Macluumaad dheeraad ah oo ku saabsan isla'egta 2NaOH + Cr2O3 → H2O + 2NaCrO2

Waa maxay xaaladda falcelinta ee NaOH (sodium hydroxide) ay kaga falceliso 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 NaCrO2 ()?

Xalka NaOH wuxuu la falgalaa oksaydhka C2O3

Dhacdada ka dib NaOH (sodium 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 NaCrO2, oo muuqda dhamaadka 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.
