Question

Use the References to access important values if needed for this question. for this question. Enter electrons as e Use smallest possible integer coemcients. If a box is not needed, leave it blank. Use a table of Standard Reduction Potentials to predict if a reaction will occur between n metal and Br20, when the two are brought in contact via standard half-cells in a voltaic cell. If a reaction will occur, a balanced net ionic equation for the reaction, assuming that the product ions are in aqueous solution. If no reaction will occur, leave all boxes blank.

Explanation / Answer

Br2 + 2e-   -------------> 2Br-                           (1.08)

Zn             ----------------> Zn2+  + 2e-              (0.763)                                                                                                (Please note the sign in the reduction potential above table, Zn2+ reduction is -0.763 whereas in the above oxidation reaction, ie Zn become Zn2+ is +0.763 )

So, from above reduction potentials Br2 is having the higher reduction potential, so it will reduce and Zn will oxidize as follow the reaction,

Zn + Br2   -----> ZnBr2

pls put the above reaction in the box.
