A substance that appears dark spots after a thermal reaction with diluted sulfuric acid.
If the substance contains carbon, etc., dark spots may appear after the thermal reaction with diluted sulfuric acid. For example, pig iron contained carbon. After adding enough diluted sulfuric acid to react fully, the iron completely reacted to form a dissolved FeSO4, while carbon did not react with diluted sulfuric acid, so there would be a small amount of black material (mainly carbon) left in the beaker. However, based on the available information, it was impossible to accurately point out all the substances that appeared dark spots after the thermal reaction with diluted sulfuric acid. There might be other substances that would appear similar phenomena under specific reaction conditions. Read more exciting novels for free
What substance can be formed by the reaction of diluted sulfuric acid and iron?
The reaction between diluted sulfuric acid and iron will produce iron dioxide and hydrogen. The chemical reaction equation is: Iron (iron)+ H ^SO2 (diluted sulfuric acid)= FeSO2 (iron dioxide)+ H ^(hydrogen). This was because diluted sulfuric acid was weak in its oxidisation. It could not be oxided to iron ions (+3Fe), but could only be oxided to iron ions (+2Fe). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reaction equation of sulfuric acid and diluted sulfuric acid
The chemical equation for the reaction between sulfuric acid and sulfuric acid is: 2H ^SO2 + Na ^SO2-> 2NaHSO2 + Na ^SO2 + H ^O. In this reaction, the phenomenon was summarized as follows: - The reaction was an exothermic reaction that would produce heat. - Due to the production of sulfur dioxide gas, there may be a pungent smell (if it can be observed under suitable experimental conditions). It should be noted that sulfuric acid and sulfuric acid are dangerous chemicals, and safety should be paid attention to when operating or observing related reactions. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reaction of Na with diluted sulfuric acid and sulfuric acid
The reaction between the dilute sulfuric acid and the sulfuric acid was very intense. The chemical properties of Na were very active. When it was placed in diluted sulfuric acid, Na would first react with water to form Na_2 and H_2. The chemical equation was 2Na +2H_2 O = 2Na_2 Sulfur and H_2. The resulting Na_2 would then react with diluted sulfuric acid. The chemical equation was 2Na_2 Sulfur and H_2 Sulfur = Na_2 Sulfur and 2H_2 O. When the solution was added to the acid, it would react with water to form hydrogen and hydrogen. At the same time, the hydrogen would react with the acid immediately. The chemical equation was 2Na +2HQ = 2NaCl2 + H ^. In short, the reaction between the two acids and the sulfur would produce hydrogen. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Reaction of P-nitrotoluene and diluted sulfuric acid? Why?
P-nitrotoluene and diluted sulfuric acid can react. P-nitrotoluene was a kind of alcoholic compound, which was slightly acidic. When it reacted with diluted sulfuric acid, it would undergo an acidic reaction. According to the process of preparing p-nitrotoluene, the reaction between the salt of p-nitrotoluene (sodium-phenate) and diluted sulfuric acid would change the reaction liquid's pH. When the reaction liquid reached a certain pH-value (such as 2 - 3), the reaction would stop. This process was the process of converting p-nitrotoluene into p-nitrotoluene. The reverse process was the reaction of p-nitrotoluene with base to produce p-nitrotoluene. Therefore, it could be inferred that p-nitoluene could react with diluted sulfuric acid. The essence of the reaction was an alkali-base neutralizing reaction. P-nitrotoluene provided a electron, and the sulfuric acid ions in the diluted sulfuric acid combined with the electron. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
