Question

H2s is more acidic than h2o​

Answer 1

Answer:

S is much larger atom than O, so the H–S bond is much longer and weaker than H–O; hence H2O is weaker acid than H2S. HF is stronger than H2S because the small F- ion bonds more strongly to the water molecules than does the larger HS- ion

Explanation:

Answer 2

Answer:

O-H bond is stronger than S-H bond. Also, O is more electronegative than S. Due to this, bond dissociation enthalpy of H-S bond is lower than that of H-O bond. Therefore, H2S is more acidic than H2O.
