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-). -
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. -
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. -
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.
