What does the phenomenon of the reaction between metallic lithium and chloride-water mean?
There were components such as Cl2 and ClCl3 in the water. Metallic lithium is an active metal. When reacting with water, the first reaction of lithium with hydrogen is to form lithium chloride-based alloy (Mn + Cl2 = Mn). At the same time, the reaction of lithium with hydrogen is to form lithium chloride-based alloy (Mn + Cl2 = Mn + Cl2 + Mn). The reaction phenomenon was that the color of the chloride-water quickly faded, and tiny bubbles appeared on the surface of the strip. Read more exciting novels for free
Analysis of the reaction phenomenon of dropping excessive amount of chloride-water into the solution of soda
1. * * Reaction equation and analysis of material properties ** - The composition of the water was complex. It contained Cl2, Cl2, and HClO. When the solution of Na2CO3 was mixed with water, the first reaction was: Cl2 + 2Na2CO3 + H2O = NaClO + NaClO +2NaHCO3. - Because of the participation of the Cl2 in the reaction, the yellowish-green color of the Cl2 water would gradually fade. - Gas was generated during the reaction because of the formation of CO2 (When the amount of Cl-water was excessive, the subsequent formation of Cl-and-NaHCO3 reacted with each other), so bubbles were observed. 2. * * Analysis of the change in the acidic and acidic properties of the solution ** - The solution of soda ash was basic. As the water was added, the reaction formed substances such as NaClO, NaHCO3, and so on. The basicity of the solution gradually weakened. - When there is an excess of Cl-water, the solution will eventually become acidic due to the large amount of Cl-water. 3. * * Impact analysis of hypochloric acid ** - Hypochloric acid has strong oxidisation and bleachability, but in this reaction system, the main reaction phenomenon is still determined by the reaction between Cl2 and Na2CO3 and the subsequent reaction between Cl2 and Na2HCO3. The effect of hypochloric acid is not obvious on the phenomenon, but mainly on the chemical properties of the solution. For example, it will produce an oxidisation effect on some reducing substances in the solution. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Reaction equation and phenomenon of chloride-carbon dioxide
If the two did not react, the reaction equation could not be written. carbon dioxide (CO2) was a non-metallic oxide-like substance, while Cl2 was a non-metallic elemental substance. A substitution reaction occurred between the compound and the elemental substance. However, this kind of reaction required the compound to be a dissolved metal compound or acid, while CO2 was a non-metal compound, which did not meet the conditions, so the two did not react. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What is the reaction phenomenon of chloride-silver nitrates?
It was very difficult for the permethlene to react with the silver nitrates, and there was almost no obvious reaction. Because the reaction of the silver dimmer with the alcohol solution of silver nitrates was more difficult, it was more difficult to decompose the chloride-ester in water, and the intermediate product of the reaction, CH2 =CH·, was difficult to form, which was more difficult to react with silver nitrates than other halaloids. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reaction Phenomenon of Copper Chloride-Ammine Solution
Cuprous chloride-bound to nitrogen can form a complex with nitrogen. When cuprous chloride-bound is added to concentrated nitrogen, copper ions will coordinate with nitrogen molecules to form diamminocuprous complex ions, and the solution will become a colorless solution. The reaction equation is [CuCl2 + 2NH2·H2 O = 2H2 O+(Cu2 (NH2) 2) Cl2]. However, this ion is relatively stable, but after a period of time, the oxygen in the air will vaporize the copper (I) into copper (II), and the solution will turn dark blue. The reaction equation is: 4(Cu(NH2) 2)+8NH2 +O 2 + 2H 2 O = 4(Cu(NH2) 2 +40H). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What does the reaction phenomenon of the reaction between the soda ash and the non-metallic gas mean?
The reaction of soda with different non-metallic gases was different: - The reaction between carbon dioxide and carbon dioxide was as follows: 2NaOx + CO2 = Na2CO3 + H2O. There was no obvious experimental phenomenon in the reaction. - The reaction between the two was a disproportionate reaction, but no specific reaction phenomenon was mentioned. - The reaction between sulfur dioxide and sulfur dioxide was 2NaOx + SO2 = Na2SO3 + H2O, and the reaction phenomenon was not mentioned. - The reaction between sulfur dioxide and sulfur dioxide is 2NaOx + SO3 = Na2SO4 + H2O. The reaction phenomenon is not mentioned. - The reaction equation was Si +2NaOx + H2O = Na2SiO3 + 2H2. Gas was produced. However, it did not react with other non-metallic gases such as carbon dioxide and nitrogen dioxide. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reaction equation and phenomenon of iron chloride-alcohol heating
The reaction between FeClCl2 and alcohol (C2H20H) under heating was more complicated, and it was generally believed that alcohol would be oxided by FeCl2. The reaction equation was: 6C H Oh + 4FeCl → 4Fe6CHCHO +12HQ +3H O (This reaction was only a possible reaction, and there may be many side reactions in the actual reaction). Phenomenon: The color of the solution may change because the iron chloride-based solution itself is brownish-yellow. Due to the formation of new substances during the reaction, the color may become lighter or other color changes may occur. If iron is formed, black solid substances may appear (but if the amount of iron formed is small, it may not be easy to observe). At the same time, there may be a pungent smell (because of the formation of substances such as Zhang). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reaction equation of chloride-red phosphorus and explanation of phenomenon
The reaction between red phosphorus and Cl2 would result in two reactions. The first reaction is the reaction of red phosphorus with Cl2 to form phosphorous tri-(2P +3Cl2) [2PCl3], and the phosphorus trichosphate was a colorless liquid; the phosphorus trichosphate then reacted with the Cl2 to form phosphorus pentachloride (<br><br>"<br>" 2PCl3 ", and the phosphorus trichosphate was a colorless liquid; the phosphorus trichosphate then reacted with the Cl2 to form phosphorus pentachloride (<br>" PCl3 + Cl2 "<br>" stacking " Phosphorous pentachlorides was a white solid. During the reaction process, the white solid particles of phosphorus pentachlorinate formed smoke, and the colorless liquid droplets of phosphorus tricolor formed fog, so the reaction phenomenon was white smoke. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What is the reaction phenomenon of adding iron chloride-Na?
When the solution was added to the solution, the first reaction would be between the solution and the water. The solution would then dissolve into a bright ball, which would then swim around on the surface of the liquid and make a squeaking sound. At the same time, it formed a mixture of the two, which then reacted with iron chlorideto form a reddish brown floccule deposit of iron dioxide. The chemical equation of the reaction is: 2Na +2H ^O = 2NaOx + H ^, FeClCl2 + 3NaOx = FeCl2 + 3NaOx +3NaCl2. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
