Reaction equation of aluminum and hydrogen and oxygen
When there was a small amount of oh-ions, the chemical equation of the reaction between aluminum ions and oh ions was: Al3 ++3OH - =Al(OH)3; when there was an excess of oh-ions, the chemical equation of the reaction between aluminum ions and oh ions was: Al3 ++4OH - = AlO2-+2H2O. When a small amount of oh-ions gradually becomes excessive, the chemical equation of the reaction between aluminum ions and oh ions is: AI (OH)3+OH - = AlO2-+2H2O. The ion equation for the reaction of aluminum with water is: 20H- +2Al+2H2O→ 2AlO2-+3H2. Read more exciting novels for free

The aluminum reacted to form a hydrogen solution
The solution that reacted with aluminum to produce hydrogen was an acidic or strongly basic solution. There were large amounts of hydrogen ions in acidic solutions, and large amounts of hydrogen ions in strongly basic solutions. For example, the reaction of aluminum with sulfuric acid can produce aluminum chlorideand hydrogen gas, and the reaction of aluminum with a solution of soda ash can produce aluminum metaaluminum and hydrogen gas. When considering the co-existence of ions in the solution, some ion combinations in the solution that reacted with aluminum to form hydrogen could not coexist in large quantities. For example, under acidic conditions, iron ions and nitrates would undergo an oxidoreduction reaction, and iron ions would react with hydrogen ions, so solutions containing iron ions and nitrates could not react with aluminum to produce hydrogen. The combination of the two types of ions could not coexist in large quantities in a solution that reacted with aluminum to form hydrogen. For example, Al3 +, Mag2 +, SO42-, and Na+ did not react with each other and did not react with hydrogen ions. They could coexist in large quantities in acidic solutions. <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>
The order of addition of aluminum, lithium, and hydrogen is usually as follows:
The operation of the reduction reaction of lithium aluminum hydrogen was similar to the Grignard reaction. It required dry and water-free conditions. The equipment generally consisted of a magnetic stirring device, a dropping funnel, and a three-mouth bottle with a return flow cooler (using a drying tube made of CaCl2 or N2 to isolate the humid air). Under the cooling of an ice bath, the lithium aluminum Hydride was first added, and then, the absolute ether or CHF was slowly added through the dropping funnel, and the mixture was stirred for a few minutes. Then, the reagent dissolved in the absolute ether (or TH) was added drop by drop to the ether (or TH) solution of lithium aluminum hydrogen (excess). It was also possible to first add the solution of the lithium aluminum hydrogen into the flask, and then slowly add the lithium aluminum hydrogen in portions. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Reaction between bichromate and hydrogen chloride?
Dichromate has a strong oxidisation, and the-1-valency of the Cl-in-Cl-can be reduced. The two can react, for example, the reaction of K2Cr2O7 with concentrated HQ: K2Cr2O7 + 14HQ (concentrated)= 2KC1 + 2CrCl3 + 6Cl2 ^+7H2O. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
