What is the reaction phenomenon of adding sulfuric acid to the preparation of FeCl3?
Ferric acid reacted with sulfuric acid to form a light green solution, which was because the product was a hydratable iron ion. If there was more of it, it would produce chloride-ions, and the solution would turn yellow. Moreover, the addition of sulfuric acid would suppress the decomposition of iron ions. The concentration of iron ions would increase, and the yellow color should be deepened. Read more exciting novels for free
The reaction phenomenon of adding aluminum sulfuric acid and soda
When a solution of a solution of The first was: <<Al3 +>+3AH^{->><Al3 +>>(Ox)_{3}>. At this time, a white deposit could be observed in the solution. If he continued to add the solution of the solution of the NaH solution, the reaction would occur. The white precipitations that were produced before would gradually disappear. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What is the equilibrium phenomenon of the reaction equation of sulfuric acid and sulfuric acid?
There was no reaction between sulfuric acid and sulfuric acid, so there was no equilibrium of the reaction equation. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reaction equation of sulfuric acid and sulfuric acid
There was no reaction between Na2SO4 and CH3COH. Because the acid was weak and the sulfuric acid was strong, the reaction of the weak against the strong usually could not happen. Therefore, there were no reaction equations and reaction phenomena, so it was impossible to provide a summary in the form of a table. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Ionic equation and phenomenon analysis of the reaction between arsenous acid and sulfuric acid
It is not dissolved in water, but can be oxided by sulfuric acid. The chemical equation for the reaction of As2O3 with HNO3 is $3As2O3 + 4HNO3 + 7H2O = 6H3AsO4 + 4NO ^, and the ion equation is $3As2O3 + 4H^+ +4NO3 ^-+7H2O = 6H3AsO4 + 4NO ^. [Phenomenon analysis: During the reaction process, there will be the formation of nitrogen dioxide gas, and bubbles can be observed.] Nitric acid has a strong oxidisation. When the element of As in As2O3 is oxided, it will rise from +3 to +5 to form arsenic acid. When the element of N in Nitric acid is reduced from +5 to +2, it will form nitrogen dioxide gas. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Reaction equation and phenomenon summary of sulfur dioxide and sulfuric acid
Sulfur dioxide ($SO2 $) and sulfuric acid ($H2SO4 $) had different reactions. If it was concentrated sulfuric acid, the reaction equation was: 2H2SO4 (concentrated)+ SO2 = 2H2O +3SO3. The phenomenon was that the pungent gas ($SO2 $) was absorbed by concentrated sulfuric acid, and a small amount of smoke might be seen during the reaction ($SO3 $might form acid mist in the air). If it was diluted sulfuric acid, it would basically not react. He could simply draw a picture with the reaction equation written on it and a small picture beside it to indicate the phenomenon of smoke production. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What is the reaction of adding sulfuric acid to a colorless solution?
Your question is a little vague. Some colorless solutions would react when they were added to nitrates, while others wouldn't. For example, the colorless solution of carbon dioxide would react with the addition of sulfuric acid to produce carbon dioxide gas. The chemical equation was Na Chi CO +2HNO = 2NaNO + Chi H O + CO Chi. However, when a colorless solution of salt was mixed with sulfuric acid, no reaction would occur. This depended on the specific composition of the solution. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The preparation of bromic ether by the reaction of alcohol, NaBr2 and concentrated sulfuric acid
In the reaction of preparing bromic ether, the first reaction was the reaction between concentrated sulfuric acid and the solution of the acid.(It can only produce bisulfuric acid, which can be referred to the reaction with NaCl2). The reaction equation is [H_{2} SO4}+ NaBr2 = NaHSO4 + Brr]. Then the formed [Brr] will react with alcohol. Under the conditions of concentrated sulfuric acid absorbing water and heating, the bromoether will be vaporized. The reaction equation is [Brr + CH3} CH2} 0H = CH3} CH2} Br2 + H2}O]. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
