Oxidizing agent or oxidant

In the same way that acid-base reactions involve the transfer of protons between proton donors and proton acceptors, redox reactions involve the transfer of electrons between electron donors, called reducing agents or reductants, and electron acceptors, called oxidizing agents or oxidants. Thus when a redox reaction takes place, a reductant loses electrons and is oxidized to its conjugate oxidaut ... 

The species that gains electrons is reduced and acts as the oxidizing agent (or oxidant). (In short, reduced = oxidizing agent.)... 

Free energy is released as electrons are transferred along the electron transport chain from an electron donor (reducing agent or reduc-tant) to an electron acceptor (oxidizing agent or oxidant). The (electrons can be transferred in different forms, for example, as hydride ions ( FT) to NAD+, as hydrogen atoms (-H) to FMN, coenzyme Q, and FAD, or as electrons (-e ) to cytochromes. 

Oxidation. There are 10 types of oxidative reactions in use industrially (80). Safe reactions depend on limiting the concentration of oxidizing agents or oxidants, or on low temperature. The following should be used with extreme caution salts of permanganic acid hypochlorous acid and salts sodium... 

Redox reactions involve oxidation and reduction they occur by the exchange of electrons between reacting chemical species. Electrons (or electron density) are lost (or donated) in oxidation and gained (or accepted) in reduction. An oxidizing agent (or oxidant), which accepts electrons (and is thereby reduced), causes oxidation of a species. Similarly, reduction results from reaction with a reducing agent (or reductant), which donates electrons (and is oxidized). 

Oxidation and reduction steps complement one another, e.g. in reaction 7.1, magnesium is oxidized, while oxygen is reduced. Magnesium acts as the reducing agent or reductant, while O2 acts as the oxidizing agent or oxidant.

When a substance B emits electrons, it leaves behind a new substance D. B is referred to as the reducing agent (or reductant) (abbreviation Rd) and D as the oxidizing agent (or oxidant) (abbreviation Ox). We use the abbreviations Rd and Ox for any type of particle whether it is positive, neutral, or negative, freely mobile in a solution or in a gas, or is only a component in a crystal. The simplest form of electron donation can be expressed as follows ... 

INTRODUCTION AND SECTION 20.1 In this chapter we have focused on electrochemistry, the branch of chemistry that relates electricity and chemical reactions. Electrochemistry involves oxidation-reduction reactions, also called redox reactions. These reactions involve a change in the oxidation state of one or more elements. In every oxidation-reduction reaction one substance is oxidized (its oxidation state, or number, increases) and one substance is reduced (its oxidation state, or number, decreases). The substance that is oxidized is referred to as a reducing agent, or reductant, because it causes the reduction of some other substance. Similarly, the substance that is reduced is referred to as an oxidizing agent, or oxidant, because it causes the oxidation of some other substance. 

If substance A causes the oxidation of substance B, substance A is called the oxidizing agent or oxidant. Thus, in Eq. (6.3), Ag (aq) is the oxidant, because it causes Cu(s) to lose electrons (note that the... 

The two essential reactants in a redox reaction are given special names to indicate the roles they play. The species that removes electrons is referred to as an oxidizing agent, or oxidizer the species from which the electrons are removed so reduction can occur is called a reducing agent, or reducer. For example, in Equation 19.5,...
