Question
Use the table 'Standard Reduction Potentials' located in the 'Tables', to predict if a reaction will occur when Fe metal is put into a 1M aqueous Cd2+ solution.
If a reaction will occur, write a balanced net ionic equation for the reaction. If no reaction will occur, leave all boxes blank.
___ + ___ ------> ___+ ___
Use a table of Standard Reduction Potentials to predict if a reaction will occur between Cd metal and F2(g), when the two are brought in contact via standard half-cells in a voltaic cell.
If a reaction will occur, write 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.
___+ ___ ------> ___+ ___
Enter electrons as e-. Use smallest possible integer coefficients. If a box is not needed, leave it blank.Explanation / Answer
1) net reaction:
Fe(s) + Cd+2 (aq) ------------> Fe+2 (aq) + Cd (s)
2) net reaction :
Cd (s) + F2 (g) --------------------------> 2 F - (aq) + Cd+2 (aq)
explanation :
these reactions are based on standard reduction potential . Fe reduction potential lower tha Cd reduction potential so
Fe will be oxidised
Cd+2 will be reduced
in the second probelm
F2 will be reduced and Cd will be oxidized . F2 is very good oxidizing agent and Cd is reducing agent
these answer based on standard reduction potentails which are in standard table you can find
