 Instructions on balancing chemical equations:
  • Enter an equation of a chemical reaction and press the 'Balance!' button. The answer will appear below
  • Always use the upper case for the first character in the element name and the lower case for the second character.
     Examples: Fe, Au, Co, Br, C, O, N, F.     Compare: Co - cobalt and CO - carbon monoxide
  • To enter an electron into a chemical equation use {-} or e
  • To enter an ion specify charge after the compound in curly brackets: {+3} or {3+} or {3}.
    Example: Fe{3+} + I{-} = Fe{2+} + I2
  • Substitute immutable groups in chemical compounds to avoid ambiguity.
    For instance equation 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.
  • If you do not know what products are enter regeants only and click 'Balance!'. In many cases a complete equation will be suggested.
 Examples of complete chemical equations to balance:
  • Fe + Cl2 = FeCl3
  • KMnO4 + HCl = KCl + MnCl2 + H2O + Cl2
  • K4Fe(CN)6 + H2SO4 + H2O = K2SO4 + FeSO4 + (NH4)2SO4 + CO
  • C6H5COOH + O2 = CO2 + H2O
  • K4Fe(CN)6 + KMnO4 + H2SO4 = KHSO4 + Fe2(SO4)3 + MnSO4 + HNO3 + CO2 + H2O
  • Cr2O7{-2} + H{+} + {-} = Cr{+3} + H2O
  • S{-2} + I2 = I{-} + S
  • PhCH3 + KMnO4 + H2SO4 = PhCOOH + K2SO4 + MnSO4 + H2O
  • CuSO4*5H2O = CuSO4 + H2O
