General Chemistry - Oxidation and Reduction

Flashcards covering key concepts related to oxidation, reduction, and redox reactions as discussed in the lecture.

Oxidation

The process of losing electrons, which results in an increase in oxidation state.

Reduction

The process of gaining electrons, which results in a decrease in oxidation state.

Redox Reactions

Chemical reactions that involve both oxidation and reduction occurring simultaneously.

Oxidizing Agent

The substance that gains electrons and is reduced in a redox reaction.

Reducing Agent

The substance that loses electrons and is oxidized in a redox reaction.

OIL RIG

A mnemonic to remember that Oxidation Is Losing, Reduction Is Gaining electrons.

Net Ionic Equation

An equation that shows only the species that actually change during the reaction, omitting spectator ions.

Spectator Ions

Ions that do not participate in the actual chemical reaction and remain unchanged.

Oxidation State

The hypothetical charge an atom would have if all bonds were completely ionic.

Transition Metals

Elements that can have variable oxidation states and form colored compounds.

Elemental Form

The natural state of a substance where it is not combined with any other elements.
