1.	A sample of a mixture of `CaCl_(2)` and NaCl weighing 4.44 gm was treated to precipatate all the Ca as `CaCo_(3)` , which was then heated and quantitatively converted to 1.24 g of CaO. Choose the correct statements. (Atomic weight :Ca=40=23, Cl =35.5)A. Mixture contains `50% NaCI`B. Mixture contains `60% CaCI_(2)`C. Mass of `CaCI_(2)` is 2.22gD. Mass of `CaCI_(2) 1.11g`
Answer» Correct Answer - A::C `CaCl_(2) rarr CaCO_(3) rarr CaO (1.12)/(56) = 0.02` mole `CaO` `:.` Moles of `CaCl_(2) = 0.02` mole Mass of `CaCl_(2) = 0.02 xx 111 = 2.22g` `:. %` of `CaCl_(2) = (2.22)/(4.44) xx 100 = 50%`

Silver metal in ore is dissolved by potassium cyanide solution in the presence of air by the reaction `4 Ag + 8KCN +O_(2)+2H_(2)O rarr 4K[Ag(CN)_(2)]+4KOH`A. The amount of KCN required to dissolve 100g of pure Ag is 120gB. The amount of oxygen used in this process is `0.742g`C. The mount of oxygen used in this process is `7.40g`D. The volume of oxygen used at STP is `5.20` lit.
1 g of a sample of NaOH was dissolved in 50 " mL of " 0.33 M alkaline solution of `KMnO_(4)` and refluxed till all the cyanide was converted into `OCN^(ɵ)`. The reaction mixture was cooled and its 5 mL portion was acidified by adding `H_(2)SO_(4)` in excess and then titrated to end point against 19.0 " mL of " 0.1 M `FeSO_(4)` solution. The percentage purity of NaCN sample isA. `55.95%`B. `65.95%`C. `75.95%`D. `85.95%`
A sample containing `0.496 gm` of `(NH_(4))_(2) C_(2)O_(4) (MW = 124)` and inert material was dissolved in water and made strongly alkaline with KOH which converts `NH_(4)^(+)` into `NH_(3)`. The liberated `NH_(3)` was distilled into exactly 50ml of `0.05M H_(2)SO_(4)`. The excess `H_(2)SO_(4)` was back titrated with 10ml of `0.1MNaOH`. The percentage of `(NH_(4))_(2) C_(2)O_(4)` with sample isA. `40%`B. `50%`C. `60%`D. `75%`
1.575 g of oxalic acid `(CO OH)_(2).xH_(2)O` are dissolved in water and the volume made up to 250 mL. On titration 16.68 mL of this soltuion requires 25 mL of `(N)/(15)NaOH` solution for complete neutralisation. Calculate x.
`A^(n+1)` is maximum oxidised by acidified `KMnO_(4)` solution into `AO_(3)^(-)`. If `2.68` m moles of `A^(+(n+1))` requires `32.16 mL` of a `0.05M` acidified `KMnO_(4)` solution for complete oxidation,value of n is
X litres of carbon monoxide is present at S.T.P. It is completely oxidised to `CO_(2)`. The volume of `CO_(2)` formed is 11.207 L at S.T.P. What is the value of X in litres?A. `22.414`B. `11.207`C. `5.6035`D. `44.828`
Certain " mol of "HCN is oxidised completely by 25 " mL of " `KMnO_(4)`. The products are `CO_(2)` and `NO_(3)^(ɵ)` ion. When all `CO_(2)` is passed through lime water , 1 g of `CaCO_(3)` is obtained the molarity of the `KMnO_(4)` used isA. `1.44M`B. `0.72M`C. `0.36M`D. `0.8M`
Direct titration of `I_(2)` with a reducing agent is called iodimetry. If `I_(2)` is leberated by the oxidation of `I_(ɵ)` ion by a strong oxidising agent in neutral or acidic medium, the liberated `I_(2)` is then titrated with reducing agent. Iodometry is used to estimate the strngth of the oxidising agent. For example, in the estimation of `Cu^(2+)` with `S_(2)O_(3)^(2-)` `Cu^(2+)+I^(ɵ)toCuI_(2)+I_(2)` (iodometry) `I_(2)+S_(2)O_(3)^(2-)toS_(4)O_(6)^(2-)+I^(ɵ)` (iodimetry) Strach is used as an indicator at the end point, which forms bluecoloured complex with `I_(3)^(ɵ)` Disappearance of blue colourindicates the end point whe free `I_(2)` in not present. Q. In the reaction `2CuSO_(4)+4KItoCu_(2)I_(2)+2K_(2)SO_(4)+I_(2)` The equivalent weight of `CuSO_(4)` is `(Mw=159.5g mol^(-1))`A. `10%`B. `20%`C. `5%`D. `30%`
`KMnO_(4)` is a strong oxidising agent in acidic medium. To provide acidic medium `H_(2)SO_(4)` is used instead of HCl. This is becauseA. `H_(2)SO_(4)` is a stronger acid than HClB. `HCl` is oxidised by `KMnO_(4)` to `Cl_(2)`C. `H_(2)SO_(4)` is a dibasic acidD. rate is faster in the presence of `H_(2)SO_(4)`
The vapour density of a tribasic acid is x. the equivalent mass of that acid isA. `(x)/(3)`B. `x-3`C. `(2x)/(3)`D. `2x -3`
