1.

Define the terms oxidation and reduction in terms of oxidation number.

Answer»

i. Oxidation is an increase in the oxidation number of an element in a given substance.

e.g. Fe_(s) → \(Fe_{(aq)}^{2+}\)

ii. Reduction is a decrease in the oxidation number of an element in a given substance.

e.g. \(Cu_{(aq)}^{2+}\) → Cu_(s)
