Macluumaad dheeraad ah oo ku saabsan isla'egta 3H2O + 2NaOH + Cr2O3 → 2Na[Cr(OH)4]

Waa maxay xaaladda falcelinta ee H2O (biyaha) waxay la falgalaan NaOH (sodium hydroxide) oo la falgala Cr2O3 (chromium(iii) oxide)?

Heerkulka: heerkulka

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 oo u soo saari kartaa Na[Cr(OH)4] ()?

Dhacdada ka dib H2O (biyaha) waxay la falgalaan NaOH (sodium hydroxide) waxay ka falcelisaa 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 Na [Cr (OH) 4], 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.

Macluumaad dheeraad ah oo ku saabsan maaddooyinka isle'egtu isticmaalaan

Falcelinta H2O (nước) la falgal NaOH (natri hidroxit) iyo Cr2O3 (Crom (III) dibi) soo saaro Na[Cr(OH)4] (Sodium tetrahydroxycromate(III)) , xaalada heerkulka Nhiệt độ

Falcelinta soo saarta walaxda H2O (nước) (biyo)

NaOH + C6H5Br → C6H5ONA + H2O + NaBr NH4MAYA2 H 2H2O + N2 Hcl + NaOH → H2O + NaCl

Falcelinta soo saarta walaxda NaOH (natri hidroxit) (sodium hydroxide)

2H2O + 2NaCl → Cl2 + H2 + 2NaOH 2H2O + 2Na → H2 + 2NaOH Ca (OH)2 + NaHCO3 CO CaCO3 + H2O + NaOH

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

2 (NH4)2Crown4 H 5H2O + N2 + 2NH3 + Cr2O3 2NH3 + 2CrO3 H 3H2O + N2 + Cr2O3 (NS4)2Cr2O7 H 4H2O + N2 + Cr2O3

Falcelinta soo saarta walaxda Na[Cr(OH)4] (Sodium tetrahydroxycromate(III)) ()

NaOH + Cr (OH)3 → Na[Cr(OH)4] 3H2O + 2NaOH + Cr2O3 → 2Na[Cr(OH)4]
