    Hydrogen sulfate also commonly known as bisulfate is an anion. The hydrogen sulphate formula is given by HSO sulfate is formed with the chemical radical sulfate (HSO 4).When HSO 4 are exposed to water, they react to form Sulfuric Acid (H 2 SO 4).With the Sulfate radial, hydrogen sulfates are generally acidic in nature.

    In the case of sulfate or sulfite we do not need to make double bonds, but another example in which a double bond would be necessary is C 2 H 4. In this example, several rules come in to play: the most symmetrical structure is best and hydrogen cannot be bound to more than one atom (form 1 bond). Knowing these rules makes it easier to determine that the two carbons must be bound to each other ...

  • How do you write hydrogen sulfide? –

     · Hydrogen sulfide is a chemical compound with the chemical formula H2S. This means it is made of two hydrogen atoms, and one sulfide. Is H2S an acid or base? H2S is a weak acid. H2S is a Brønsted acid, because it is donating a proton to the water. It is also a Lewis acid, because it is accepting a pair of electrons to form the OH bond in hydronium ion. H2S has two lone pairs on the S, so it ...
