Which statement correctly explains why H2S is a stronger acid than water?(1 point)

Responses

Sulfur (S) has a larger atomic size than oxygen (O), so H2S is a more stable, weaker base than H2O.
Sulfur (S) has a larger atomic size than oxygen (O), so H 2 S is a more stable, weaker base than H 2 O.

The correct statement is:

Sulfur (S) has a larger atomic size than oxygen (O), so HS⁻ is a more stable, stronger acid than OH⁻.

This is because the larger atomic size of sulfur relative to oxygen means that the H–S bond is weaker than the H–O bond. Therefore, it is easier for H₂S to donate a proton (H⁺) compared to water, making H₂S a stronger acid. Additionally, the anion HS⁻ is more stable than OH⁻, contributing to the stronger acidic character of H₂S compared to water.
