1.	Formulate possible compounds of ‘Cl’ in its oxidation state is:0, -1, +1, +3, +5, +7 H_(2)O_(2) act as an oxidising agent as well as reducing agent where as O_(3) act as only oxidizing agent. Prove it.
Answer» Solution :(i) Cl oxidation number 0 in `Cl_(2)`. (ii) Cl oxidation number-1 in HCl. (iii) Cl oxidation number +3 in `HClO_(2)` . (iv) Cl oxidation number +5 in `KClO_(3)` . (v) Cl oxidation number +7 in `Cl_(2)O_(7)` . In `H_(2)O_(2)` oxidation number of OXYGEN is -1 and it can vary from 0 to -2 (+2 is POSSIBLE in `OF_(2)`). The oxidation number can decrease or increase, because of this `H_(2)O_(2)` can act both oxidising and REDUCING agent. Ozone `(O_(3))` only acts as oxidising agent since it decomposes to give NASCENT oxygen.
