Question

Is K+(aq) +e—> k(s) an example of oxidation

Answer 1

No, the reaction K+(aq) + e- -> K(s) is an example of reduction, not oxidation. In this reaction, potassium ions (K+) gain electrons to form solid potassium (K), which is a reduction process. Oxidation is the loss of electrons, while reduction is the gain of electrons.
