluble hauv dej?
Lub decomposition tshwm sim explosively nyob rau hauv kev sib cuag nrog carbon. Sulfuric acid liberates iodine los ntawm barium iodate. Lub solubility, txawm nyob rau hauv dej kub, tsuas yog me me. Hauv 100 grm
Puas yog calcium hydroxide soluble hauv dej?
Dej Ib yam li ntawd, koj tuaj yeem nug, puas yog Ca Oh 2 soluble lossis insoluble hauv dej? Ca (OH ) 2 Nws tsuas yog me ntsis soluble hauv dej (0.16g Ca (OH ) 2 / 100g dej ntawm 20 ° C) tsim cov tshuaj hu ua txiv qaub dej. Lub solubility txo qis nrog nce kub.
