What is the reduction potential
The potential of a half-reaction measured against the SHE under standard conditions is called the standard electrode potential for that half-reaction.In this example, the standard reduction potential for Zn 2 + (aq) + 2e − → Zn(s) is −0.76 V, which means that the standard electrode potential for the reaction that occurs at the anode, the ...Oxidation reduction potential probes, at the entry level, can be extremely inexpensive. Industrial grade ORP probes can cost significantly more, because of the sensitivity of the liquids they have to measure. Drinking water should have an ORP between 600 to 700 mV. The ideal ORP for hydroponics is between 300 to 500 mV.Risk avoidance is an approach that eliminates any exposure to risk that poses a potential loss.
