Explanation:
Potassium dichromate iron(II) sulfuric acid (K2Cr2O7 FeSO4 H2SO4) is accessible in nearly every chemical laboratory worldwide. In the H2SO4 medium, K2Cr2O7 and FeSO4 respond mainly. To balance the redox reaction we use the ion-electron technique.
Potassium dichromate reacts in sulfuric acid with iron(II) sulfate
The skeleton reaction of Potassium dichromate and iron(II) sulfate in sulfuric acid (K2Cr2O7 FeSO4 H2SO4) is–
K2Cr2O7 + FeSO4 + H2SO4 = Cr2(SO4)3 + Fe2(SO4)3 + K2SO4 + H2O
Or,
K2Cr2O7 + FeSO4 + H2SO4 = Cr2(SO4)3 + Fe2(SO4)3 + K2SO4 + H2O
