Reaction equation and phenomenon analysis of sulfur dioxide and acidic bichromic acid
以硫酸为例，二氧化硫与酸性重铬酸钾反应的化学方程式为：\(K_{2}Cr_{2}O_{7}+3SO_{2}+H_{2}SO_{4} = K_{2}SO_{4}+Cr_{2}(SO_{4})_{3}+H_{2}O\)，其离子方程式为：\(Cr_{2}O_{7}^{2 - }+3SO_{2}+2H^{+}=3SO_{4}^{2 - }+2Cr^{3 + }+H_{2}O\)。 在这个反应中，重铬酸钾（\(K_{2}Cr_{2}O_{7}\)）中的铬元素从 +6价被还原为 +3价的\(Cr^{3 + }\)，而二氧化硫（\(SO_{2}\)）被氧化为硫酸根离子（\(SO_{4}^{2 - }\)）。反应现象方面，溶液的颜色会发生变化，由于重铬酸根离子（\(Cr_{2}O_{7}^{2 - }\)）通常具有特定颜色（一般为橙红色），反应后生成的\(Cr^{3 + }\)离子具有不同颜色（一般为绿色），所以反应过程中可以观察到溶液颜色由橙红色转变为绿色。 <a href="/?from=ask_words" style="color:red" target="_blank">点击前往免费阅读更多精彩小说</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>
Ion equation and phenomenon summary of sulfur and metal reaction
For the reaction between sulfur and metal, the following are the common reactions and situations: - Sulfur and iron reaction: The chemical equation is: FeS + S = (heating)FeS. This reaction does not involve free moving ions, so it cannot be rewritten as an ion equation. The phenomenon was the formation of black solid iron Sulphide. - Sulfur and copper reaction: The chemical equation is 2Cu + S = (heating) Cu2 S. Similarly, the ion equation cannot be written. The phenomenon was the formation of black cuprous sulfur solid. - Sulfur and Na reaction: The chemical equation is 2Na + S =(grinding)Na <2> S. There is no need to rewrite the ion equation. The phenomenon was that during the grinding process, a violent reaction formed a white solid of sulfur dioxide. - Sulfur and aluminum reaction: The chemical equation is 3S +2AI = Al2S, which cannot be rewritten as an ion equation. The reaction phenomenon was the formation of aluminum sulfur solid. - Sulfur and mercury reaction: The chemical equation is as follows: Mercury + S = HgS, which cannot be written as an ion equation. The reaction phenomenon is the formation of black mercury sulfur solid. In general, since most of these reactions were solid-state reactions or did not carry out the ionisation process in the solution system, there was basically no ion equation. Most of the reaction phenomena were the formation of the corresponding sulfur solid, and the color of the solid was different. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What does the reaction of sulfuric acid and sulfur dioxide produce?
The reaction between diluted sulfuric acid and sulfur dioxide produces water, nitrogen dioxide gas, and sulfur precipitations. The reaction equation is: 8HNO +3Na ^S = 4H ^O + 2NO ^+6NaNO + 3S. The reaction between concentrated sulfuric acid and sulfur dioxide produces water, nitrogen dioxide gas, and sulfur precipitations. The reaction equation is: 4HNO + Na ^S = 2H ^O + 2NO ^+ 2NaNO + S. However, there was also a view that the reaction could not produce sulfur and sulfur. Instead, it would produce either sulfur and sulfur, or sulfur and water, or other nitrogen and oxygen compounds. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Reaction equation and phenomenon analysis of aluminum ion and carbon dioxide
The equation for the reaction between aluminum ions and carbonates is: 2Al3 + +3CO32- +3H2O === 2Al3 + 3CO2. The analysis of the reaction phenomenon was as follows: When aluminum ions (Al3 +) came into contact with carbon dioxide ions (CO32-), theoretically, they would form aluminum dioxide, but aluminum dioxide was a weak acid and weak base salt, and it was easy to decompose in an aquatic solution. In the process of digestion, aluminum ions combined with the hydrogen ions in the water to form aluminum trioxides. At the same time, the carbon dioxide ions came into contact with the hydrogen ions. As the carbon dioxide was unstable and volatile, it decomposed to produce carbon dioxide gas. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reaction equation phenomenon and explanation of the phenomenon of the reaction equation of the reaction of the reaction
There is no chemical reaction between NaCl2 and magnesiumcarbonate2. In chemistry, the conditions for metathesis reactions to occur were the formation of precipitations, gases, or water. After mixing the two, the conditions for the metathesis reaction were not met, so there was no reaction, no reaction equation, and no reaction phenomenon. <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?

What is the reaction of adding concentrated sulfuric acid to the solid of sulfur dioxide?
When concentrated sulfuric acid was added to the solid of the sulfur dioxide, since the concentrated sulfuric acid had a strong oxidisation property and the sulfur dioxide had a reduction property, the two would undergo an oxidoreduction reaction. The reaction equation is [Na ^S + H ^SO (concentrated)= S + Na ^SO + H ^O]. The reaction phenomenon was the formation of sulfur, and at the same time, the formation of sulfuric acid and water. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
