Hydrogen sulfates, also known as bisulfates, are salts or esters of sulfuric acid where one hydrogen atom has been replaced by a metal or organic group. They typically form acidic solutions when dissolved in water.

5 Must Know Facts For Your Next Test

  1. Hydrogen sulfate is commonly represented by the chemical formula $HSO_4^-$.
  2. In aqueous solutions, hydrogen sulfates can dissociate to form sulfuric acid and sulfate ions.
  3. Sodium bisulfate (NaHSO_4) is a widely used hydrogen sulfate in various industrial processes including cleaning and pH adjustment.
  4. Hydrogen sulfates are intermediates in the production of sulfuric acid through the contact process.
  5. They exhibit both acidic and ionic properties due to their ability to donate a proton (H+) and form salts.
