Which of the following is correct representation of a given molecular equation in ionic form?
K2Cr2O7 + 7H2SO4 + 6FeSO4 → 3Fe2(SO4)3 + Cr2(SO4)3 + K2SO4 + 7H2O
K2Cr2O7 + 7H2SO4 + 6FeSO4 → 3Fe2(SO4)3 + Cr2(SO4)3 + K2SO4 + 7H2O
- Cr2O7 2– + 14H+ + 6Fe2+ → 6Fe3+ + 2Cr3+ + 7H2O
- 2K+ + Cr2O7 2– + 7SO4 2– + 6Fe2+ → 3Fe3+ + SO4 2– + Cr3+ + K+ + 7H2O
- Cr2O7 2– + 2K+ + 7H+ + 6Fe2+ → 6Fe3+ + 6Cr3+ + K+
- Cr2O7 2– + 7H+ + 6Fe2+ → 3Fe2+ + 2Cr3+ + 2K+ + 7H2O
Answer
(A) Cr 2 O 7 2– + 14H + + 6Fe 2+ → 6Fe 3+ + 2Cr 3+ + 7H 2 O
