Chemical Equation Balancer Cu + KNO3 + H2SO4 = CuSO4 + H2O + K2SO4 + NO

Balanced Chemical Equation

3Cu + 2KNO3 + 4H2SO4 = 3CuSO4 + 4H2O + K2SO4 + 2NO

Reaction Information

Copper + Potassium Nitrate + Hydrogen Sulfate = Copper(ii) Sulfate + Water + Dipotassium Sulphate + Nitric Oxide

Instructions

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 [].
