Lintlha tse ling mabapi le equation 2Br2 + 8NaOH + CrBr2 → lihora tse 42O + Na2CrO4 + 6NaBr

Ke eng e sebetsanang le boemo ba Br2 (bromine) ha NaOH (sodium hydroxide) e arabelana le CrBr2 (Chromium(II) bromide; Chromium(II) dibromide) ?

Sethothetsi: NaOH

Tlhaloso: Maemo a loketseng a tikoloho bakeng sa karabelo, joalo ka mocheso, khatello, li-catalysts, le solvent. Li-Catalysts ke lintho tse potlakisang lebelo (lebelo) la karabelo ea lik'hemik'hale ntle le ho jeoa kapa ho fetoha karolo ea sehlahisoa sa pheletso. Li-catalyst ha li na phello maemong a tekano.

Lits'ebetso li ka etsahala joang 'me tsa hlahisa H2O (metsi) le Na2CrO4 (Sodium chromate; Sodium chromate(VI); Chromic acid disodium salt) le NaBr (sodium bromide) ?

Br2 e itšoara ka CrBr2 tikolohong ea NaOH

Phenomenon kamora hore Br2 (bromine) e sebetsane le NaOH (sodium hydroxide) e sebetsana le CrBr2 (Chromium(II) bromide; Chromium(II) dibromide)

Tekano ena ha e na tlhahisoleseling efe kapa efe e mabapi le ketsahalo.

Maemong ana, o hloka feela ho sheba ho bona hore na ntho ea sehlahisoa ke eng NaBr (sodium bromide), e hlahang qetellong ea karabelo.

Kapa haeba ho na le e 'ngoe ea lintho tse latelang tse sebetsang MOKHATLO (Chromium (II) bromide; Chromium (II) dibromide), ea nyamela

Ke lintlha life tse ling tsa bohlokoa tseo u lokelang ho li tseba mabapi le karabelo

Ha re na lintlha tse ling mabapi le ts'ebetso ea lik'hemik'hale tsena.

Ketso ea Br2 (brom) arabela ka NaOH (natri hidroxit) 'me CrBr2 (Crom (II) bromua) lihlahisoa H2O (s) 'me NaBr (Natri bromua) , sethothetsi boemo NaOH

Karabelo e hlahisang ntho Br2 (brom) (bromine)

8H2SO4 + 2KMnO4 + 10NaBr → 5Br2 + 8H2O + 2MNSO4 + 5Na2SO4 + K2SO4 2AgBr → 2Ag + Br2 Cl2 + 2NaBr → Br2 + 2NaCl

Ketso e hlahisang NaOH (natri hidroxit) (sodium hydroxide)

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