What is Na2AlO2? Important knowledge about Na2AlO2.

  1. Definition of Na2AlO2
    Na2AlO2 is the chemical formula of sodium aluminate, a white crystalline solid. It is commonly known as Sodium Aluminate. The structure of the Na2AlO2 molecule consists of two sodium atoms (Na), one aluminum atom (Al), and two oxygen atoms (O). The molecular weight of Na2AlO2 is 82.01 g/mol. The ionic structure of Na2AlO2 includes two sodium ions Na+ and one aluminate ion AlO2-.

  2. Properties of Na2AlO2
    Na2AlO2 is a white, odorless crystalline solid with a neutral or slightly alkaline pH in solution. In contact with air, it can absorb moisture and is easily hydrolyzed. Its chemical properties include the ability to react with acids to form aluminate and water.

  3. Common Chemical Reactions of Na2AlO2
    Na2AlO2 can undergo thermochemical reactions with metals such as Cu, Pb, Zn to form salts and aluminum. It can also react with acids to produce aluminate and water. However, because Na2AlO2 is a sparingly soluble solid, it is rarely involved in reactions with acids or salts.

  4. Preparation of Na2AlO2
    Na2AlO2 is usually prepared in the laboratory from sodium hydroxide and aluminum. Industrially, it is produced by heating a mixture of bauxite (Al2O3.2H2O), soda (Na2CO3), and lime (CaO) in a rotary kiln at a temperature of about 1200 degrees Celsius.
