What is the reaction between elemental aluminum and base?
The aluminum strip was placed in a strong base solution (such as a solution of NaOx or KhOx) and heated slightly, and gas would be released. This was because the surface of the aluminum strip and the aluminum reacted with the strong base. The reaction equation was [Al2O3 + 2NaO3 = 2NaAlO2 + H2O],[2AI +2NaO3 + 2H2O = 2NaAlO2 + 3H2O](The reaction between aluminum and potassium hydrogen is the same). The essence of the reaction between aluminum and base was that aluminum first reacted with water, and the aluminum trioxides formed by the reaction were dissolved in the strong base solution, so that the reaction proceeded to the right, which was the reaction between aluminum and the strong base solution. The reducing agent was aluminum, and the oxidiser was water. Read more exciting novels for free
Anhydrous aluminum chloride-acid or base reaction
According to Lewis 'theory of acid and base, any molecules, ions, or groups that can accept an electron pair are called acid, and any molecules, ions, or groups that can donate an electron pair are called bases. Anhydrous aluminum chloridecould be used as a Lewis acid catalyst, so it was an acid reaction, not a base reaction. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

What is the principle of the reaction between the elemental halo and the concentrated base?
The principle of the reaction between the elemental halo and the concentrated base could be seen as the elemental halo reacting with water first, and the resulting product (acid) reacting with the base. For example, the reaction of Cl2, Br2, and I2 with alkalium could be regarded as reacting with water to form the corresponding hydrogen halic acid and hypohalic acid, and then these acid reacted with alkalium to form a haiide, hypohalic acid salt, and water. When F <2> reacted with alkalium, 2F <2>+2NaF + OF <2>+ H <2> O, and F <2> reacted with water to form sulfuric acid and oxygen, which then reacted with alkalium. However, I <2> reacted with an alkali-based solution at room temperature to form iodate, which was a special case. Cl2 <2> and Br2 <2> reacted with an alkali-based solution at room temperature to form hypohalite. Only when heated and reacted with a concentrated alkali-based solution could the hypohalite be formed. F <2> could not obtain "fluorite" at any temperature with an alkali-based solution. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reaction of aluminum and iron
The reaction between aluminum and iron dioxide (thermit reaction) experiment was as follows: ** 1. Experimental Materials ** Materials such as aluminum powder, iron dioxide, aluminum strip, alcohol lamp, paper funnel, iron frame, etc. were required. ** 2. Experimental Steps ** 1. A small amount of dried iron dioxide and an appropriate amount of aluminum powder were evenly mixed and placed in a paper funnel. A small amount of potassium peranate solid was added to the mixture, and a piece of magnetite strip that had been polished with sandpaper was inserted in the middle (the polishing was to remove the oxide-film on the surface of the magnetite strip for ignition). 2. He ignited the magnum strip. ** 3. Experimental Phenomenon ** 1. It immediately reacted violently. 2. It gave off a dazzling light and produced a large amount of smoke. 3. The paper funnel was burnt. 4. Some red-hot liquid beads fell onto the fine sand in the evaporating dish. After the liquid beads cooled down, they turned into a black solid. ** 4. The chemical reaction equation ** Fe2 O2 + 2Al2 = high temperature = Al2 O2 + 2Fe2. This reaction was a replacement reaction and a reduction reaction. There was no catalyst involved in the reaction. ** 5. Points to note ** 1. The paper funnel inside the glass funnel should be thicker and moistened with water to prevent damage to the funnel. 2. The evaporating dish should be lined with a suitable amount of fine sand to prevent the evaporating dish from exploding and to prevent the molten liquid from splashing out and hurting people. 3. The experimental equipment should not be too close to people to prevent them from getting injured. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

What is the reaction of the aluminum thermal reaction? Is it an exhalation reaction?
Aluminiothermic reaction was a kind of oxide-reduction reaction between aluminum and metal or non-metal compounds at high temperatures. Aluminiothermic reaction was an exhaling reaction, and its heat release was very large, usually enough to heat the product above the melting point, and the reaction could generally occur locally and be self-sustaining. This characteristic also reflected the energy-saving characteristics of the reaction. <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>
