Redox reactions involve electron transfer between reactants. Oxidation occurs when electrons are lost, reduction when electrons are gained. Oxidizing agents accept electrons, reducing agents donate electrons
Oxidizing agent gains electrons from reducing agent in redox reactions. Can be electron acceptor or transfer electronegative atoms to substrate. Common examples include oxygen, hydrogen peroxide, and halogens
Redox reactions involve changes in oxidation states of reactants. Oxidation is electron loss, reduction is electron gain. Redox processes occur simultaneously and cannot occur independently
Equivalent weight is the mass of one substance that combines with another. Element equivalent weight equals atomic weight divided by valence. Acid-base equivalent weight supplies one mole of hydrogen ions. Redox equivalent weight supplies one mole of electrons
Oxidation occurs when atoms, molecules, or ions lose electrons. Oxidation increases the oxidation state of chemical species. Oxidation doesn't necessarily involve oxygen
Oxidation is the loss of electrons during chemical reactions. Reduction is the gain of electrons during chemical reactions. Oxidation can occur spontaneously or artificially
