KMnO4 + FeSO4 + H2SO4 → MnSO4 + K2SO4 + Fe2(SO4)3 + H2O

  • KMnO4 + FeSO4 + H2SO4 → MnSO4 + K2SO4 + Fe2(SO4)3 + H2O
  • Mn+7 + 5ē → Mn2+
  • Fe2+ - 1ē → Fe3+
  • Mn+7 + 5ē → Mn2+ 1 yamasa 2 ion alinsa
  • Fe2+ - 1ē → Fe3+ 5 yamasa 10 ion aliw kerek
  • 2KMnO4 + 10FeSO4 + 8H2SO4 → 2MnSO4 + K2SO4 + 5Fe2(SO4)3 + 8H2O
  • Elektron balans usili.

KJ + K2Cr2O7 + H2SO4 → J2 + Cr2(SO4)3 + K2SO4 + H2O Bul sxemani ionli formada jazamiz:

  • KJ + K2Cr2O7 + H2SO4 → J2 + Cr2(SO4)3 + K2SO4 + H2O Bul sxemani ionli formada jazamiz:
  • J- + Cr2O7²- + H+ → 2Cr³+ + H2O + J2
  • Cr2O7²- + 6ē + 14 H+ → 2Cr³+ + 7 H2O
  • 2J- - 2ē → J2 6________3
  • Cr2O7²- + 6ē + 14 H+ → 2Cr³+ + 7 H2O 2 2__________ 1
  • Ion – elektron usili.
  • Cr2O7²- + 6ē + 14 H+ → 2Cr³+ + 7 H2O
  • 6J- + Cr2O7²- + 14 H+ → 3J2 + 2Cr³+ + 7 H2O
  • 6KJ + K2Cr2O7 + 7H2SO4 → 3J2 + Cr2(SO4)3 + 4K2SO4 + 7H2O
  • Cu+2
  • +2e
  • Cu
  • Diqqatin'iz ushin raxmet!
