  • What is the chemical name of SO4? - Answers
    The chemical name of SO4 is sulfate Sulfate is a polyatomic ion with a charge of -2, consisting of one sulfur atom bonded to four oxygen atoms It is commonly found in compounds such as sodium
  • What is the oxidation number of SO4? - Answers
    Since the SO4-2 ions have two negative charges and oxygen atoms in almost all compounds have two negative charges each, the sulfur atoms have an oxidation number of -2 -4 (-2) = +6
  • How is (SO4)^2- Charged if S and O all are Neutral Themselves?
    There are partial charges on the S and the O in SO4 [2-], the Sulfate ion Sulfate ions are found in sulfuric acid = H2SO4, which ionizes into SO4 [2-] + 2 H+ Oxygen is electro-negative It has a partial negative charge Think of water = H2O, which can break down into H+ and OH- With oxygen pulling the electrons toward itself, the sulfur gets a partial positive charge Sulfur can have either
  • Why (SO4)^2- does not create 4 double bonds - Chemistry Stack Exchange
    Why, in $\ce {SO4^2-}$ don't the 4 oxygens create double bonds In that case the all the oxygens will have 0 formal charge while the sulfur will have -2 In what I've seen only 2 oxygens create double bonds making the sulfur have no formal charge, 2 oxygens have -1 formal charge and 2 others no formal charge
  • Why does sulfate have this structure? - Chemistry Stack Exchange
    The S-O bond length in $\ce {SO4^ {2-}}$ is 149 pm, which is shorter than that observed in sulfuric acid (157 pm) and very close to the gas-phase bond length of sulfur monoxide which is 148 pm So, at the end of the day, an electron dot structure is a type of model that describes bonding
  • What is the formal charge of the sulfate ion (SO42-) and how . . . - Answers
    The formal charge of the sulfate ion (SO42-) is -2 This means that the sulfate ion has an overall negative charge of -2 due to the distribution of electrons within the ion's structure
  • What does SO4 stand for on the periodic table? - Answers
    'SO4' does NOT appear on the Periodic Table 'SO4^ (2-)' is the sulphate anion It has a charge of '-2' The elements that form the sulphate anion, viz sulphur (S) and oxygen (O) do appear on the
  • How do you calculate valency of sulphate? - Answers
    The valency of sulfate (SO4) is calculated by considering the individual valencies of the atoms that make up the ion In sulfate, the sulfur atom has a valency of +6, and each oxygen atom has a
  • Why does a sulphate ion have the structure SO4? - Answers
    Sulphate ion (SO4^2-) contains one more oxygen atom compared to the sulphite ion (SO3^2-) Sulphate is the fully oxidized form of sulfur, while sulphite is the partially oxidized form
  • Is SO4 an ionic compound - Answers
    Yes, Bi2 (SO4)3 is an ionic compound Bismuth (Bi) is a metal and sulfate (SO4) is a polyatomic ion that is negatively charged, so when they combine, they form an ionic compound through
