In the reaction between potassium (K) and oxygen (O₂), potassium is oxidized and oxygen is reduced. Potassium loses electrons to form potassium ions (K⁺), while oxygen gains electrons to form oxide ions (O²⁻). This transfer of electrons defines the oxidation and reduction process, where oxidation refers to the loss of electrons and reduction refers to the gain of electrons. Thus, K is the reducing agent, and O₂ is the oxidizing agent in this reaction.
The total reduction potential of a cell can be calculated by subtracting the standard reduction potential of the oxidation half-reaction from that of the reduction half-reaction. For potassium (K) being reduced, the standard reduction potential is approximately -2.93 V, while for copper (Cu) being oxidized, its reduction potential is +0.34 V. Thus, the total reduction potential of the cell is calculated as: E_cell = E_reduction (Cu) - E_reduction (K) = 0.34 V - (-2.93 V) = 3.27 V. This positive value indicates that the cell reaction is spontaneous.
K+
The neutral atom of potassium has the largest radius.
aldosterone
The ionic compound for Potassium is K+ and the ionic compound for Oxide is O2-. So K+ + O2- = K20 From MILLY
-3.27V
The total reduction potential of a cell where potassium is reduced and copper is oxidized can be calculated by finding the difference in the standard reduction potentials of the two half-reactions. The reduction potential for potassium reduction (K⁺ + e⁻ → K) is -2.92 V, and the oxidation potential for copper oxidation (Cu → Cu²⁺ + 2e⁻) is 0.34 V. Therefore, the total reduction potential of the cell is -2.92 V - 0.34 V = -3.26 V.
The ion that carries two negative charges and is isoelectronic with K+ is O2-. Both ions have 18 electrons, but O2- has gained two electrons to achieve a full outer shell, giving it a total charge of -2.

The reaction between potassium hydroxide (KOH) and nickel (Ni) typically results in the formation of potassium nickelate (K2NiO2), along with the release of hydrogen gas. This is a redox reaction where nickel gets oxidized and potassium gets reduced.
