What is NaSO4? Important knowledge about NaSO4

  1. Definition of NaSO4
    NaSO4, also known as sodium sulfate, is a chemical compound consisting of the elements sodium (Na), sulfur (S), and oxygen (O). It is formed from 2 sodium atoms, 1 sulfur atom, and 4 oxygen atoms. Its molar mass is 142.04 grams/mol. In chemistry, it is often represented as sodium ions (Na+) and sulfate ions (SO4 2-).

  2. Properties: NaSO4
    2.1 Physical properties of NaSO4: NaSO4 is a solid, colorless and odorless substance. It has a neutral pH and dissolves well in water.
    2.2 Chemical properties of NaSO4: NaSO4 does not react with water but can react with strong acids such as HCl to form H2SO4 and NaCl.

  3. Common chemical equations involving NaSO4
    NaSO4 often reacts with alkali metals such as K, Na to form other salts. For example, NaSO4 + 2K -> K2SO4 + 2Na.

  4. Preparation of NaSO4
    4.1 Laboratory preparation of NaSO4: NaSO4 is usually prepared by reacting NaOH with H2SO4. The reaction equation is: 2NaOH + H2SO4 -> Na2SO4 + 2H2O.
    4.2 Industrial preparation of NaSO4: In industry, NaSO4 is often produced from the treatment process of wastewater containing sodium and sulfate.
