Oxygen is more electronegative than sulphur yet H2S is acidic while H2O is neutral. This is because.
Water is highly associated compound
H-S bond is weaker than H2O is neutral.
H2S is a gas while H2O is a liquid
The molecular weight of H2S is more than that of H2O
In which reaction there is no change in the oxidation states?
SO2 + H2S → 2H2O + 3S
2Na + O → Na2O
Na2O2 + H2SO4 → Na2SO4 + H2O
4KCIO3 →3KCIO4 + KCI
