Inorganic Unit 10 + Practice for Exam

Oxidation is

Loss of electrons (increase in charge/ oxidation state)

Reduction is

Gain of electrons (decrease in charge/ oxidation state)

The oxidant/oxidizing agent…

> Allows oxidation of the other reagent by accepting electrons
> Undergoes reduction itself

The reductant/reducing agent…

> Allows for reduction of the other reagent by supplying electrons
> Undergoes oxidation itself

Volts (V) =

Potential Energy/Charge = J/C

True or False: Electrons spontaneously move from high to low potential

True

Which of the following electronic transitions would give the stronger UV-Vis signal?
-MC (d→d)
-MLCT

MLCT

If [Co(NH3)6]Cl2 is orange, then what color would you expect for [Ir(NH3)6]Cl3

yellow

Describe what happens during MLCT excitation

Electrons jump from metal d orbitals to ligand pi orbitals if the split is lower. This can result in a higher spin and higher paramagnetism,

What are two metals that are susceptible to oxidation by oxygen in air?

cadmium, tin. iron, copper, nickel, cobalt, gold, platinum, silver
