It's name is persulfuric acid.
HSO5, also known as hydrogen sulfite ion, has a linear molecular structure with the sulfur atom in the center bonded to one hydrogen atom and four oxygen atoms. The hydrogen is at one end of the molecule and the oxygen atoms are arranged around the sulfur atom.
The Lewis structure of HSO5- shows sulfur in the center with one hydrogen atom, four oxygen atoms, and one negative charge. The sulfur atom forms bonds with each oxygen atom, and there are lone pairs of electrons on the oxygen atoms. This structure represents covalent bonds between sulfur and oxygen atoms, with the negative charge indicating an extra electron in the molecule.
