Add hydrogen peroxide
« on: 16/07/22 08:16 »
How can I add hydrogen peroxide (aqueous H2O2) to an electrolyte solution?

For example in this code:

SOLUTION 1
   temp      25.0
   pH      0.70 charge   
   units      mol/kgw
   density   1.0    calculated
   Cu      0.065
   Fe      0.0004566

If you just want the oxidative effect of adding hydrogen peroxide, you can use REACTION:

Code: [Select]
REACTION 1
H2O2 1
0.1 mmol

You can try to add SOLUTION_MASTER_SPECIES and SOLUTION_SPECIES for H2O2 if you find some thermodynamic data, but I am pretty sure that, in all cases, H2O2(aq) will not exist in appreciable amounts at equilibrium. H2O2 will decompose to H2O and O2 under normal equilibrium conditions.

If you want to kinetically react H2O2, you will need to define a new "element" (like Hperoxide) that you can react with KINETICS (-formula Hperoxide -1 H2O2 +1).
