Macluumaad dheeraad ah oo ku saabsan isla'egta 2KOH + Na2Cr2O7 → H2O + Na2Crown4 + K2Crown4

Waa maxay xaaladda falcelinta ee KOH (potassium hydroxide) waxay la falgashaa Na2Cr2O7 (Sodium dichromate; Sodium bichromate; Dichromic acid disodium cusbo)?

Wax macluumaad ah lagama helin isla'egtan kiimikada ah

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 H2O (biyaha) iyo Na2CrO4 (Sodium chromate; Sodium chromate (VI); Chromic acid disodium cusbo) iyo K2CrO4 ()?

KOH wuxuu ku falceliyaa sodium dichromate

Dhacdada KOH ka dib (potassium hydroxide) waxay la falgashaa Na2Cr2O7 (Sodium dichromate; Sodium bichromate; Dichromic acid disodium cusbo)

Falcelinta KOH (kaliroxitit) la falgal Na2Cr2O7 (Natri dicromat) soo saaro H2O (nước) iyo K2CrO4 (Kali cromat)

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

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

Falcelinta soo saarta walaxda Na2Cr2O7 (Natri dicromat) (Sodium dichromate; Sodium bichromate; Dichromic acid saltdium salt)

H2SO4 + 2Na2Crown4 → H2O + Na2SO4 + Na2Cr2O7 Hcl + 2Na2Crown4 → H2O + 2NaCl + Na2Cr2O7 H2O + 2CO2 + 2Na2Crown4 → 2NaHCO3 + Na2Cr2O7

Falcelinta soo saarta walaxda H2O (nước) (biyo)

NaOH + C6H5Br → C6H5ONA + H2O + NaBr 2 (NH4)3PO4 + 3Ba (OH)2 H 6H2O + 6NH3 + Ba3(PO4)2 Hcl + NaOH → H2O + NaCl

Falcelinta soo saarta walaxda Na2CrO4 (Natri cromat) (Sodium chromate; Sodium chromate (VI); Chromic acid salt salt)

3NaClO + 10NaOH + 2ccl3 H 5H2O + 9NaCl + 2Na2Crown4 2 KOH + Na2Cr2O7 → H2O + Na2Crown4 + K2Crown4 K2Cr2O7 + 2NaOH → H2O + Na2Crown4 + K2Crown4

Falcelinta soo saarta walaxda K2CrO4 (Kali cromat) ()

BaCl2 + H2O + K2Cr2O7 → 2HCl + K2Crown4 + BaCrO4 2 KOH + Na2Cr2O7 → H2O + Na2Crown4 + K2Crown4 K2Cr2O7 + 2NaOH → H2O + Na2Crown4 + K2Crown4
