True or False: H2S is a stronger acid than H2O

This statement is True.

Hydrogen sulfide (H2S) is considered a stronger acid than water (H2O) based on its ability to donate protons (H+) in aqueous solutions. In general, the strength of an acid is determined by its ionization in water. H2S can release protons to form HS and S2-, whereas water is a very weak acid, producing only a negligible amount of hydronium ions (H3O+) upon self-ionization.

The pKa value of H2S is around 7, indicating that it is more likely to donate a proton compared to water, which has a pKa of about 15.7. Therefore, H2S can be classified as a weak acid but is nonetheless stronger than water, confirming that H2S is indeed a stronger acid than H2O.
