What is Na2HSO4? Important knowledge about Na2HSO4

1. Definition of Na₂HSO₄
   Sodium bisulfate, also known as Sodium hydrogen sulfate (English name: Sodium bisulfate), has the chemical formula of Na₂HSO₄. This is a salt containing sodium cations (Na) and hydrogen sulfate anions (HSO₄-). It has a relative atomic mass of 120.06 g/mol.

In the structure of Na₂HSO₄ molecule, each sodium hydrogen sulfate molecule contains two sodium atoms, one sulfur atom, four oxygen atoms, and one hydrogen atom.

1.2. Properties of Na₂HSO₄
Physical properties: Sodium hydrogen sulfate typically appears as colorless, odorless white crystals. It has a PH level of about 1, creating a strong acidic environment.
Chemical Properties: Sodium hydrogen sulfate can convert to sodium sulfate (Na₂SO₄) when heated. It can also react with metals to form salts and hydrogen.

2. Common chemical reactions involving Na₂HSO₄
   Na₂HSO₄ + 2NaOH -> 2Na₂SO₄ + 2H₂O

3. Synthesizing Na₂HSO₄
   In the laboratory, Na₂HSO₄ can be synthesized by reacting NaOH with H₂SO₄, followed by an evaporation process to collect the precipitate.
   In industry, Na₂HSO₄ is usually produced by reacting NaCl or Na₂SO₄ with H₂SO₄ at high temperatures.
