person Posted April 17, 2009 Share Posted April 17, 2009 Hey im having trouble understanding all the mechanisms of the following !! " A dry cell is contained in a zinc housing that acts as the anode. the other electrode, the cathode, is a graphite rod in the middle of the cell. a layer of manganese oxide and carbon black surounds the graphite rod, and a thick paste of ammonium chloride and zinc chloride serves as the electrolyte. The cell reactions are: Zn(s)-> Zn^2+ + 2 e^- 2MnO2(s) + 2NH4^+ + 2 e^- -> Mn2O3(S) + 2NH3(aq)+ H2O Pls explain: 1. the role of all the chemicals (those directly involved and what the carbon black does). 2. .... Cant remember Thanx !!!! Link to comment Share on other sites More sharing options...
