I believe oxygen and hydrogen are always included in a redox reaction. I am basing this conclusion on the fact that, whether these reactions are occurring in a basic solution (add OH- and H20 to balance) or an acidic solution (add H+ and H2O to balance), you use both oxygen and hydrogen in the chemical equation.
Extra info about these fascinating reactions:
After assigning oxidation numbers to the given chemical equation, extract the ones who's oxidation numbers change from the reactants to the products (there should only be two that change). Put these into separate equations with the reactant and its oxidation number and the product and its oxidation for both elements. Then, to equalized the oxidation numbers, add electrons on the appropriate side.
Remember:
Electrons can only be added, but since they have a negative charge, it is like subtracting them. Add electrons to the most positive side of each elements equation. The number of electrons added to either element must be equivalent. To make them so, find the smallest number they both can be divided into (LCD). Multiply each (whole equation) by the number required to make them the LCD.
After which, you can place the new coefficients you found and place them back into the original equation. Then, using conventional methods, you can balance the equation. All element can be balanced this way except for hydrogen and oxygen. Add the appropriate elements (given above), depending on the type of solution, to balance.
Important:
Oxidation is the loss of electrons, when electrons are added to the product. The oxidized element is the ironically referred to as the reducing agent.
Reduction is the gain of electrons, when electrons are added to the reactants. The reduced element is, in turn, referred to as the oxidizing agent.

How do you determine if a reaction is an oxidation-reduction reaction?
An oxidation-reduction reaction can be determined by looking for changes in the oxidation states of the elements involved. If an element loses electrons (oxidation) and another gains electrons (reduction), it is likely an oxidation-reduction reaction.

What do you call a reaction where a substance has gained oxygen?
ok im not shore but i think its called reduction
Part of a reaction that involves only oxidation or reduction is a?
It's not entirely clear what the question is asking... but oxidation involves the loss of electrons from an atom or ion, and reduction involves the gain of electrons. The other parts of a redox (reduction-oxidation) reaction may involve atoms forming and breaking bonds, but the oxidation or reduction part is just about losing or gaining electrons. You might be talking about what is called a "half-reaction." A half-reaction is the part of the reaction that is only either the oxidation step or the reduction step. Neither is a complete reaction, but put together the two half-reactions give the overall reactions. In the oxidation half-reaction, electrons come out as products, and in the reduction half-reaction electrons go in as reactants. Remember: OIL RIG Oxidation Is Loss; Reduction Is Gain.
What chemical process must always accompany a reduction process?
Oxidation is the chemical process that must always accompany a reduction process, as they occur simultaneously in a redox reaction where electrons are exchanged between reactants.
How do you determine if a reaction is an oxidation-reduction reaction?
An oxidation-reduction reaction can be determined by looking for changes in the oxidation states of the elements involved. If an element loses electrons (oxidation) and another gains electrons (reduction), it is likely an oxidation-reduction reaction.
Is it possible to have a reaction in which oxidation takes place but reduction does not?
Oxidation is characterized by the loss of electrons, and reduction is characterized by the gain of electrons. Since there must be an electron loser and an electron receiver, oxidation and reduction are always complimentary.
Electrochemical cells always feature what type of reaction?
Redox or oxidation-reduction reactions.
How do you figure out if a reaction is an oxidation or reduction reaction?
OIL RIG Oxidation is Loss Reduction is Gain... That's all I know =)
What happens during a reduction/oxidation reaction?
An oxidation-reduction (redox) reaction is a type of chemical reaction that involves a transfer of electrons between two species. An oxidation-reduction reaction is any chemical reaction in which the oxidation number of a molecule, atom, or ion changes by gaining or losing an electron
Single reaction where oxidation and reduction take?
half reaction
What is an oxidation reduction or redox reaction?

What is the term for a reaction in which a substances gains electrons?
When a substance gains an electron or electrons, this is known as "reduction". For every reduction reaction, there is also an oxidation reaction. So, whatever substance "gave" the electrons, underwent oxidation.
What occurs at the cathode of a galvanic cell?
An oxidation half-reaction
What is this change in oxidation state called?
This change is called oxidation (increase of ox. state) or reduction (decrease)
