Let’s practice… Determine the oxidation numbers for the atoms in the compound NaCl.
Determine which atom will have a positive or negative oxidation number.
Check whether the oxidation numbers add up to the overall charge
Determine which atom will have a positive or negative oxidation number by looking at the electronegativity values.
Determine the oxidation number of sulfur by using the fact that the oxidation numbers of the atoms must add up to the charge on the molecule
Determine the oxidation states of the elements K and Br on both the reactant and product side of the following reaction: 2K + Br2 →2KBr
In the product determine which atom will have a positive or negative oxidation number by looking at the electronegativity values
Use the valency of the elements in the product to determine the oxidation numbers.
Check whether the oxidation numbers add up to the charge on the compound
Redox Reactions Reduction-Oxidation
Half-reaction The oxidation or reduction reaction part of a redox reaction. It is obtained by considering the change in oxidation states of the individual substances that are involved in the redox reaction
Oxidation is the loss of electrons and leads to an increase in oxidation number Reduction is the gain of electrons and leads to a decrease in oxidation number OILRIG Oxidation Is Loss of electrons and Reduction Is Gain.
