The term "bisulfate" is also commonly used to refer to sodium hydrogen sulfate. This alternative name is derived from the fact that the compound contains two hydrogen atoms per sulfate group. This distinction becomes important in chemical reactions involving the exchange of protons.

Understanding the chemical name of sodium hydrogen sulfate is essential for effectively working with the compound in laboratory or industrial settings. The name provides a concise description of its elemental composition and structural characteristics, facilitating its identification and proper handling.

Molecular Weight of Sodium Hydrogen Sulfate: Unveiling Its Chemical Identity

In the realm of chemistry, understanding the molecular weight of a substance is crucial in deciphering its composition and properties. For sodium hydrogen sulfate, this value plays a pivotal role in revealing its chemical identity and characteristics.

Calculating the Molecular Weight:

The molecular weight of a compound is the sum of the atomic weights of all its constituent atoms. In the case of sodium hydrogen sulfate, its formula is NaHSO₄, which suggests that each molecule contains one sodium atom (Na), one hydrogen atom (H), one sulfur atom (S), and four oxygen atoms (O).

Using the periodic table, we can find the atomic weights of these elements:
- Na: 22.99 g/mol
- H: 1.01 g/mol
- S: 32.07 g/mol
- O: 16.00 g/mol

Step-by-Step Molecular Weight Calculation:

  1. Multiply the atomic weight of each element by its number of atoms in the molecule:
    • Na: 22.99 g/mol x 1 = 22.99 g/mol
    • H: 1.01 g/mol x 1 = 1.01 g/mol
    • S: 32.07 g/mol x 1 = 32.07 g/mol
    • O: 16.00 g/mol x 4 = 64.00 g/mol
  2. Sum up the results:
    • 22.99 g/mol + 1.01 g/mol + 32.07 g/mol + 64.00 g/mol = 120.07 g/mol

Therefore, the molecular weight of sodium hydrogen sulfate is 120.07 g/mol.

Physical State of Sodium Hydrogen Sulfate

Sodium hydrogen sulfate, a solid at room temperature, is a white crystalline substance with a monoclinic structure. The crystalline structure refers to the orderly arrangement of its molecules within a crystal lattice. In the case of sodium hydrogen sulfate, the individual molecules are arranged in a repeating pattern within the crystal, resulting in a solid with a well-defined shape.
