Macluumaad dheeraad ah oo ku saabsan isla'egta 2KOH + Cr2O3 → H2O + 2KCrO2

Waa maxay xaaladda falcelinta ee KOH (potassium hydroxide) ee uu la falgalo Cr2O3 (chromium(iii) oxide)?

Xaaladda Kale: isugeyn

Sharaxaad: Xaaladaha deegaanka ugu fiican ee falcelinta, sida heerkulka, cadaadiska, kicinta, iyo dareeraha. Catalysts waa walxo deddejiya xawaaraha (xawaaraha) falcelinta kiimikaad iyada oo aan la isticmaalin ama aan ka mid noqon badeecada dhamaadka. Kataliyayaashu wax saameyn ah kuma laha xaaladaha dheellitirka.

Sidee falcelintu u dhici kartaa una soo saari kartaa H2O (biyaha) iyo KCrO2 (Potassium Chromate(III))?

Dhacdada KOH ka dib (potassium hydroxide) waxay la falgashaa Cr2O3 (chromium(iii) oxide)

Isle'egtani ma hayso macluumaad gaar ah oo ku saabsan ifafaalaha.

Xaaladdan oo kale, waxaad u baahan tahay oo keliya inaad fiiriso si aad u aragto haddii walaxda sheyga KCrO2 (Kaliumotaatiyamka Chromate (III)), oo ka muuqda dhammaadka falcelinta.

Ama haddii mid ka mid ah walxaha fal-celinta soo socda Cr2O3 (chromium (iii) oksaydh), oo la waayo

Waa maxay macluumaadka kale ee muhiimka ah ee ay tahay inaad ka ogaato falcelinta

Ma hayno macluumaad dheeraad ah oo ku saabsan falcelintan kiimikaad.

Falcelinta KOH (kaliroxitit) la falgal Cr2O3 (Crom (III) dibi) soo saaro H2O (nước)

Falcelinta soo saarta walaxda KOH (kali hidroxit) (kaydka hydroxide)

2NaOH + K2HPO4 → 2 KOH + Na2HPO4 H2O + K2O → 2KOH 3C2H4 + 4H2O + 2KMnO4 → 2 KOH + 2mno2 + 3C2H4(Oh)2

Falcelinta soo saarta walaxda Cr2O3 (Crom (III) oxit) (chromium (iii) oxide)

2NH3 + 2CrO3 H 3H2O + N2 + Cr2O3 2 (NH4)2Crown4 H 5H2O + N2 + 2NH3 + Cr2O3 O2 + 4Cr (OH)2 H 4H2O + 2Cr2O3

Falcelinta soo saarta walaxda H2O (nước) (biyo)

Hcl + NaOH → H2O + NaCl 2H2S + 3O2 H 2H2O + 2SO2 H2SO4 + Na2SO3 → H2O + Na2SO4 + SO2
