Hydrogen Sulfate Formula

Hydrogen Sulfate Formula

The Hydrogen Sulfate Formula, also known as the Bisulfate Formula, is a sulfuric acid salt. Furthermore, it is an ion with the chemical formula HSO4-. Furthermore, chemical compounds containing this ion are known as hydrogen sulfates or bisulfates.

On the other hand, these are acidic and can be used as a weaker form of acid than sulfuric acid. The formula for hydrogen sulfate shows that it is made up of 1 atom of hydrogen and 1 atom of sulfur, each of which has 4 atoms of oxygen. The ion, on the other hand, has a charge of -1.

Hydrogen Sulfate Properties

The hydrogen Sulfate Formula has a density of 2.345 g/cm3 and a melting point of approximately 58.5 °C. The hydrogen sulfate molar mass is 97.0715 g/mol. When we add hydrogen Sulfate Formula to water, it dissolves quickly.

 Furthermore, it has no odour because it is odourless by nature and has the appearance of a white powder. It has a Covalently Bonded Unit, which is 1. 

Hydrogen Sulfate Chemical Structure

The molecular formula of the chemical compound Hydrogen Sulfate Formula is (HSO4–). It appears as a white powder with no odour; it is odourless. Sulfuric acid, a salt with a molar mass of 97.0715 g/mol, contains hydrogen sulfate.


The hydrogen Sulfate Formula has a molar mass of 97.0715 g/mol. It has a density of 2.345 g/cm3. It can easily be soluble in water. The pH value of hydrogen sulfate is 1.

Chemical Properties

When the Hydrogen Sulfate Formula reacts with distilled water, it forms sulfate and hydronium ions. It can also combine with nitrate ions to form sulfate ions and nitrous acids. Hydrating sulfate can also react with water as a base to form hydronium ions.

An acid-base reaction occurs when one proton is transferred from one ion or molecule to another, according to the Brasted-Lowry equation. Water acts as a base because it reacts with HSO4, a better proton donor. This is due to water’s amphoteric nature. It can function as both a base and an acid.


According to the circumstance and the requirement, the chemical compound Hydrogen Sulfate Formula has a variety of uses, some of which are as follows:

 When removing the remaining chlorine after treating the wastewater, we can replace it with liquid sulfur dioxide. Furthermore, the sodium salt of hydrogen sulfate is commonly referred to as “niter cake” because it was previously obtained through an obsolete process. Additionally, the resin is helpful for soothing human skin, and when used in styptic pencils, its reddish-colored juice stops bleeding.

Some of the most common applications for Hydrogen Sulfate Formula. It is primarily used in water treatment plants to remove residual chlorine. One of the main alternatives to liquid sulfur dioxide is hydrogen sulfate. The sodium salts of hydrogen sulfate are used to produce niter cake. Hydrogen sulfate resins are commonly used to soothe the skin.
