Inhibition reaction??
« on: 10/10/2007 03:09:22 »
Hi

As its known, Na3PO4 is a good inhibitor for the H2O2 decomposition.

¿Can annyone please tell me what is the reaction that takes place?

Thanks

Edit: Yeah, I forgot a P, thank you.

? Maybe you intended  Na3PO4?

I think you may have meant H3PO4.
Anyway, the best reason I can think of is that the phosphate ions form complexes with stuff like Fe that would otherwise decompose the H2O2.

Yes, PO43- is a "sequestrator" (I hope to have translated correcly) for metallic ions who could catalyze H2O2 decomposition.

To Garabato: this means that PO43- forms complexes or insoluble phosphates with metallic ions, preventing them to act as catalysts in the decomposition of H2O2.
