Consider a iron-silver voltaic cell that is constructed such that one half-cell consists of the iron, fe , electrode immersed in a fe(no3)3 solution, and the other half-cell consists of the silver, ag , electrode immersed in a agno3 solution. the two electrodes are connected by a copper wire. the fe electrode acts as the anode, and the ag electrode acts as the cathode. to maintain electric neutrality, you add a salt bridge separating the two half-cells. use this information to solve parts b, c, and d. part b the half-cell is a chamber in the voltaic cell where one half-cell is the site of the oxidation reaction and the other half-cell is the site of the reduction reaction. type the half-cell reaction that takes place at the anode for the iron-silver voltaic cell. indicate the physical states using the abbreviation (s), (l), or (g) for solid, liquid, or gas, respectively. use (aq) for an aqueous solution. do not forget to add electrons in your reaction. part c the half-cell is a chamber in the voltaic cell where one half-cell is the site of an oxidation reaction and the other half-cell is the site of a reduction reaction. type the half-cell reaction that takes place at the cathode for the iron-silver voltaic cell. indicate physical states using the abbreviation (s), (l), or (g) for solid, liquid, or gas, respectively. use (aq) for an aqueous solution. do not forget to add electrons in your reaction. express your answer as a chemical equation.

Predict the reactants of this chemical reaction. that is, fill in the left side of the chemical equation. be sure the equation you submit is balanced. (you can edit both sides of the equation to balance it, if you need to.) note: you are writing the molecular, and not the net ionic equation. > cacl2(aq) + h20(l)
