1. You MUST put in an arrow.
I changes from +5 on the left to 0 on the right.
Ag changes from +1 on the left to +3 on the right for each Ag; howewver, you must have made up a problem because Ag^2+ is not common.
Count up electrons lost and gained for the above, then
Loss of e is oxidation; gain of e is reduction.
The element oxidized is the reducing agent.
The element reduced is the oxidizing agent.
2. HNO3(aq) + NH3(aq) ==> NH4NO3(aq)
net ionic is H^+ + NH3 ==> NH4^+
3. FeCl2==> Fe^2++ 2Cl^-
MgSO4 ==> Mg^2+ + [SO4]^2-
1. 2IO3- + 10Ag+ 12H+I2 + 10Ag++ 6H2O
In the above redox reaction, use oxidation numbers to identify the element oxidized, the element reduced, the oxidizing agent and the reducing agent.
2. Write a net ionic equation for the reaction that occurs when aqueous solutions of nitric acid and ammonia are combined.
3. The following compounds are water soluble. What ions are produced when the compounds are in aqueous solutions? Enter each ion preceded by the number produced upon dissolution.
FeCl2: cation and anion?
MgSO4: cation and anion?
