User: Consider the Zn(s) + Cu+2(aq) Zn+2(aq) + Cu(s) system. The electron acceptor is the agent.

Weegy: In addition to precipitation and acid-base reactions, a third important class called oxidation- reduction reactions is often encountered in aqueous solutions. The terms reduction and oxidation are usually abbreviated to redox. [ Such a reaction corresponds to the transfer of electrons from one species to another. A simple redox reaction occurs when copper metal is immersed in a solution of silver nitrate. The solution gradually acquires the blue color characteristic of the hydrated Cu2+ ion, while the copper becomes coated with glittering silver crystals. The reaction may be described by the net ionic equation Cu(s) + 2Ag+(aq) ? Cu2+(aq) + 2Ag(s) (1) We can regard this equation as being made up from two hypothetical half-equations. In one, each copper atom loses 2 electrons: Cu ? Cu2+ + 2e? (1a) while in the other, 2 electrons are acquired by 2 silver ions: 2e? + 2Ag+ ? 2Ag (1b) If these two half-equations are added, the net result is Eq. (1). In other words, the reaction of copper with silver ions, described by Eq. (1), corresponds to the loss of electrons by the copper metal, as described by half- equation (1a), and the gain of electrons by silver ions, as described by Eq. (1b). A species like copper which donates electrons in a redox reaction is called a reducing agent, or reductant. (A mnemonic for remembering this is remember, electron donor = reducing agent.) When a reducing agent donates electrons to another species, it is said to reduce the species to which the electrons are donated. In Eq. (1), for example, copper reduces the silver ion to silver. Consequently the half-equation 2Ag+ + 2e? ? 2Ag is said to describe the reduction of silver ions to silver. Species which accept electrons in a redox reaction are called oxidizing agents, or oxidants. In Eq. (1) the silver ion, Ag+, is the oxidizing agent. When an oxidizing agent accepts electrons from another species, it is said to oxidize that species, and the process of electron removal is called oxidation. ]

Zn losses 2 electrons and converts to Zn² . Cu² gains 2 electrons and converts to Cu. So, the electron acceptor element is copper.
