No, sulphurous acid is not stronger than sulphuric acid. In fact, sulphuric acid is a much stronger acid than sulphurous acid. This is because sulphuric acid is a diprotic acid, meaning that it can donate two protons (H+ ions), while sulphurous acid is a monoprotic acid, meaning that it can only donate one proton. This means that sulphuric acid can release more H+ ions into solution, which makes it more acidic.

The strength of an acid is determined by its ability to donate protons. The more protons an acid can donate, the stronger it is. Sulphuric acid is a stronger acid than sulphurous acid because it can donate two protons, while sulphurous acid can only donate one.
