10. Explain how you can use two standard reduction potentials to find the standard cell potential for a cell made from two different electrode materials. How do you know which half-cell undergoes oxidation and which undergoes reduction

Respuesta :

The standard electrode potential of an electrode can be measured by pairing it with the SHE and measuring the cell potential of the resulting galvanic cell. The oxidation potential of an electrode is the negative of its reduction potential.

Half- cell oxidation undergoes reduction :

A half reaction (or half-cell reaction) is either the oxidation or reduction reaction component of a redox reaction. A half reaction is obtained by considering the change in oxidation states of individual substances involved in the redox reaction. Often, the concept of half reactions is used to describe what occurs in an electrochemical cell, such as a Galvanic cell battery.

How do you know which is oxidizing and which is reducing?

Oxidation occurs when the oxidation number of an atom becomes larger. Reduction occurs when the oxidation number of an atom becomes smaller.
