Color Change of Colloidal Solution from the Reaction of NaSiO4 and HNO3
The reaction between the acid and the acid was to form a sulfuric acid deposit. The reaction equation was Na 2 SiO2 +2HNO2 == H 2 SiO2 +2NaNO2. No colloid solution was formed, so the color of the colloid solution did not change. Read more exciting novels for free
Reaction of the solution with the solution
There were different opinions on whether or not the reaction between the two substances occurred. One view was that silver chloride-soda would react to produce silver-white silver silver precipitations and NaCl2, and the silver-white precipitations could easily be converted to brown silver oxide-soda. The other view was that the reaction could not be carried out because the reaction between base and salt required the salt to be dissolved, while AgCl2 was difficult to dissolve. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reaction of Acid and Solution
The reaction of sulfuric acid with different solutions was different: - During the reaction between the solution of sulfuric acid and the solution of the solution of - The acid reacted with rust (mainly composed of iron dioxide), dissolving and removing the rust. After the reaction, the solution turned yellow. - When sulfuric acid reacted with iron trioxid, reddish-brown floccule precipitations were dissolved to form a yellow solution; when sulfuric acid reacted with copper trioxid, blue precipitations were dissolved to form a yellow-green solution; when sulfuric acid reacted with copper dioxide, black solid was dissolved to form a yellow-green solution. - Gas was formed when the acid reacted with the metal, and it reacted with the metal. When the acid reacted with iron, the solution turned light green and released gas. When the acid reacted with aluminum, gas was formed. - When the solution is dropped into a solution (not specified) and vibrated while dropping, it may start to drop without any phenomenon. When a certain substance in the solution is basically transformed into another substance, gas will start to escape continuously (because the composition of the solution is not specified, only one possibility is provided). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Is there a reaction between the solution of the lead and the solution of the lead?
The reaction between the solution of the two metals would result in the formation of the two metals, namely, the sulfuric acid and the sulfuric acid. The color of the solution gradually changed from green to bright blue. The reaction equation was: Mn +2CrCl2 = Mn +2CrCl2, and the ion equation of the reaction was: Mn +2Cr3 === Mn +2Cr2 (because of the order of metal activity: Mn> Mn). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reaction of Silicate in the Solution of Alkaline
The chemical equation for the reaction between silicon and a solution of soda is: Si +2NaOx + H ^O = Na ^SiOx +2H ^^. In this reaction, water is the oxidiser. Silicate was a chemical element with the chemical symbol Si, while soda was a highly corrosive and highly basic chemical compound with the chemical formula of NaOx. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reaction equation of the solution of silver nitrates added to the solution of vinylene
It was very difficult for the reaction between the two solutions to occur, and there was no reaction equation. Due to the existence of p-pi in the double bond, the C-Clbond length was shortened and the bond energy was increased. It was difficult for the Cl-atom to leave, so it was difficult to react with the silver nitrates. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The solution to the blackening of the color of the bittern
If the salt water was black but not bad, it could be diluted to change the color back. The specific operation was to add water according to the degree of blackness of the bittern until the color faded. After adding water, he weighed the brines, checked the amount, seasoned them, and re-mixed the spices. If the bittern is too dark, it can be diluted in 2 - 3 times. After each time, add water to dilute it. The amount of water added should not exceed half of the weight of the bittern. Otherwise, it is better to start a new pot of bittern. At the same time, after the treatment of the bittern, it was necessary to avoid the cause of the blackening of the bittern and prevent it from blackening again.

Reaction of CaCl3 and NH4Cl4 Solution
When the reaction between the carbon dioxide and the solution of the nitrogen dioxide was carried out, it would produce calcium chloride-water-nitrogen and carbon dioxide. During the reaction process, bubbles could be observed. At the same time, due to the formation of hydrogen, the smell of hydrogen could be smelled. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reaction of Butyne and Copper Ammine Solution
In the case of Butyne, the reaction of 1 -Butyne with the copper halide in an aminium solution would produce a red deposit. This was because the copper halide in an aminium solution must have a carbon-carbon triple bond, and it was the triple bond at the end of the chain, not the triple bond in the middle of the chain. As for the reaction of 2-Butyne with the copper aminium solution, there was a view that the reaction of 2 -Butyne with the copper aminium solution would produce 2 -Butyne. The reason was that 2 -Butyne had an active molecular structure and would lose electrons to form a new chemical bond. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reaction of Sulfuric Acid Solution with Esters
Esters can be subjected to a reaction of either acid or base. In an acidic environment, the ester's decomposition was irreversible, and sulfuric acid acted as a catalyst. Although the catalyst participated in the chemical reaction, its mass and chemical properties remained unchanged during the reaction, and it returned to its initial state after the reaction ended. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
How to adjust the reaction rate of the solution?
The solution reaction rate could be adjusted from the following aspects: 1. ** The nature of the reagent (internal factor)**: This is the main factor that determines the reaction rate. Different substances have different reaction activities, so the reaction rate will also be different. 2. ** Solution Concentration (External Cause)**: Increase the concentration of the reagent, and the reaction rate will increase. 3. ** Temperatures (External Cause)** - As for the irreversible reaction, the positive and reverse reaction rates increased with the increase of temperature, but the increase of the heat absorption reaction rate was greater. 4. ** Pressure (External factor, for reactions involving gases)** - When the other conditions remained unchanged, increasing the pressure would reduce the volume of the gas, increase the concentration, and accelerate the reaction rate. - For a reaction where the volume changes before and after the reaction, the side with a large number of gaseous substances in the equation has a large degree of influence on the reaction rate by the pressure (when the pressure is increased, it increases to a large extent; when the pressure is reduced, it decreases to a large extent). - The reason for the change in pressure and the effect of this change on the concentration of the reaction system should be distinguished to determine the effect on the reaction rate. For example: - At a constant temperature: increase the pressure → decrease the volume → increase the concentration → increase the reaction rate. - At constant temperature and volume: fill in the gas reagent → increase in concentration → increase in rate; fill in the "noble gas" → increase in total pressure, but the partial pressure of each gas remains unchanged, that is, the concentration of each substance remains unchanged, and the reaction rate remains unchanged. - At a constant temperature and pressure: fill in the "noble gas" → increase in volume → decrease in the concentration of each reaction substance → slow down the reaction rate. 5. ** catalyst (external factor)**: The catalyst can reduce the activation energy of the reaction, increase the percentage of activated molecules, and increase the speed of the forward and reverse reactions to the same extent. 6. [Other conditions (external factors): Light, particle size of the reagent, the state of the reagent, and so on can affect the chemical reaction rate.] For example, grinding made the particles of the reagents smaller, increasing the contact area between the reagents, thereby increasing the reaction rate. For some reactions, specific reagents may affect the reaction rate. The state of the reagents (such as solid, liquid, and gaseous) may be different, and the reaction rate may be different. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
