Chemical formulae of tetraoxosulphate(4)acid
The VI part is correct but the name tetraoxosulfate(VI) acid is NOT a correct name. One of the IUPAC names is sulfuric acid. That is the most common. There are other correct names that are accepted by IUPAC but tetraoxosulfate(VI) acid is NOT one of them. In my opinion the STOCK system adopted by the IUPAC has set nomenclature back a hundred years. 30 years ago almost no one knew what the Stock system was. Now students gravitate to that system, especially when they can't remember the common name like sulfuric acid, but they don't get it right.
My question is
Is h2so4
Tetraoxosulphate (iv) acid or tetraoxosulphate (vi) acid
Which of the Roman numeral is correct cus I see both
The correct name for H2SO4 is sulfuric acid. The 4 is incorrect also in your naming scheme. The correct oxidation number for S in H2SO4 is 6+. If you are trying to name sulfurous acid, that does have S with an oxidation number of 4+ and the formula for that is H2SO3.
Tetraoxosulphate(vi)acid
The chemical formula for tetraoxosulphate(4) acid is H2SO4.
To derive the formula, you should first understand the valence or combining capacity of each element. In the case of sulphur (S), it has a valence of 6, meaning it can form six bonds with other atoms. Oxygen (O) has a valence of 2, meaning it can form two bonds. Hydrogen (H) has a valence of 1, so it can form only one bond.
Now, let's break down the name "tetraoxosulphate(4) acid" to identify the number and types of atoms present in the compound:
- "Tetra" indicates that there are four oxygen atoms present.
- "Oxo" refers to the presence of oxygen in the compound.
- "Sulphate" indicates that we have a sulphur atom and the compound is a derivative of the sulfate ion (SO4^2-, where the total charge of the ion is -2).
To balance the charges in the compound, we need two hydrogen atoms. Therefore, we can determine that the chemical formula for tetraoxosulphate(4) acid is H2SO4.
It is important to note that the prefix "tetra-" indicates the number of oxygen atoms, while the valencies of the elements help determine the overall formula.
