2024年5月27日 · The oxidation number of oxygen (O) in SO4 (sulfate) is -2. Since there are four oxygen atoms in the sulfate ion (SO4), they collectively contribute -8 to the overall charge of the ion, which is -2.

2025年2月7日 · 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 ...

2015年10月14日 · At this point calculating formal charge of those two coordinate bonded oxygen gives total formal charge of −2 and the formal charge on $\ce S$ and the double bonded $\ce O$ is zero. Thus the minus 2 charge on $\ce{SO4^2-}$ can be shown but initially all the atoms were neutral. While making bonds electrons were shared only.

2024年6月1日 · The oxidation number of the entire sulfate ion (SO4^2-) is -2. This means that the sum of the oxidation numbers of sulfur and the four oxygen atoms in the sulfate ion must equal -2.

2024年6月11日 · SO4 is the chemical formula for the anion sulfate. What is the formula name for Aluminum sulfate? Aluminum sulfate is formulated by Al2(SO4)3. What is the name for SO43?

2019年3月20日 · This leaves behind the sulfate ion: $$\ce{H2SO4 -> 2H+ + SO4^2-}$$ When the $\ce{H^+}$ ion departs, it leaves its electron behind, so it has to go somewhere (it remains with the $\ce{O}$ atom). Hypothetically if $\ce{SO4}$ existed, with all $\ce{O}$ atoms double-bonded to the $\ce{S}$ , then the sulfur would have a total of 16 electrons in its ...

2024年6月10日 · A sulfate ion has the structure SO4 because sulfur forms four bonds with oxygen atoms due to having six valence electrons. This arrangement allows each oxygen atom to share one electron with ...

2013年4月27日 · I found a site with this formula if you will, Formal Charge = [Number of valence electrons on atom] – [non-bonded electrons + number of bonds] I don't think I am using it correctly in finding the

2024年5月27日 · Yes, H2SO4 and SO4-2 are a conjugate acid-base pair. In this pair, H2SO4 is the acid that donates a hydrogen ion (H+) to become its conjugate base, SO4-2, which is the resulting species after ...

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.
