Chemical Equation Balancer H3PO4 + H2S + K2Cr2O7 = K3PO3 + CrPO4 + S8 + H2O

Balanced Chemical Equation

64H3PO4 + 88H2S + 24K2Cr2O7 = 16K3PO3 + 48CrPO4 + 11S8 + 184H2O


To balance a chemical equation, enter an equation of a chemical reaction and press the Balance button. The balanced equation will appear above.

  • Use uppercase for the first character in the element and lowercase for the second character. Examples: Fe, Au, Co, Br, C, O, N, F.
  • Ionic charges are not yet supported and will be ignored.
  • Replace immutable groups in compounds to avoid ambiguity. For example, C6H5C2H5 + O2 = C6H5OH + CO2 + H2O will not be balanced, but XC2H5 + O2 = XOH + CO2 + H2O will.
  • Compound states [like (s) (aq) or (g)] are not required.
  • You can use parenthesis () or brackets [].
