May 27, 2024 · 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 ...

Oct 14, 2015 · 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.

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.

Jun 22, 2024 · Lead has two oxidation states (+4 and +2). As a result, there are two compounds composed of lead and sulfate: lead(IV) sulfate, which is Pb(SO4)2, and lead(II) sulfate, which is PbSO4.

Jun 11, 2024 · What is the chemical name of S04? The name of SO4 is called sulfate. But it has a charge of negative 2. There are many compounds with sulfate in them such as H2SO4 which is sulfuric acid, Na2SOR ...

May 24, 2024 · To find the grams in 2.4 moles of SO4, you need to multiply the number of moles by the molar mass of SO4 (sulfate). The molar mass of SO4 is 96.06 g/mol. Therefore, 2.4 moles of SO4 would be 2.4 ...

Jun 17, 2024 · SO4 is an ionic compound. It is known as sulfate, which consists of a sulfate anion (SO4^2-) and cations, usually metal ions, to balance the charge.

Sep 5, 2015 · $$\ce{HSO4- (aq) + H2O <-> H3O+ (aq) + SO4^2- (aq)}$$ The sulfate ion should be a weak conjugate base, and hence the sodium sulfate salt should be a weak base. This was my line of reasoning, until today my friends told me it is actually a neutral salt, which was confirmed by searching online.

Jun 19, 2024 · No, though the SO4- portion of H2SO4 is. In ionic compounds, the cation (positive ion) will be listed first, in this case, H2. The anion (negative ion) is next, in this case SO4 (a polyatomic ion)

Sulf ate $\ce{SO4^2-}$ You can see that 'ate' has one more oxygen, and that I have listed them in charge order. Sometimes looking at the trends in oxygen and charge will help you memorize. I have had to remember them by writing them down several times and now I am comfortable. Here is another example: Hypochlorite is $\ce{ClO^-}$ So, chlorite ...
