`1` litre solution of unknown molarity is titrated by taking its `50 m

1.	`1` litre solution of unknown molarity is titrated by taking its `50 mL` solution against `KI` solution is strong acidic medium of excess `HCl`. The equivalence point was detected when `10 mL` of `0.1 M KI` was consumed The molarity of `KIO_(3)` solution is:A. `4xx10^(-4)M`B. `2xx10^(-2)M`C. `4xx10^(-3)M`D. `2xx10^(-3)M`
Answer» Correct Answer - C Meq.of `KIO_(3)="Meq.of" KI` `{:(2I^(5+)+,10e,rarr,I_(2)^(0),),(,2I^(-),rarr,I_(2)^(0)+,2e):}` `Mxx5xx50=10xx0.1xx1 rArrM=4.0xx10^(-3)`

`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.
