# Hydrogen Sulfate Formula

## Chemical Formula of Hydrogen Sulphate

Hydrogen sulfate, also called bisulfate, is a salt of sulfuric acid and an ion with the chemical formula HSO$_{4}^{-}$. The chemical compounds with this ion are called bi-sulfates or hydrogen sulfates. They are acidic in nature and may be used as a weaker form of acid compared to sulfuric acid. The formula of the hydrogen sulfate indicates that it holds one atom of hydrogen and sulfur, each with four oxygen atoms. And the ion carries a ‘–1” charge.

Sulfate is given as the salt of sulphuric acid. A sulfate ion is the group of atoms that have the formula it means., SO$_{4}$ and 2 negative charges. Furthermore, it consists of a central sulfur atom, which is surrounded by 4 equivalent oxygen atoms.

### Hydrogen Sulfate Formula and Structure

Hydrogen sulfate chemical compound has the molecular formula (HSO$_{4}^{-}$), an image representing its chemical structure is given below in the common representations that we normally use for the organic molecules:

The chemical structure of hydrogen sulfate can be represented as follows:

### Uses

The chemical compound hydrogen sulfate contains different types of uses based on the situation and the need also, where some of them are as follows:

We can use hydrogen sulfate as a substitute for the liquid sulfur dioxide in the removal process of the residual chlorine after conducting the wastewater treatment. Furthermore, the sodium salt of the hydrogen sulfate is commonly called the niter cake because previously, it was obtained by the obsolete process. In addition, the resin can be useful for soothing the skin of human beings, and its reddish type juice will stanch the blood when we use the hydrogen sulfate in the styptic pencils.

1. How are Hydrogen Sulfate and Sulfuric Acid Different?

Answer: Sulfuric acid is a very strong acid that ionizes completely to form hydronium ions (H3O+) and hydrogen sulfate ions (HSO4-) in an aqueous solution.

In dilute solutions, the hydrogen sulfate ions (HSO4- ion)  which is also commonly called the bisulfate ion,  dissociates to forme more hydronium ions and sulfate ions (SO42-).

2. Explain if Hydrogen Sulfate is a Strong or a Weak Acid?

Answer: The hydrogen sulfate ion, which is also referred to as the bi-sulfate ion, is defined as an acid. It may be classified as a weak acid. Part of the reason for its acidity is because of its electronegative oxygen isolating electron density away from oxygen-bonded hydrogen atoms.

3. Give the Name of HSO4- Acid?

Answer: Sulfate ions need something with an oxidation number of ‘+2’ to make it a complete molecule. This ion is chemically formulated as HSO4-.

And, the acid is referred to as ‘sulfuric acid.’ This compound (HSO4-) is also known as either ‘hydrogen sulfate ion’ or ‘bi-sulfate ion.’ Usually, the bi-sulfates are acid salts, which are created when sulphuric acid meets a metallic base.

The chemical reaction is given as follows:

Sulphuric acid + Metal base →  Metal Bisulfate + Water/Acid

4. What kind of Compound is KHSO4?

Answer: Potassium hydrogen sulfate (with the chemical formula KHSO4), also called potassium hydrogen sulfuric acid, belongs to the inorganic compound class called alkali metal sulfates. These are the inorganic compounds, where the largest oxoanion is sulfate, whereas the heaviest atom not in an oxoanion is an alkali metal.

5. What Type of Salt is NaHSO4?

Answer: In terms of composition, sodium hydrogen sulfate (NaHSO4) is given as an ‘acid salt’ as it contains single replaceable hydrogen. When this specific intermediate salt is treated with more sodium hydroxide (with complete neutralization), it results in sodium sulphate (Na2SO4), which is sodium hydroxide and the ‘normal salt’ of sulphuric acid.
