Determining Oxidation States

Let's determine the oxidation states for the given chemical compounds:

1. FeCl3 2. P2O5 3. H2SO3 4. Al2O3 5. NaOH 6. K2SO4 7. MgO 8. Zn(OH)2

Oxidation States

1. FeCl3: The oxidation state of Fe in FeCl3 is +3. Chlorine typically has an oxidation state of -1 in its compounds. Therefore, the oxidation state of Cl in FeCl3 is -1. 2. P2O5: The oxidation state of P in P2O5 is +5. Oxygen typically has an oxidation state of -2 in its compounds. Therefore, the oxidation state of O in P2O5 is -2. 3. H2SO3: The oxidation state of H in H2SO3 is +1. The oxidation state of S in H2SO3 is +4. The oxidation state of O in H2SO3 is -2. 4. Al2O3: The oxidation state of Al in Al2O3 is +3. The oxidation state of O in Al2O3 is -2. 5. NaOH: The oxidation state of Na in NaOH is +1. The oxidation state of O in NaOH is -2. The oxidation state of H in NaOH is +1. 6. K2SO4: The oxidation state of K in K2SO4 is +1. The oxidation state of S in K2SO4 is +6. The oxidation state of O in K2SO4 is -2. 7. MgO: The oxidation state of Mg in MgO is +2. The oxidation state of O in MgO is -2. 8. Zn(OH)2: The oxidation state of Zn in Zn(OH)2 is +2. The oxidation state of O in Zn(OH)2 is -2. The oxidation state of H in Zn(OH)2 is +1.

These oxidation states are determined based on the rules of assigning oxidation states to elements in chemical compounds.
