I am trying to write a balanced (redox) equation for C4H4O6(2-) + H2O2

I know the half eqn for H2O2
H2O2 + 2H(+) + 2e(-) => 2H2O

I am trying to figure out the tartrate half - have looked on the internet for 2 hours now!!!! I know that CO2 is a product but not sure about what else.  Does anyone else know???

Thanks!! Belinda

H₂O and CO₂.

This one have to be done using half-equations approach, do not even try to use oxidation numbers.

Thanks for that!!!! My balanced eqn then is

C4H4O6(2-) + 5H2O2 + 2H(+) => 4CO2 + 8H2O

Is that right??

Seems OK.
