Give reason for the following :
(i) Chlorine water loses its colour on standing.
(ii) The is more acidic than `H_(2)S`.

Text Solution

Verified by Experts

(i) Chlorine water (light greenish in colour) onstanding changes to HCl and HClO. Both these products are colourless. `Cl_(2) +H_(2)O to HCl +HClO`
(ii) The bond dissociation enthalpy of H-Te bond is less than that of H-S bond. Therefore, `H_(2)Te` is more acidic as compared to `H_(2)S`.
