Hydrogen is one of the main components of water. The hydrogen atom, as symbol H, is the first element in the periodic table. Hydrogen reacts with oxygen to form water. It has an atomic mass of 1.007825 g.mol-1 and atomic number 1. It is formed with one unit of positive charge and one electron of a nucleus. Sulfate, also Sulphate, is an ion, a salt of sulfuric acid with a molar mass of 96.06 g/mol. Sulfate is soluble in water, divalent anion produced by the oxidation of elemental sulfur and organic sulfur. The empirical formula of sulfate is SO42-.

Hydrogen Sulfate Formula

The chemical formula of Hydrogen sulfate is HSO4. The formula shows one atom of hydrogen and one atom of sulfur, along with four atoms of oxygen. Hydrogen sulfate, also known as bisulfate, is an ion. Generally, these are acidic in nature and used as a weak acid than sulfuric acid. It appears as a white color powder and doesn’t have any odor, odorless in nature. Hydrogen sulfate is a part of sulfuric acid, a salt that has a molar mass of 97.0715 g/mol. It is a major replacement for sulfur dioxide. HSO4 is the chemical formula of hydrogen sulfate.

Structure of Hydrogen Sulfate


Physical Properties of Hydrogen Sulfate

  • Hydrogen sulfate 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.
  • It appears as a white color powder and
  • It is odorless in nature.
  • It has a complexity level of 76.
  • 58.5°C is the melting point of hydrogen sulfate.

Chemical Properties of Hydrogen Sulfate

when we treat hydrogen sulfate with the water, it produces the hydronium ion and sulfate ion:

HSO4 + H2O → H3O+ + SO42-

It forms both nitrous acid and sulfate ion at the same time when it reacts with the nitrate ion. The chemical reaction is as follows,

HSO4 + NO2 → SO42- + HNO2

Uses of Hydrogen Sulfate

  • It is used in wastewater treatment in the process to remove chlorine residue.
  • It replaces the liquid sulfur dioxide.
  • The resin formed is used for soothing the skin.

Sample Questions

Question 1: Is sulfuric acid used in everyday life?


It is generally utilized in the manufacture of chemicals, e.g., in producing HCl, nitric acid, sulfate salts, engineered cleansers, colors, and medications. It is utilized in oil refining to clean pollution out of fuel and other refinery products.

Question 2: What does hydrogen sulfide do to the body?


Hydrogen sulfide (H2S) is a vapid gas with areas of strength for spoiled eggs. Openness to hydrogen sulfide might make bothering the eyes and respiratory framework. It can likewise cause unconsciousness, wooziness, migraine, shortcoming, crabbiness, sleep deprivation, and stomach upset.

Question 3: What is the principal issue in involving hydrogen as fuel?


The principal issue in involving hydrogen as a fuel for vehicles is capable of hydrogen. Hydrogen is hard to store since it spills without any problem. Additionally, it is very perilous as fuel because of its low start temperature and high burning energy.

Question 4: What does battery acid consists of?


Lead-corrosive batteries comprise two lead plates isolated by a synthetic arrangement for the most part made of 30 to 50 percent sulfuric acid, i.e., battery acid. When completely energized, the battery’s negative plate is decidedly lead, the electrolyte is concentrated sulfuric acid, and the positive plate comprises lead dioxide.

Question 5: Does hydrogen sulfide smells?


Hydrogen sulfide is a boring, combustible gas that scents like spoiled eggs at low fixation levels in the air. It is generally known as sewer gas, smells clammy, and compost gas. At high fixation levels, it has a nauseating sweet scent.

Question 6: What acid is called the King of chemicals?


Concentrated sulfuric acid is called King of Acids since it is solid corrosive, and exceptionally destructive. It is more responsive than different acids.

Question 7: Is hydrogen gas harmful?


At extremely high fixations in air, hydrogen is a basic asphyxiant gas due to its capacity to displace oxygen and cause hypoxia (ACGIH 1991). Hydrogen has no other known poisonous action.
