Trioxosulphuric acid is a liquid without colour and has a pungent burning sulphur smell. The extrapolated values in water were found to be in good agreement with literature data. You'll get a detailed solution from a subject matter expert that helps you learn core concepts. This phenomenon is called the leveling effect: any species that is a stronger acid than the conjugate acid of water ($H_3O^+$) is leveled to the strength of $H_3O^+$ in aqueous solution because $H_3O^+$ is the strongest acid that can exist in equilibrium with water. For example, hydrochloric acid is a strong acid that ionizes essentially completely in dilute aqueous solution to produce $H_3O^+$ and $Cl^$; only negligible amounts of $HCl$ molecules remain undissociated.
