Nickel oxide yog soluble hauv kua qaub , potassium cyanide, thiab ammonium hydroxide. Nws yog insoluble nyob rau hauv ob qho tib si txias thiab kub dej , thiab cov tshuaj caustic. Daim ntawv dub ntawm npib tsib xee oxide yog tshuaj reactive, whereas ntsuab nickel oxide daim ntawv yog inert thiab refractory.
Tom qab ntawd, ib tus tuaj yeem nug, puas yog nickel oxide soluble hauv dej?
Nickel oxide yog cov hmoov ntsuab ntsuab uas ua daj ntawm cua sov. Nws yog ib qho nyuaj rau kev npaj cov compound no los ntawm tsuas yog cua sov npib tsib xee nyob rau hauv oxygen thiab nws yog yooj yim dua tau los ntawm cua sov npib tsib xee hydroxide, carbonate los yog nitrate. Nickel oxide yog nkag tau soluble nyob rau hauv acids tab sis insoluble hauv kub thiab txias dej.
Qhov thib ob, yog nickel oxide aqueous? Nws raug cais raws li cov hlau yooj yim oxide . Ob peb lab kilograms yog tsim nyob rau hauv sib txawv zoo txhua xyoo, feem ntau raws li ib tug intermediate nyob rau hauv zus tau tej cov npib tsib xee alloys.
Nickel (II) oxide.

Tom qab ntawd, ib tug kuj yuav nug, yog nickel soluble los yog insoluble?
Solubility ntawm nickel thiab nickel compounds Nickel chloride yog feem ntau dej soluble; 553 g / L ntawm 20oC, rau 880 g / L ntawm 99.9oC. Nickel carbonate muaj a dej solubility ntawm 90 mg / L, thaum lwm cov nickel compounds, xws li npib tsib xee oxide, npib tsib xee sulfide thiab nickel tetra carbonyl yog dej insoluble.
Puas yog nickel iodide soluble?
Nickel (II) iodide yog ib qho inorganic compound nrog cov qauv NiI2. Cov khoom no paramagnetic dub dissolves nkag rau hauv dej muab xiav-ntsuab kev daws teeb meem ntawm aquo complexes.

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 tooj liab oxide soluble hauv sulfuric acid?
Reacting tooj liab (II) oxide nrog sulfuric acid. Nyob rau hauv qhov kev sim no ib qho insoluble hlau oxide reacted nrog ib tug dilute acid los ua ib tug soluble ntsev. Tooj liab (II) oxide, cov khoom dub, thiab tsis muaj xim dilute sulfuric acid react los tsim tooj liab (II) sulfate, muab cov xim xiav xim rau cov tshuaj
Puas yog mercury oxide soluble?
Lus Txhais rau liab mercuric oxide (2 ntawm 2) ib tug me ntsis crystalline, dej-soluble, tshuaj lom compound, HgO, tshwm sim raws li ib tug ntxhib, txiv kab ntxwv-liab hmoov (liab mercuric oxide) los yog nplua, txiv kab ntxwv-daj hmoov (daj mercuric oxide. ): siv tseem ceeb raws li ib tug pigment nyob rau hauv cov xim thiab raws li ib tug antiseptic nyob rau hauv pharmaceuticals
Puas yog bismuth oxide acidic lossis alkaline?
Bismuth oxide yog suav hais tias yog ib qho yooj yim oxide, uas piav qhia txog kev ua haujlwm siab nrog CO2. Txawm li cas los xij, thaum acidic cations xws li Si (IV) tau qhia hauv cov qauv ntawm bismuth oxide, cov tshuaj tiv thaiv nrog CO2 tsis tshwm sim
Puas yog mercuric oxide yog qhov sib xyaw lossis cov khoom?
Mercury (II) oxide yog lwm qhov sib xyaw; Nws muaj cov ntsiab lus mercury thiab oxygen, thiab thaum cua sov nws decomposes rau cov ntsiab lus. Cov tshuaj sib txawv ntawm cov khoom sib xyaw uas cov ntsiab lus hauv cov khoom sib xyaw ua ke los ntawm cov ntawv cog lus tshuaj thiab tsis tuaj yeem sib cais los ntawm qhov sib txawv ntawm lawv lub cev
