Which substance loses electrons in a chemical reaction
chemical compound changes. Some common redox reactions include fire, rusting of metals, browning of fruit, and photosynthesis. In simpler terms, redox reactions involve the transfer of electrons from one substance to another. In a redox reaction, electrons can never be “lost”; if one substance loses electrons,An oxidation-reduction or redox reaction is a reaction that involves the transfer of electrons between chemical species (the atoms, ions, or molecules involved in the reaction). Redox reactions are all around us: the burning of fuels, the corrosion of metals, and even the processes of photosynthesis and cellular respiration involve oxidation and reduction.Oxidation is an increase in oxidation number (loss of electrons); reduction is a decrease in oxidation number (gain of electrons). 4.7: Oxidation-Reduction Reactions is shared under a not declared license and was authored, remixed, and/or curated by LibreTexts.

Oxidation–reduction reactions, commonly known as redox reactions, are reactions that involve the transfer of electrons from one species to another. The species that loses electrons is said to be oxidized, while the species that gains electrons is said to be reduced. We can identify redox reactions using oxidation numbers, which are assigned ... oxidation number, also called oxidation state, the total number of electrons that an atom either gains or loses in order to form a chemical bond with another atom.. Each atom that participates in an oxidation-reduction reaction is assigned an oxidation number that reflects its ability to acquire, donate, or share electrons.The iron ion Fe 3+, …An oxidizing agent (often referred to as an oxidizer or an oxidant) is a chemical species that tends to oxidize other substances, i.e. cause an increase in the oxidation state of the substance by making it lose electrons.
