Thread Content
This post was last edited by “Back to Cambridge” on February 5, 2016, at 17:05. Starting today, the Chemical Engineering Theory section will launch the “Question of the Day” activity to help everyone reinforce their basic knowledge in chemical engineering. Subsequently, series such as “Fundamentals of Chemical Engineering”, “Mass Transfer and Separation”, “Chemical Thermodynamics”, and “Chemical Process Technology” will also be introduced. We hope for your active participation! Wishing you all a Merry Christmas~~ For replies to the “Question of the Day” activity, answers can be viewed directly; however, the thread will be closed after one day! ! To encourage continued participation from everyone this year! You get 3 wealth rewards just for participating, and an additional 4 wealth points for correct answers~~~ Short answer question: What is a redox reaction? Answer: During a reaction, when the oxidation numbers of atoms or ions in the reactants change or electrons are transferred, such a reaction is called an oxidation-reduction reaction. The process in which the oxidation number increases (or electrons are lost) is known as oxidation, while the process in which the oxidation number decreases (electrons are gained) is known as reduction.
A chemical reaction in which the oxidation states of elements change accordingly before and after the reaction
What is a redox reaction? Answer: A redox reaction is a chemical reaction in which the oxidation numbers of elements change accordingly before and after the reaction. A chemical reaction in which the oxidation states of elements change during the reaction is called an oxidation-reduction reaction. This reaction can be understood as consisting of two half-reactions, namely an oxidation reaction and a reduction reaction. Such reactions all obey charge conservation. In redox reactions, oxidation and reduction must occur in equal amounts simultaneously. The two can be likened to the relationship between yin and yang, where they rely on each other, transform into one another, fluctuate in strength, and are also opposed to one another. Redox reactions also exist in organic chemistry.
An oxidation-reduction reaction (also known as a redox reaction) is a type of chemical reaction in which the oxidation state of elements changes before and after the reaction. The essence of redox reactions is the gain or loss of electrons, or the shift of shared electron pairs. Copied directly from Baidu; P

A redox reaction is a chemical reaction in which the oxidation state of a certain element changes before and after the reaction. This reaction can be understood as consisting of two half-reactions, namely an oxidation reaction and a reduction reaction. The essence of a reaction is a change in oxidation states, that is, the transfer and shift of electrons. The oxidation state increases, that is, the half-reaction involving the loss of electrons is an oxidation reaction ； A decrease in oxidation number, along with the gain of electrons, is a reduction reaction. A substance whose oxidation state increases reduces the other substance, while itself gets oxidized; therefore it is called a reducing agent, and its product is known as an oxidation product ； A substance whose oxidation state decreases oxidizes another substance while being reduced itself; therefore it is called an oxidizing agent, and its product is known as a reduced product. That is: Reducing agent + Oxidizing agent ---> Oxidation products + Reduction products.
