The spontaneity of redox reactions is demonstrated using copper, zinc, and silver, and their cations. For a particular redox reaction NO2– is oxidized to NO3– and Cu2 is reduced to Cu . In a redox reaction, the reactant that loses electrons (is oxidized) causes a reduction and is called a reducing agent. Example 3: Reaction between Iron and Hydrogen Peroxide. A redox reaction is one in which both oxidation and reduction take place. When does a single replacement reaction occur? Redox: For example, the first one is a redox equation. 1. Instead, it can apply to several different types. Zn is oxidized; Zn is the reducing agent. 2CO+O2 -> 2CO2 Takes place when a more reactive element displaces a less reactive ion from its solution. We can write the individual redox equations: Cu^(2+) + 2e^(-)rarrCu(s) Zn(s) rarr Zn^(2+)+ 2e^(-) A zinc electrode placed in a blue solution of Cu^(2+)(aq) would rapidly acquire a copper … The complete combustion of a hydrocarbon is always redox. CuCl 2 is an oxidizing agent, Zn is a reducing agent. http://www.chemteam.info/Redox/Redox-Rules.html, A trick is to just look for the element in the equation that is paired on one side, but not on the other.
