Hydrogen Sulfate - HSO4-

What is Hydrogen sulfate?

Hydrogen Sulfate is an anion with the chemical formula HSO4. It forms sulfuric acid when exposed to water. HSO4 very small hydrogen sulfate ion. Sodium Bisulfate which is the pure substance NaHS04 melts at 185°C and begins to lose water with a good deal of spattering. It consists of sulfur atom in the center surrounded by four oxygen atoms form a tetrahedral arrangement. The structure is similar to the structure of methane.

Chemical Properties of Hydrogen Sulfate – HSO4

    • Hydrogen sulfate when treated with water forms hydronium ion and sulfate ion. The chemical equation is given below.

HSO4 + H2O → H3O+ + SO42-

    • Hydrogen sulfate reacts with nitrate ion forming nitrous acid and sulfate ion. The chemical equation is given below.

HSO4 + NO2 → SO42- + HNO2

Uses of Hydrogen Sulfate – HSO4

  • Used as a substitute for liquid sulfur dioxide in the removal of residual chlorine after wastewater treatment.
  • Sodium salt of hydrogen sulfate is commonly called niter cake because it was formerly obtained by the obsolete process.
  • The resin is used to soothe the skin, and its reddish juice stanches blood when used in styptic pencils.

Frequently Asked Questions

How are hydrogen sulfate and sulfuric acid different?

The HSO4- ion is commonly referred to as hydrogen sulfate (which is also called the bisulfate ion). H2SO4 can be called dihydrogen sulfate (but it is popularly known as sulfuric acid).

Is hydrogen sulfate a strong or a weak acid?

The hydrogen sulfate ion, also known as the bisulfate ion, is an acid. It can be classified as a weak acid. Part of the reason for its acidity is due to its electronegative oxygen isolating electron density away from the oxygen-bonded hydrogen atom.

What is the charge held by hydrogen sulfate molecules?

The magnitude of the net charge held by hydrogen sulfate molecules is -1. Upon gaining a proton, this compound forms sulphuric acid, whose chemical formula is H2SO4.

What is the chemical formula of hydrogen sulfate?

The chemical formula of hydrogen sulfate isHSO4–.

What is the melting point of hydrogen sulfate?

The melting point of hydrogen sulfate is 59 °C
