The equation is not complete (products are missing).
Please either complete your equation or click on one of the suggestions below:
Na2S2O3 + I2 = Na2S4O6 + NaI


 화학 방정식을 균형에 대한 지침 :
  • Enter an equation of a chemical reaction and click 'Balance'. 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 PhC2H5 + O2 = PhOH + CO2 + H2O will
  • Compound states [like (s) (aq) or (g)] are not required.
  • If you do not know what products are, enter reagents only and click 'Balance'. In many cases a complete equation will be suggested.
  • Reaction stoichiometry could be computed for a balanced equation. Enter either the number of moles or weight for one of the compounds to compute the rest.
  • Limiting reagent can be computed for a balanced equation by entering the number of moles or weight for all reagents. The limiting reagent row will be highlighted in pink.
