The reaction between hydrogen sulfurous acid and sulfurous acid produced elemental sulfur and water. The reaction did not produce gas. The reaction equation is: H <2> SO2 <2>+2H <2> S = 3S <2>+3H <2> O. Read more exciting novels for free
When concentrated sulfuric acid reacted with metals, such as iron and concentrated sulfuric acid, a small amount of hydrogen sulphide would be formed under heating. The reaction equation was: 4Fe+5H SO===== 4FeSO+ H S ^+4H O; The reaction of sulfuric acid with polysulfuric acid would produce hydrogen sulphide. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
When the reaction between the two was carried out, the reaction equation was: Mn + H ^SO2 = Mn ^SO2 + H ^. The reaction between the two was to produce hydrogen and sulfuric acid. When the reaction between the two was carried out, the reaction equation was: Mn +2H ^SO2 (concentrated)= Delta = Mn ^SO2 + Mn ^SO2 + 2H ^O2, which was a reduction reaction. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The chemical equation for the reaction of hydrogen dioxide and dilute sulfuric acid is: 2HNO2 + 3H ^S = 2NO ^+4H ^O + 3S ^. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The reaction between copper dioxide and diluted sulfuric acid produced copper dioxide and water. The reaction equation was CuO + H2SO4 = CuSO4 + H2O. No gas was produced during this reaction, and no gas was produced when heated. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
If it was concentrated sulfuric acid, it would release heat when dissolved in water. However, hydrogen dioxide was unstable and decomposed to produce oxygen when heated, but the two would not directly react. Dilute sulfuric acid did not react with hydrogen peroxid. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Iron and sulfuric acid react to form iron sulfuric acid (FeSO2) and hydrogen gas (H <2>) instead of iron sulfuric acid. The reaction equation is: Fe2 + H2 SO2 → Fe2 SO2 + H2. During the reaction, the iron surface was corroded by hydrogen ions (H) in sulfuric acid, forming hydrogen gas (H) and iron ions (Fe2). The iron ions combined with the sulfuric acid ions (SO2) to form FeSO2. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
When the copper sulfuric acid solution reacted with diluted sulfuric acid, it would form copper ions such as copper chloride2. In the solution, copper ions (Cu2) and Cl2 (Cl2) combine to form copper ions. During the reaction process, there are also various ion forms such as copper ions. Moreover, with the different amount and concentration of Cl-ions, the color of the solution would change due to the combined influence of the yellow copper ions and the blue copper ions. For example, the solution might turn green. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The reaction between the sulfuric acid and the soda ash would produce a large number of bubbles. The soda ash powder would dissolve rapidly, and the gas produced would turn the clear lime water turbid, indicating that the gas produced was carbon dioxide. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Copper and diluted sulfuric acid did not react, so copper sulfuric acid and hydrogen would not be formed. Because the activity of copper was after hydrogen, diluted sulfuric acid reflected the oxidisation of hydrogen ions. Its oxidisation was weak, and it could only catalyze the prohydrogen metals in the metal activity order table. Therefore, copper could not replace the hydrogen in diluted sulfuric acid. However, copper can react with concentrated sulfuric acid to form copper sulfuric acid, water, and sulfur dioxide under heating. The reaction equation is: Cu+2H ^SO2 (concentrated)= CuSO2 + 2H ^O + SO2 ^; In the presence of oxygen, copper can also react with diluted sulfuric acid to form copper sulfuric acid and water. The reaction equation is: 2Cu+ O2 + 2H ^SO2 = 2CuSO2 + 2H ^O. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
1. Reaction of carbonates and sulfuric acid: - The reaction principle was: <<CO3 ^{2 -}+2H ^+>> to H2O + CO2> - Reaction phenomenon: When adding sulfuric acid to a solution containing carbonates (such as a solution of Na2CO3), bubbles will be produced. This was because the reaction produced carbon dioxide gas. 2. Reaction of hydrogen radical and sulfuric acid: - The reaction principle was as follows: <<p>(Ox ^ -+H^+<p> to H2O>). - Reaction phenomenon: If the reaction of the hydrogen radical in an alkali-based solution such as soda ash with sulfuric acid, there would be no obvious visual phenomenon (such as no color change, precipitations, or gas generation, etc.), but the temperature of the solution would increase because the alkali-base neutralizing reaction was an exhalation reaction. If one touched the outer wall of the reaction container, one could feel the heat. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
