Problems for week 12 discussion 2. In the reaction shown below, wrtie in the oxidation states of all atoms. _________ is the oxidizing agent and _________ the reducing agent. Zn(s) + H 2 SO 4 (aq) H 2 (g) + ZnSO 4 (aq) When cadmium metal and the Fe(III) ion are mixed in aqueous solution, a solution containing Cd(II) and Fe(II) results. Write a balanced redox equation for this process. 1. 3. 4. CuO( s ) reacts with NH 3 ( aq ) to yield N 2 ( g ) and Cu( s ) in a redox reaction. Which reactant is oxidized? Write a balanced ½ reaction for the oxidation of that reactant in acidic solution. Which reactant is reduced? Write a balanced ½ reaction for the reduction of that reactant in acidic solution. Write a balanced overall equation for the reaction of CuO( s ) with NH 3 ( aq ). Will the presence of NH 3 ( aq ) in the above reaction result in a basic or an acidic solution? 5. Balance the following redox equation in acidic solution: Zn(s) + NO 3 - (aq) Zn 2+ (aq) + NO(g) Balance the following redox equation in basic conditions: Mn(OH) 2 ( s ) + MnO 4 - ( aq ) MnO 2 ( s )
