The reaction between the solid of sulfur dioxide and concentrated sulfuric acid is Na2S +2H2SO4 (concentrated) == S +2H2O + SO2 + Na2SO4. Read more exciting novels for free
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>
Elemental sulfur can undergo an oxido-reduction reaction with concentrated sulfuric acid under heating conditions. Sulfur is oxided to sulfuric acid with a +6 valency, and concentrated sulfuric acid is reduced to nitrogen dioxide with a +4 valency. The reaction equation is: S +6HNO= heating = H ^SO+ 6NO ^+2H ^O. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
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>
The reaction equation for the reaction between ethene and concentrated sulfuric acid was: CH2 = CH2 + H2SO4 → CH3CH2OSO3H. In chemistry, there was no reaction without heating or concentration, such as the reaction between carbon and concentrated sulfuric acid or concentrated sulfuric acid, the reaction between copper and concentrated sulfuric acid. The reaction between ethene and concentrated sulfuric acid was not mentioned. However, according to the laws of chemistry, ethene had a certain degree of reduction, and concentrated sulfuric acid had strong oxidization. Under certain conditions, the two could react. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Sulfur can react with a strong oxiding acid. For example, sulfur can react with concentrated sulfuric acid: S +2H <2> SO2 <2>(concentrated)= 3SO2 <2>+2H <2> O(under heating). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The reaction between the alcoholic group and the solution was an alkali-base reaction, which was accompanied by the protonation of the alcoholic group and the deprotonation of the solution. In the reaction, the hydrogen atom in the alcoholic group was replaced by the alcoholic group in the sulfuric acid, forming water and a positively charged ion. At the same time, the negative ion in the sulfuric acid combined with the positively charged ion in the alcoholic group to form a salt. The reaction equation was: <<p>><p></p>><p></p>><p><p>><p><p>><p><p>><p><p>><<p>><p> p>><p>> p> p>>& gt In general, because the alcoholic group was weakly acidic, it could react with the strong base, namely, soda. It did not require any special reaction conditions and could react at any time. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
At room temperature, concentrated sulfuric acid would have a slow corrosive effect on the polythene, and at 90 - 100 ° C, concentrated sulfuric acid would rapidly erode the polythene, causing it to be destroyed or decomposed. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
过氧化钠与硫酸反应实际分两步进行,第一步反应为\(2Na_{2}O_{2}+2H_{2}O = 4NaOH + O_{2}\),第二步反应为\(2NaOH+H_{2}SO_{4}=Na_{2}SO_{4}+2H_{2}O\),总的反应方程式为\(2Na_{2}O_{2}+H_{2}SO_{4}=Na_{2}SO_{4}+2NaOH + O_{2}\)。 <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>
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>
