The standard hydrogen electrode  assigned a potential of 0 volts. The potential of a given electrode measured with respect to the standard hydrogen electrode. Therefore the standard electrode potential is a measure of the potential of a redox reaction.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Calculating_Standard_Reduction_Potential_for_Zinc_Electrode\"><\/span>Calculating Standard Reduction Potential for Zinc Electrode<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Standard reduction potential calculated by subtracting the emf of the cell from the emf of the reference cell. However the reference cell is a cell with a standard electrode potential of zero.<\/p>\n<p>The standard reduction potential for zinc is -0.76 V.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Electrochemical_Series\"><\/span>Electrochemical Series<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>In electrochemistry, the electrochemical series (sometimes called the &#8220;electrode series&#8221;) is a ranking of chemical elements according to their reduction potential. The reduction potential is a measure of the tendency of a chemical species to lose electrons. In other words, it is a measure of the ability of a chemical species to act as an oxidizing agent.<\/p>\n<p>The electrochemical series is based on the half-cell reactions that occur in a battery. In a battery, one half-cell consists of a conductor (such as a metal) that immersed in a solution of ions. The other half-cell consists of a species that is capable of reducing the ions in the first half-cell. The reduction potential is a measure of the tendency of the species in the second half-cell to reduce the ions in the first half-cell.<\/p>\n<p>The electrochemical series can be used to predict the order of reactivity of metals. The most reactive metal is at the top of the series and the least reactive metal is at the bottom. The reactivity of metals can also affected by the presence of other elements. For example, the reactivity of a metal can decreased by the presence of a noble gas.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Uses_of_Standard_Electrode_Potentials\"><\/span>Uses of Standard Electrode Potentials<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<ul>\n<li>Standard electrode potentials used in a variety of ways.
