I have to stop the ozonation of the wastewater with sodium thiosulfate. I am asking for a balance:
O3 + Na2S2O3 = ?
Thank you kindly.

is this the reaction to be balanced?
Na
2S
2O
3 + O
3 = SO
3 + Na
2O
2 📖
balanced reaction:
3 Na
2S
2O
3 +
5 O
3→6SO
3 +
3 Na
2O
2 📖
However, please wait for confirmation from someone more experienced than me.

Please dont write products if you don't know what is going on.
Thiosulfat will be go to sulfate
S2O3 2- + 10 OH- => 2 SO4 2- + 5 H2O + 8 e-
Ozon will be to normal oxygen
O3 + H2O + 2 e- => O2 + 2 OH-

Thank you very much
))) Can you help me and write the equation in nonionic form?
Na
2S
2O
3+O
3+?=Na
2SO
4+ O
2+?

I think with the given equations you can develop by yourself. Add both equations so that the electrons will be erased,.

Thiosulfat will be go to sulfate
S2O3 2- + 10 OH- => 2 SO4 2- + 5 H2O + 8 e-
Ozon will be to normal oxygen
O3 + H2O + 2 e- => O2 + 2 OH-
Second equation multiply by 4
4 O
3 + 4 H
2O + 8 e- => 4 O
2 + 8 OH-
Addition
S
2O
3 2- + 10 OH- +4 O
3 + 4 H
2O + 8 e- => 2 SO
4 2- + 5 H
2O + 8 e- + 4 O
2 + 8 OH-
Simplefy
S
2O
3 2- + 2 OH- + 4 O
3 => 2 SO
4 2- + H
2O + 4 O
2
Add Na+
Na
2S
2O
3 + 2 NaOH + 4 O
3 => 2 Na
2SO
4 + H
2O + 4 O
2
Finished

O3 + Na2S2O3
From this equation, the thiosulphate from sodium thiosulphate (Na2S203) will go to sulfate.
S2O3 2- + 10 OH- → 2 SO4 2- + 5 H2O + 8 e-
The ozone in the equation (O3) will be converted to normal Oxygen O2
4 (O3 + H20 + 2 e- → O2 + 2 OH-)
By adding both these equations. We get:
S2O3 2- + 10 OH- + 4 O3 + 4 H2O + 8 e- → 2 SO4 2- + 5 H2O + 8 e- + 4 O2 + 8 OH-
Further simplification would be:
S2O3 2- + 2 OH- + 4 O3 → 2 SO4 2- + H2O + 4 O2
After the addition of sodium, the products are sodium sulfate, water, and Oxygen.
The final balanced equation is:
Na2S2O3 + 2 NaOH + 4 O3 → 2 Na2SO4 + H2O + 4 O2
