Call

`[H_(2)SO_(4)]=(19.6)/(98)=0.2 M` and `KOH=(11.2)/(56)=0.2M`
so for equivalent point, `(0.2xx50xx2)/(0.2)=100mL` of `KOH`solution should be added.
`[H^(+)]=(0.2xx2-0.2)/(2)=0.1M` so `pH=1`.

`SO_(3) (g)` is produced as : `SO_(2) (g) + (1)/(2) O_(2) (g) hArr SO_(3) (g)` At `900 K, 0.2 `mol of `SO_(2)` and 0.4 mol of `O_(2)` are taken in 2L

Correct Answer - C `{:(,SO_(2) (g),+,(1)/(2)O_(2) (g),hArr,SO_(3) (g),T = 900 K,),("Concentration",(0.2)/(2),,(0.4)/(2),,,,),("initially",,,,,,,),("concentration",0.1 - x,,0.2 - (1)/(2) x,,x,,),(,x = 0.08 M,,,,,,),(,,,,,,,):}` `K_(C) = ([SO_(3)])/([SO_(2)] [O_(2)]^(1//2)) = (0.08)/(sqrt(0.16) xx 0.02) = 10`

Mixture of X=0.02 mol of `[Co(NH_(3))_(5)SO_(4)]` Br and 0.02 mol of `[Co(NH_(3))_(5)Br]SO_(4)` was prepared in 2 litre of solution. 1 litre of mixtur

Correct Answer - a Concentration of ions in 1 litre of the solution after mixing will be reduced to half i.e. 0.01 mol. `underset((0.01"mol"))(Br^(-)+AgNO_(3))tounderset((0.01"mol"))(AgBr(Y))` `underset((0.01"mol"))(SO_(4)^(2-)+BaCI_(2))tounderset((0.01"mol"))(BaSO_(4)(Z))`

A certain reactant `XO_3^(-)` is getting converted to `X_2O_7` in solution.the rate constant of this reaction is measured by titrating a volume of the

Correct Answer - 6 `XO_3^(-) to X_2O_7` a-x ax6=30`implies a=5` `(a-x)xx6+(x/2xx16)=36` `implies x=3` `k=2.303/9.212"log"(5/2)=0.1 "min"^(-1) =6 hr^(-1)`

A spherical balloon of volume 5 litre is to be filled up with `H_2` at NTP from a cylinder of 6 litre volume containing the gas at 6 atm at `0^@C`.The

Correct Answer - 6 Volume of gas at NTP is , `P_1V_1=P_2V_2` `6xx 6 =1xxV_2` `V_2`=36 litres. Outcoming gas = 36-6 =30 litres No of balloon =`30/5=6`

`50mL` of `0.05M` Propane `-1,2-`diamine solution is titrated with `0.1M HCl` solution at `25^(@)C`. Detemine the `pH` of solution obtained by adding

(a) Half neutralisation :`pH=pK_(a_(1))=14-4.18=9.82` (b)`pH=((pK_(a_(1))+pK_(a_(2)))/(2))=(14-4.18+14-7.39)/(2)=8.215` (c ) Buffer: `pH=14-7.39+log((2.5-0.5)/(0.5))=7.21`

The `pH` of a solution resulting from the addition of `12.5mL` of `0.1M HCl` to `50mL` of a solution containing 0.15M `CH_(3)COOH` & `0.2M` `CH_(3)COO

`{:(,CH_(3)COONa,+,HCl,rarr,CH_(3)COOH,+,NaCl),(t=0,10,,1.25,,7.5,,-),(t=eq,8.75,,0,,8.75,,-):}` `pH=pK_(a)=4.74`

Which of the following solutions have different `pH`? `100mL" of "0.2m" "HCl +100mL" of "0.4 M" "NH_(3)` `50mL" of "0.1 M" HCl +"50mL" of "03.2 M NH(3

(a) `{:(NH_(4)OH,+,HCl,rarr,NH_(4)Cl,+,H_(2)O),(0.2M,,0.1,,0.1,,0),(0.1,,0,,0.1,,0.1):}` `pOH=pK_(b)` (b) `{:(NH_(4)OH,+,HCl,rarr,NH_(4)Cl,+,H_(2)O),(0.1M,,0.05,,0,,0),(0.05,,0,,0.05,,):}` `pOH=pK_(b)+log(((0.05)/(0.05)))=pK_(b)` c `{:(NH_(4)OH,+,HCl,rarr,NH_(4)Cl,+,H_(2)O),(0.3,,0.15,,,,),(0.15,,0,,0.15,,):}` `pOH=pK_(b)` so all solution have same `pH`.
