What is a reduction potential
The reason for this becomes clear when we look at the standard reduction potentials (E°) and calculate the oxidation-reduction potential (ORP). The sum of the half reaction potentials, 0.76 and 0.34 V, gives an ORP of 1.10 V in standard conditions. Because 1.10 V is positive, this indicates that the reaction is favorable and occurs spontaneously.If the standard reduction potential of lithium is very negative, then the oxidation potential of lithium ion is very positive. If it is uphill to transfer an electron from hydrogen to lithium cation, it must be downhill to transfer an electron from a lithium atom to a proton. After all, hydrogen is more electronegative than any of the alkalis.Water conservation refers to any beneficial reduction of water usage, loss or waste. It also includes the strategies and activities to manage and protect water resources to meet the demand for human consumption.
