Can someone explain the difference between oxidation and reduction? ALso reducing agent and oxidizing agent?

Certainly! I'd be happy to explain the concepts of oxidation and reduction, as well as the roles of reducing agents and oxidizing agents.
Oxidation: Oxidation is a chemical process that involves the loss of electrons from an atom, ion, or molecule. In this process, the oxidation state (the charge assigned to an atom assuming that all its bonds are ionic) of the element or compound increases. Oxidation usually goes hand in hand with the addition of oxygen or the removal of hydrogen atoms.
Reduction: Reduction is the opposite of oxidation. It involves the gain of electrons by an atom, ion, or molecule. In this process, the oxidation state of the element or compound decreases. Reduction typically involves the addition of hydrogen or the removal of oxygen atoms.
Oxidizing Agent: An oxidizing agent, also known as an oxidant, is a substance that causes another substance to undergo oxidation by accepting electrons. It is itself reduced in the process. Oxidizing agents are usually electron acceptors, such as oxygen, halogens, and certain ions like permanganate (MnO4-) or dichromate (Cr2O7^2-). They are characterized by their tendency to take electrons from other substances.
Reducing Agent: A reducing agent, also called a reductant, is a substance that causes another substance to undergo reduction by donating electrons. It is itself oxidized in the process. Reducing agents are electron donors, and commonly include metals like zinc (Zn), hydrogen gas (H2), or certain ions like sulfite (SO3^2-) or hydrosulfite (HSO3-).
In summary, oxidation is the loss of electrons, while reduction is the gain of electrons. Oxidizing agents accept electrons, causing other substances to oxidize, whereas reducing agents donate electrons, causing other substances to reduce.
Remember the mnemonic "OIL RIG," which stands for "Oxidation Is Loss (of electrons), Reduction Is Gain (of electrons)."
