  2. Sulfuric acid - Wikipedia

    en.wikipedia.org/wiki/Sulfuric_acid

    Sulfuric acid (American spelling and the preferred IUPAC name) or sulphuric acid (Commonwealth spelling), known in antiquity as oil of vitriol, is a mineral acid composed of the elements sulfur, oxygen, and hydrogen, with the molecular formula H 2 SO 4. It is a colorless, odorless, and viscous liquid that is miscible with water. [7] Structure ...

  3. Sulfurous acid - Wikipedia

    en.wikipedia.org/wiki/Sulfurous_acid

    Sulfuric(IV) acid (United Kingdom spelling: sulphuric(IV) acid), also known as sulfurous (UK: sulphurous) acid and thionic acid, [citation needed] is the chemical compound with the formula H 2 SO 3. Raman spectra of solutions of sulfur dioxide in water show only signals due to the SO 2 molecule and the bisulfite ion, HSO − 3. [2]

  4. Solubility - Wikipedia

    en.wikipedia.org/wiki/Solubility

    The term solubility is also used in some fields where the solute is altered by solvolysis. For example, many metals and their oxides are said to be "soluble in hydrochloric acid", although in fact the aqueous acid irreversibly degrades the solid to give soluble products. Most ionic solids dissociate when dissolved in polar solvents.

  5. Azeotrope tables - Wikipedia

    en.wikipedia.org/wiki/Azeotrope_tables

    This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.

  6. Sulfate - Wikipedia

    en.wikipedia.org/wiki/Sulfate

    The hydrogensulfate ion (HSO − 4), also called the bisulfate ion, is the conjugate base of sulfuric acid (H 2 SO 4). [59] [b] Sulfuric acid is classified as a strong acid; in aqueous solutions it ionizes completely to form hydronium (H 3 O +) and hydrogensulfate (HSO − 4) ions.

  7. Lead(II) sulfate - Wikipedia

    en.wikipedia.org/wiki/Lead(II)_sulfate

    Lead(II) sulfate (PbSO 4) is a white solid, which appears white in microcrystalline form.It is also known as fast white, milk white, sulfuric acid lead salt or anglesite.. It is often seen in the plates/electrodes of car batteries, as it is formed when the battery is discharged (when the battery is recharged, then the lead sulfate is transformed back to metallic lead and sulfuric acid on the ...

    en.wikipedia.org/wiki/Mercury(II)_sulfate

    Solubility in water. Decomposes in water to yellow mercuric subsulfate and sulfuric acid Solubility: soluble in hot H 2 SO 4, NaCl solution insoluble in alcohol, ...

  9. Silver sulfate - Wikipedia

    en.wikipedia.org/wiki/Silver_sulfate

    Silver sulfate precipitates as a solid when an aqueous solution of silver nitrate is treated with sulfuric acid: 2 AgNO 3 + H 2 SO 4 → Ag 2 SO 4 + 2 HNO 3. It is purified by recrystallization from concentrated sulfuric acid, a step that expels traces of nitrate. [7] Silver sulfate and anhydrous sodium sulfate adopt the same structure. [8]
