Question

Al - Al 2O3 - Al Cl3 - Al (OH)3 - Na3AlO3​

Answer 1

Ответ:

4Al+3O²=2Al²O³

Al²O³+ 6HCl= 2AlCl³+ 3H²O

AlCl³+3NaOH= Al(OH)³+ 3NaCl

Al(OH)³+ 3NaOH= Na³AlO³+ 3H²O

Answer 2

The series you provided represents a sequence of compounds involving aluminum (Al) and oxygen (O) atoms. Here's a breakdown of each compound:

1. Al: This refers to pure aluminum, which is a metallic element commonly used in various industries due to its low density, corrosion resistance, and excellent conductivity.

2. Al2O3: This compound is called aluminum oxide, also known as alumina. It is a ceramic material widely used in the production of refractory bricks, abrasive powders, and as a catalyst support. Alumina is also the primary component of bauxite ore, the main source of aluminum metal.

3. AlCl3: This compound is aluminum chloride, which is formed by the reaction between aluminum and chlorine. Aluminum chloride is a versatile compound used as a catalyst in various chemical reactions, such as Friedel-Crafts acylation and polymerization processes.

4. Al(OH)3: This compound is aluminum hydroxide, a white, gelatinous substance. It is commonly used as an antacid to treat symptoms of heartburn and indigestion. Aluminum hydroxide is also an important component in the production of aluminum-based chemicals and as a flame retardant in certain materials.

5. Na3AlO3: This compound is sodium aluminate, which is formed by reacting sodium hydroxide (NaOH) with aluminum hydroxide (Al(OH)3). Sodium aluminate finds applications as a flux in the production of glass, in wastewater treatment, and in the textile industry as a dyeing assistant.

Overall, these compounds showcase various uses and applications of aluminum and its compounds in different industries and chemical processes.
