Oxidation and reduction reactions occurred simultaneously in a single oxido-reduction reaction. It could not simply be said that either of the reactions was heat absorbing. Oxidation-reduction reactions could be both heat absorbing and heat releasing. For example, the combustion reaction was an oxido-reduction reaction and was an exhalation reaction, while the formation of water gas was an absorption reaction. Read more exciting novels for free
Metal smelting was mostly an oxido-reduction reaction. In the process of metal smelting, when reducing agents such as carbon, carbon dioxide, and hydrogen react with metal oxides at high temperatures, the reducing agent will undergo an oxidization reaction (the chemical valency will increase and the electrons will be lost), and the metal elements in the metal oxides will undergo a reduction reaction (the chemical valency will decrease and the electrons will be obtained). For example, the thermal reduction method was used to smelt metals. It used a reducing agent with strong thermal reduction properties to reduce the metal from its compound. It was an oxido-reduction reaction that followed the conservation of lost and gained electrons. The coke reduction method, carbon dioxide reduction method, hydrogen reduction method, active metal reduction method, etc. all involved oxido-reduction reactions. In the ancient silver refining process, the cellar mass needed to go through a reduction process (melting silver into lead), and then go through an oxidization process (separation of lead and silver) to obtain raw silver. The oxidization reaction here was the reaction of lead in the furnace ash, separating lead from silver. It was also the embodiment of the principle of the oxidoreduction reaction in metal smelting. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Air oxidization was a chemical reaction in which the reagents lost electrons. The oxygen value increased during the oxidization and decreased during the reduction. In the reaction of organic matter, the introduction of oxygen or the removal of oxygen from organic matter is called oxidization, and vice versa is reduction. Air oxidization is affected by many factors: 1. In terms of concentration, the higher the concentration of the solution, the stronger the solute's oxidization and reduction. 2. In terms of temperature, the higher the temperature of a substance, the stronger its oxidisation or reduction properties. 3. In terms of pH-value, acidic conditions could enhance the oxidisation ability of the oxidiser and facilitate the assimilation reaction; neutral and basic conditions would weaken the oxidisation ability and facilitate the dismutation reaction. 4. In terms of the catalyst, the use of the catalyst first affected the reaction rate. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
In the electrolyser, the oxidization reaction referred to the reaction process that occurred at the positive pole connected to the power supply. During this process, the negative ions moved towards the positive pole, where they lost their electrons. For example, in some electrolysers, after the ions from the ions reach the positive pole, they will lose their electrons and turn into other substances. This process of losing electrons is called an oxidization reaction. The working principle of the electrolyser was based on the oxido-reduction reaction. The oxido-reduction reaction and the oxido-reduction reaction occurred at the same time at the yin and yang poles. The oxido-reduction reaction was an important part of the entire electrolyser process. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Most of the chemical reactions were exothermic, because the chemical reaction was a bond formation process, and the bond formation process was exothermic. However, there were also some chemical reactions that were xenothermic, such as C + CO2 = 2CO2. Most of the decomposition reactions were heat-absorbing reactions because the process of the decomposition reaction was a bond breaking process, and the bond breaking process was an heat-absorbing process. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
In the case of a revertible thermal reaction, the chemical reaction constant was a positive function of temperature. The higher the temperature, the faster the reaction speed. However, increasing the temperature in a revertible thermal reaction had a contradictory effect. On the one hand, as the positive reaction proceeded, the system would release heat and the temperature would increase, and the reaction would speed up. On the other hand, the reverse reaction would also speed up as the temperature increased, which would weaken the positive reaction. Therefore, there was an optimal temperature at which the reaction rate was the greatest. This temperature was called the optimal temperature. In the case of the industrial synthesis of hydrogen, which was an example of a reversibility, from the perspective of increasing the reaction rate and increasing the content of hydrogen, the actual industrial production used a temperature of 400 - 500 ° C, and the iron catalyst was the most active at around 500 ° C. In addition, in order to make the overall reaction speed and conversion rate of the irreversible exothermic chemical reaction process fast, a temperature segment control scheme can be used to make it change according to the optimal conversion rate temperature curve trajectory. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
During the metal smelting process, the reducing agent would undergo an oxidisation reaction to produce an oxided product. When carbon, carbon dioxide, hydrogen, and the like were used as reducing agents to react with metal oxides at high temperatures, the reducing agent's valency would rise, and it would lose electrons, causing an oxidization reaction to occur, resulting in an oxided product. For example, when hydrogen was used to reduce metal compounds, the hydrogen's chemical valency would rise to become water, and water would be the oxided product. However, different smelting reactions would produce different products, which needed to be determined according to the specific reaction process and the reagents and products. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The reduction reaction and addition reaction in organic chemistry were interlinked. The reduction reaction mainly referred to the deoxidization or dehydration reaction of organic compounds. The addition reaction was a reaction in which the saturated carbon atoms in the organic molecules directly combined with other atoms or atomic groups to form new substances. In organic chemistry, some reactions were both reduction reactions and addition reactions, such as the dehydration reaction. There were also many addition reactions that were not hydrogen addition, such as the hydrating reaction (the radical addition) or the addition with a halo. These were all addition non-reduction reactions. There was also the deoxidization reaction of organic matter, which was a reduction reaction but not an addition reaction. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The term " negative potential " refers to the change in the negative potential caused by the flow of a negative current. During the process of the polar reduction, a reduction reaction would occur at the interface. This was because the polar reduction would cause the potential of the metal to shift negatively. When the equilibrium potential of the metal's oxido-reduction reaction was reached, the corrosion of the metal would be inhibited. This process was based on the principle of the polar reduction in electrochemistry, and the polar reaction in the polar reduction process was the reduction reaction. Therefore, the reduction reaction would be accelerated by the negative pole. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
