What is the oxidation number of SO4? - Answers
2024年5月27日 · The oxidation number of chromium (Cr) in Cr2(SO4)3 is +3. This is because the overall charge of the sulfate ion (SO4) is -2, and there are a total of 3 sulfate ions present in the compound ...
How is (SO4)^2- Charged if S and O all are Neutral Themselves?
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.
inorganic chemistry - Why is anhydrous copper(II) sulfate white …
2017年4月5日 · On the other hand, the $\ce{[SO4]^2-}$ ions, which are weakly held in the axial positions of $\ce{CuSO4.5H2O}$, are gradually brought into the equatorial coordination sphere, so that their CT interaction with the $\ce{Cu^2+}$ ion will be strongly enhanced. The observed spectral changes thus come about.
Reaction between concentrated sulfuric acid and sodium bromide
2022年2月19日 · $\begingroup$ E.g. type $\ce{2e- +4H+ + SO4^2- -> SO2 + 2H2O}$ to get $\ce{2e- +4H+ + SO4^2- -> SO2 + 2H2O}$. That is for inline formula or equation within the text. To display it in dedicated space, use double dollars: $$\ce{2e- +4H+ + SO4^2- -> SO2 + 2H2O}$$ // Use 4 trailing spaces for forced newline, or double enter for an empty line ...
How does H2SO4 dissociate? - Chemistry Stack Exchange
2018年6月17日 · My question is, why can't the dissociation reaction happen like this: $$\ce{H2SO4 -> 2H^+ +SO4^{2-}}$$ I know hydrogen is a diatomic gas, but here I don't know if H will dissociate as a gas or as a liquid (since $\ce{H2SO4}$ is a liquid, not a gas).
What is the balanced equation for the reaction of potassium ...
2015年9月11日 · $$\ce{KMnO4 + FeSO4 + H2SO4 -> K2SO4 + MnSO4 + Fe2(SO4)3 + H2O}$$ I found out that manganese is reduced as the oxidation number goes from $+7$ to $+2$ and iron gets oxidized as the oxidation number goes from $+2$ to $+3$. I wrote the two half reactions, \eqref{Q:red} for the reduction and \eqref{Q:ox} for the oxidation. Did I get them right?
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.
Why does copper sulfate disassociate into Cu+2 and SO4-2 when …
2017年8月17日 · Basically $\ce{CuSO4}$ already exists as $\ce{Cu^{2+}}$ and $\ce{SO4^{2-}}$. It's anhydride form exists as an orthorhombic arrangement of ions. The opposite charge attraction balances the like-charge repulsions and the crystal stays bound. When you dissolve it into water, a few things happen.
inorganic chemistry - Why iron reacts differently with …
2015年10月11日 · $$\ce{2Fe^2+ + SO4^2- + 4H+ -> 2Fe^3+ + SO2 + 2H2O}$$ In the dilute acid, this equilibrium lies far to the left because the concentrations of $\ce{SO4^2-}$ and $\ce{H+}$ are rather low. However, making the acid more concentrated shifts the equilibrium to the right so that you get some of the products.
