What is the possibility of reducing costs?
The half-cell or complete cell reaction's reduction potential is also known by the redox or oxidation/reduction pot. It is a measure of the tendency for molecules (or even atoms or ions) to become reduced. It measures the tendency of molecules to acquire electrons, and therefore be reduced.
What exactly is oxidation/reduction? When electrons are stripped, this is called oxidation. Reduction refers to the act of receiving or gaining electrons. This is when, for example, an antioxidant donates an electron.
What does it all mean in terms a reduction potential? A solution that has a higher potential will be more likely to acquire electrons (be reduced), while one with a lower potency will lose electrons. It is important to note that a high potential for reduction does not mean that the reaction will occur. The reaction still requires some activation Energy.
It is difficult to quantify the absolute potential for a solution. This is why reduction potentials can be defined relative to a reference electrode.
The standard reduction possibility is the redox potentia measured under standard conditions. This includes 25 degC, activity equal 1 per ions, pressure of 1bar per gas and participation in the reaction. The standard potential for reduction is determined relative to a hydrogen electrode standard (SHE), an arbitrarily given potential of 0 V.
What is the cell potential equation?
Nernst equation is a cell potential equation that links the reduction potential to the standard electropotential,
temperature, as well as the activities of molecules.
levels can substitute for activities to get an approximate result. The Nernst equation works for half-cell and full cell reactions.
