• # question_answer ${{H}_{2}}S$ is more acidic than ${{H}_{2}}O$ because A)  $O-H$ bond is stronger than $S-H$ bond B)  $O$ is more electronegative than sulphur C)  $H-S$ bond is weaker than $O-H$ bond D)  $O-H$ bond is weaker than $H-S$ bond

H-S bond is weaker than 0-H bond because S-atom is bigger in size and less electronegative than 0-atom. Due to these reason ${{H}_{2}}S$ is more acidic than ${{H}_{2}}O$.
