The ion equation of the reaction is: [SO2]+ Br2 + 2H2 O = 4H^{+}+ SO4 ^{2 -}+2Br2}. The experimental phenomenon was that the color of the solution faded. This was because sulfur dioxide had a reducing property, while Bromine had an oxidisating property. The two would undergo an oxidoreduction reaction, causing the color of Bromine water to fade.

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>
The hydrogen ions (H) do not react with carbon dioxide (CO2). When carbon dioxide is dissolved in water, it will form carbolic acid (H Chi CO). Carbonic acid is a weak dibasic acid, and its equation is H Chi CO H + HCO, HCOH + CO2. It can produce hydrogen ions, so it will not react with hydrogen ions. If it can react with hydrogen ions, then its equation will not work. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The reaction ion equation was: Cr2O72- +3SO2 + 2H + = 3SO42- +2Cr3 + + H2O. There was no reference to this reaction, so it was impossible to give an accurate answer. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The reaction equation between nitrogen dioxide and sulfur dioxide is: <anno data-annotation-id ="c3d-a100 - 4c00 - 4c50-a150 - 9c3333c3333"></anno></anno> Phenomenon analysis: From the reaction equation, it can be seen that nitrogen dioxide is a brownish-red gas. After the reaction, it will produce nitrogen dioxide, which is a colorless gas. Therefore, the color of the brownish-red gas will gradually fade until it disappears. At the same time, the sulfur dioxide generated was a colorless gas. Under certain conditions (such as water), there would be further reactions. For example, sulfur dioxide would react with water to form sulfuric acid, which might cause acid mist and other phenomena. However, from the perspective of the reaction between the two, it was mainly a change in the color of the gas. In addition, this reaction was a complex gaseous reaction that occurred at a high temperature. It mostly occurred in a specific environment with a heated climate. The existence of a large number of reaction products could cause air pollution and affect atmospheric visibility. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
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>
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>
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>
