Reaction of aluminum with concentrated sulfuric acid, adding water
When aluminum comes into contact with concentrated sulfuric acid, it will undergo a passive phenomenon, which is to form a dense layer of an oxygen film on the surface of the aluminum to prevent the reaction from proceeding further. If water was added to this system, the concentrated sulfuric acid would be diluted into diluted sulfuric acid. At this time, aluminum would react with the diluted sulfuric acid. The chemical equation was 2AI +3H ^SO = AI ^(SO)^+3H ^^. Read more exciting novels for free
Reaction between aluminum phosphorous acid and concentrated sulfuric acid
The chemical equation for the reaction of aluminum phosphorous acid (AlPo) with concentrated sulfuric acid is: AlPo +3HQ = AlCl2 + H Po. The reaction phenomenon was that the solid aluminum phosphorous acid gradually dissolved. Since the aluminum chloride-formed (AlClCl2) and phosphorous acid (H3PO4) were both water-dissolved, the solid of aluminum phosphorous acid gradually decreased until it was completely dissolved as the reaction progressed. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reaction of concentrated sulfuric acid, concentrated sulfuric acid, and concentrated sulfuric acid
When the reaction of the solution of excessive amount of potassium moons and concentrated sulfuric acid was carried out, the pale yellow crystals of phosphorus moons would be formed. The reaction equation was: PO4 ^3- +12MoO4 ^2- + 3NH4^+ + 24H^+= (NH4)3(P(Mo12O40))·6H2O → +6H2O. This was the characteristic reaction for identifying phosphorus radical. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Does aluminum react with concentrated sulfuric acid and concentrated sulfuric acid? Is it poisonous?
The aluminum would react with concentrated sulfuric acid and concentrated sulfuric acid. In the early stages of the reaction, a small amount of aluminum dioxide would be formed. Later, a dense layer of aluminum dioxide would form on the surface of the aluminum, preventing the reaction from proceeding further. This phenomenon was called detoxification. Condensed sulfuric acid and concentrated sulfuric acid were corrosive and dangerous chemicals, but there was not enough information to show whether the products formed by the reaction of aluminum with them were toxic. It was impossible to accurately answer whether the reaction products were toxic. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The reaction phenomenon of adding aluminum sulfuric acid and soda
When a solution of a solution of The first was: <<Al3 +>+3AH^{->><Al3 +>>(Ox)_{3}>. At this time, a white deposit could be observed in the solution. If he continued to add the solution of the solution of the NaH solution, the reaction would occur. The white precipitations that were produced before would gradually disappear. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reaction of aluminum and sulfuric acid
The chemical equation of the reaction between aluminum and sulfuric acid is [2AI +6HQ = 2AlCl3 + 3H2]. At the beginning of the reaction, there was a layer of oxygen film on the surface of the aluminum strip, so there were fewer bubbles. As the reaction progressed, more and more heat was released, and more and more bubbles were produced. Later, the concentration of the sulfuric acid decreased, and the reaction rate decreased, so the bubble production rate slowed down, and the bubbles became fewer and fewer. Finally, the sulfuric acid was exhausted. In this reaction, aluminum showed its reducing properties. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reaction of aluminum meta-aluminum and aluminum sulfuric acid
The chemical equation of the reaction between meta-aluminum aluminum (NaAlO <2>) and aluminum (Al2 (SO2)<2> is: 6NaAlO <2>+ Al2 (SO2)<2>+12H <2> O = 8Al2 (NO3)<2>+3Na <2> SO2 <2>, and the ion equation is: Al3 <2>+3AlO2 <2>+6H <2> O = 4Al2 (NO3)<2>. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
How to match the reaction formula of concentrated sulfuric acid and concentrated sulfuric acid with the reaction formula of aromatic acid?
Under the catalyst of concentrated sulfuric acid, 1 mole of aromatic acid and 1 mole of concentrated sulfuric acid reacted to form 1 mole of nitrogen and 1 mole of water. The reaction formula was: C6H6 (aromatic ring)+ HNO3 + H2SO4 (catalyst) → C6H5-NO2 + H2O. If it was to form m-dinitro, the reaction formula was: C6H6 + 2HNO3--> C6H4 (NO2) 2 (dinitro is in the meta-position)+2H2O. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
identification method for reaction of concentrated sulfuric acid and sulfuric acid
Acetic anhydryride-concentrated sulfuric acid reaction (Liebermann-Burchard reaction) can be used to identify tripenoid and steroid side. The specific identification method was as follows: dissolve the sample in vinegar and add concentrated sulfuric acid-vinegar (1:20). If the final color was red or purple, it was triterpene soap. If the final color was blue-green, it was steroid soap. During the reaction process, color changes such as red → purple → blue → green → dirty green would occur in turn, and finally the color would fade. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Reaction of aluminum phosphorous acid and sulfuric acid? Why?
The reaction between aluminum phosphorous acid (AlPo) and sulfuric acid (HQ) occurs. This was a typical alkali-base reaction. As the salt of a weak acid (phosphorous acid), aluminum phosphorus was decomposed by sulfuric acid, which formed aluminum chloride-phosphorous acid (AlClCl2) and phosphorous acid (H PO2). The chemical equation was: AlPO2 + 3HQ → AlCl2 + H PO2. In actual experiments, reaction conditions such as concentration and temperature would affect the reaction rate and yield. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
