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 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>
The principle of the reaction between diluted sulfuric acid and soda is
The reaction between diluted sulfuric acid and soda is a neutralizing reaction. The principle of the reaction is that the hydrogen ions (H) in sulfuric acid combine with the hydrogen ions (H) in soda to form water (H O). The chemical equation is as follows: During the reaction process, with the addition of the sulfuric acid, the Oh in the solution of sulfuric acid would continuously combine with the H. If the solution of sulfuric acid was dripped with the sulfuric acid, the red color would gradually disappear due to the decrease of the Oh. When the red color disappeared, it meant that the added sulfuric acid and the solution of sulfuric acid had completely reacted. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Reaction of iron rust and sulfuric acid
The main component of rust was iron dioxide (Fe2 O2), and there was no such exact compound as "rust monocrystal." According to the reaction between rust (Fe2 O2) and sulfuric acid (HNO2), the reaction equation is Fe2 O2 + 6HNO2 = 2Fe2 (NO2)+3H2 O. This reaction is not an oxido-reduction reaction because iron and nitrogen are in the highest valency state and cannot undergo oxido-reduction reactions. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The difference between the reaction equations of concentrated and diluted sulfuric acid
Taking the reaction of copper and sulfuric acid as an example, the reaction equation of concentrated sulfuric acid is: Cu +4HNO2 (concentrated) = Cu(NO2) 2 + 2NO2 ^+2H ^O, and the reduction product is NO2; The reaction equation of diluted sulfuric acid is: 3Cu +8HNO2 (diluted) = 3Cu(NO2) 2 + 2NO2 ^+4H ^O, and the reduction product is NO. The stronger the concentration of the acid, the stronger the ability to catalyze. This was reflected in the different reaction products. For example, the chemical equation of the reaction between concentrated sulfuric acid and carbon is: C+4HNO (concentrated) = CO2 ^+4NO2 ^+2H O; When dilute sulfuric acid and sulfur react, only S2 ions can be oxided into elemental sulfur, while when concentrated sulfuric acid and sulfur react, S2 ions can be further oxided into SO2 ions, such as 3dsS + 8HNO (diluted) = 3Cadr (NO2) 2 + 2NO2 ^+4H O + 3S. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
