Hi,

I was wondering can anyone help me find the relevant Oxidation and Reduction half reactions so I can incorporoate Nernst equation to model a feeback control. I have data on the following:

pH, Temperature, ORP (mV) reading.

I would like to calculate /etimate Free available Chlorine within 20% accuracy.

I understand that NaOCl + H2O => NaOH and HOCl.

HOCl <> H+ OCl-

E = Eo -RT/NF 2.303 Log 10(Oxidants /reactants)

platinum ORP electrode and reference electrode of Ag/AgCl.

Can anyone help me please?
