The hydrogen peroxid could react with the iron sulphate. In terms of the nature of the reaction, the hydrogen peroxide-containing metal was oxidiser, and the iron ions in the metal were oxidiser. The two would undergo an oxidoreduction reaction. The reaction equation is 2FeSO + H ^O ^+ H ^SO = Fe2 (SO)+2H ^O (when considering the sulfuric acid in the solution of iron sulfuric acid); from an ion point of view, it is the reaction of iron ions and hydrogen peroxid to form iron ions and water.

At the beginning of the reaction, only a small amount of bubbles were produced. After a while, a large number of bubbles were produced. Finally, a reddish-brown deposit appeared at the bottom of the test tube. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The hydrogen dioxide could not reduce the sulfuric acid, and the two did not react. This was because, from a chemical point of view, hydrogen dioxide had both oxidisation and reduction properties. In this system, it did not have the ability to reduce sulfuric acid. The two did not have the chemical driving force for the reaction, so there would be no reaction. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The reaction between the solution of potassium iodate and the solution of hydrogen peroxideneeded to be carried out under acidic conditions, so sulfuric acid was added to the reaction. The reaction equation was H2O2 + 2Ki + H2SO4 = I2 + K2SO4 + 2H2O. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
硫酸铜可以与多种物质发生反应,以下是一些可能产生较剧烈反应的情况: 1. **与活泼金属反应**:硫酸铜溶液与活泼金属(如铝)反应时,在特定条件下反应较为剧烈。例如当有氯离子存在破坏铝表面氧化膜时,反应会加速进行,铝将铜离子置换出来,化学方程式为\(2Al + 3CuSO_{4}=Al_{2}(SO_{4})_{3}+ 3Cu\)。 2. **与强还原剂反应**:如硫酸铜与碘化钾反应,反应方程式为\(2CuSO_{4}+4KI = 2CuI+I_{2}+2K_{2}SO_{4}\),这个反应有碘单质生成,在反应过程中可能表现出较为明显的现象,也可视为比较剧烈的反应。 不过反应的剧烈程度还受反应物浓度、反应温度、是否有催化剂等多种因素影响。例如在制备氢氧化铜沉淀时,若氢氧化钠浓度过大(≥4mol/L),生成的\(Cu(OH)_{2}\)会继续溶解,反应也会比较剧烈,反应方程式为\(Cu(OH)_{2}+2NaOH = Na_{2}[Cu(OH)_{4}]\)。 <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>
There were different views on the reaction of hydrogen and alcohol. One view was that the reaction between alcohol (CH3CH20H) and hydrogen peroxid (H2O2) could produce esh (CH3Cho2) and water (2H2O), that is, CH3CH20H + H2O2 = CH3Cho2 + 2H2O. The other view was that there would be no change after mixing the two, and there would be no chemical reaction, especially when the hydrogen peroxid was medical grade. If the hydrogen peroxid was 100% concentrated, it would explode directly. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
There was no reaction between the hydrogen peroxid and the acid. It has a pungent smell, which can cause coughing, eye pain, skin irritation and other symptoms. High concentration of hydrogen dioxide can cause symptoms such as breathlessness, difficulty in breathing, rapid heartbeat, etc. Eating or inhaling hydrogen dioxide by mistake can cause serious damage to the human body. In addition, hydrogen dioxide was a strong oxidiser that was highly corrosive and could cause damage to the skin, eyes, and respiratory tract. In particular, high concentration of hydrogen dioxide could cause chemical burns on the skin, lungs, and digestive system. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The mixture of hydrogen peroxide-hydrogen peroxide-acid and hydrogen iodinate-acid would result in an oxido-reduction reaction. The reaction equation is [H2O2 + 2Hi]. In this reaction, the valency of the oxygen element in the hydrogen peroxid decreased from-1 to-2, showing its oxidisation, while the valency of the iodine-element in the hydrogen iodinate increased from-1 to 0, showing its reduction. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
When the reaction of the iodate with diluted sulfuric acid and hydrogen peroxol occurred, an oxidoreduction reaction would occur. In this reaction system, the hydrogen peroxid had an oxidiser property, and the iodines in the potassium iodate had a reducing property. During the reaction process, there would be the formation of elemental sulfur. The chemical equation of the reaction is: H ^O ^+ 2Ki + H ^SO= I ^+ K ^SO+ 2H ^O. In terms of reaction phenomena, the color of the solution would change. Due to the color of the elemental sulfur in the water solution, the solution would turn brownish-yellow. This change process was a chemical change. Because new substances such as iodines were formed, the valency of the elements changed during the reaction process, which was in line with the characteristics of chemical changes. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
When copper sulfuric acid was heated to 110 ° C, it would lose the crystal water of the quartet. 102 ° C did not reach 110 ° C. There was no data indicating that copper sulfuric acid would have a special reaction at 102 ° C. According to its stability, there might not be any obvious reaction at 102 ° C. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
