1.	Which of the following act both as an oxidising as well as reducing agent ?A. `H_(3)PO_(4)`B. `HNO_(3)`C. `HNO_(2)`D. `SO_(3)`
Answer» Correct Answer - C O.N. of P in `H_(3)PO_(4)=+5` (Highest) O.N. of N is `HNO_(3)=+5` (Highest) O.N of N in `HNO_(2)=+3` O.N of N in `HNO_(2)=+3` O.N of N is `SO_(3)=+6` (Highest) As O.N of nitrogen in `HNO_(2)` is +3, it means increase or decrease its O.N. Thus `HNO_(2)` acts both as an oxidisingom as well as reducing agent.

`0.80 g` of sample of impure potassium dichromate was dissolved in water and made up to `500 mL` solution. `25 mL` of this solution treated with excess of `KI` in acidic medium and `I_(2)` liberated required `24 mL` of a sodium thiosulphate solution. `30 mL` of this sodium thiosulphate solution required `15 mL` of `N//20` solution of pure potassium dichromate. What was the percentage of `K_(2)Cr_(2)O_(7)` in given sample?A. `73.5%`B. `75.3%`C. `36.75%`D. none of these
`12. g` of an impure sample of arsenious oxide was dissolved in water containing `7.5 g` of sodium bicarbonate and the resulting solution was diluted to `250 mL`. `25 mL` of this solution was completely oxidised by `22.4 mL` of a solution of iodine. `25 mL` of this iodine solution reacted with same volume of a solution containing `24.8 g` of sodium thiosulphate `(Na_(2)S_(2)O_(3).5H_(2)O)` in one litre.
