NH4Fe(SO4)2 + K4[Fe(CN)6] 반응

NH4Fe(SO4)2 + K4[Fe(CN)6] 반응

NH4Fe(SO4)2 + K4Fe(CN)6 반응

Preparation of potassium iron(III) hexacyanoferrate(II)

 

---------------------------------------------------

 

NH4Fe(SO4)2 + K4[Fe(CN)6] → KFe2(CN)6 + NH4^+ + 2SO4^2- + 3K^+

NH4Fe(SO4)2 + K4Fe(CN)6 → KFe2(CN)6 + NH4^+ + 2SO4^2- + 3K^+

 

 

 

▶ Ammonium iron(III) sulfate, NH4Fe(SO4)2•12H2O

▶ Potassium hexacyanoferrate(II), K4[Fe(CN)6]•3H2O

▶ Potassium iron(III) hexacyanoferrate(II). K/Fe-Fe(CN)6

= KFe2(CN)6, prussian blue
