Hydrogen sulphide is acidic while water is neutral. The reason is (RPMT 2010)
A.molecular weight of H2S is more than H2O
B.water molecules associate, while H2S molecules
C.H-S bond is weaker than H-O bond due to the✓ Correct
D.S- atoms has less affinity for hydrogen atom than
Explanation
Acidic nature of a molecule is based on the extent of ejection of H ions in the aqueous state. Hydrogen sulphide is acidic while water is neutral because the H- S bond is weaker than the O-H bond due to the bigger size of the sulphur atom. And intermolecular hydrogen bonding in water is another reason for the neutrality of water.
