# What are the symbols with oxidation numbers for sulfuric acid? What is the formula?

I can only assume what you are trying to ask in your question, but sulfur has an oxidation number of $8$, oxygen has an oxidation number of $- 2$ and hydrogen has an oxidation number of $1$.
In sulfuric acid, the molecular formula is ${\text{H"_2"SO}}_{4}$. Oxygen almost always has an oxidation number of $- 2$, so $4$ oxygen atoms means the charge is $8 -$. Sulfur, in this case, has an oxidation number of $+ 6$, which means that ${\text{SO}}_{4}$ ion has an overall charge of $2 -$. Thus we need to hydrogen atoms to balance the charges.
