The conductivity of 0.02 M AgNO3 at 25°C is 2.428 × 10-3Ω-1cm-1. What is its molar conductivity?

Answer»

Given : 

Concentration of solution = C = 0.02 M AgNO3 

Temperature = T = 273 + 25 = 298 K 

Conductivity = κ = 2.428 × 10-3-1cm-1 (or S cm-1)

Molar conductivity = ∧m = ?

m\(\frac{k\times 1000}{C}\)

\(\frac{2.428\times 10^{-3}\times 1000}{0.02}\)

= 121.4 Ω-1 cm2 mol-1 

(or 121.4 S cm2 mol-1)

∴ Molar conductivity = ∧m

= 121.4 Ω-1 cm2 mol-1.

A metal is known to form fluoride `MF_(2)`. When `10` ampere electricity is passed through a molten salt for `330` sec, `1.95 g` metal is deposited. Find out the atomic weight of metal. What will be the quantity of charge required to deposit the same mass of `Cu` from `CuSO_(4)(aq.)`? (`At. wt.` of `Cu = 63.6`)A. 57.02B. 148C. 228D. 114

Answer» Correct Answer - D
i=10 amp , t = 330 sec , w = 1.95 gm , E = ?
`W = (ixxt xx E)/(96500)`
`therefore E = (W xx 96500)/(ixxt) = (1.95 xx 96500)/(10 xx 330) = 57.02`
Molten salt is `MF_(2)`
Valency of fluorine = `(-1) xx 2 = -2`
`therefore` Valency of M= + 2
`E = ("At. mass")/("valency")`
`therefore` At. mass = `E xx` valency
`= 57.02 xx 2 = 114.04 = 114`

A metal is known to form fluoride `MF_(2)`. When `10` ampere electricity is passed through a molten salt for `330` sec, `1.95 g` metal is deposited. Find out the atomic weight of metal. What will be the quantity of charge required to deposit the same mass of `Cu` from `CuSO_(4)(aq.)`? (`At. wt.` of `Cu = 63.6`)

Answer» Eq. of metal `= (i.t)/(96500)`
`(i = 10 "ampere", t = 330 sec.)`
`(1.95)/(E) = (10 xx 330 sec)/(96500)`
`E_("metal") = 57.0`
`At. wt.` of metal `= 57.0 xx 2 = 114.0`
metal is bivalent as salt is `MF_(2)`
Also, if `w_(Cu) = 1.95 g`, then
or `(1.95)/(63.6//2) = (i.t)/(96500)`
`:. i.t = Q = 5917.45` coulomb

`n_(Pd) = (2.977)/(106.4)`
`n_(Pd) = 0.028`
`n_(E) = 0.028 xx n`
`= (0.0238 xx n xx 96500)/(3600) =3 [1=(q)/(t)]`
`n = 4`

Answer» Correct Answer - a
Oxidation of `H_(2)O` to `O_(2)`
`2H_(2)Orarr4H^(+)+O_(2)+4e^(-)`
2 mol 4 mol
1 m ol 2 mol
`therefore` one mole of water release 2 moles of electrons on oxidation
1 mol of electron =96500C
2 moles of electrons =`2xx96500C`

The cost of electricity required to deposit 1 g of Mg is Rs.3.00. The cost of deposit 8 g of Al is (al.mass Al = 27 , Mg = 24)A. Rs.`12.00`B. Rs. `24.00`C. Rs. `32.00`D. Rs.`42.50`

Answer» Correct Answer - C
`(W_(Al))/(W_(Mg)) = (E_(Mg))/(E_(Al))`
`therefore (W_(Al))/(1) = (24//2)/(27//3) = (12)/(9)`
`therefore W_(Al) = (12)/(9)` gms.
When 1 gm of Mg deposited at the same time , `(12)/(9)` gm of Al deposited by passing same quantity of electricity
For 1 gm Mg `-=` it cost three rupees
`therefore (12)/(9) g Al -= x : x = (3 xx (12//9))/(1) = 4` rupees
`therefore` For 8 gm of Al `-= 8 xx 4 = 32` rupees

Explain the effect of dilution of solution on conductivity ?

Answer»
  • The conductance of a solution is due to the presence of ions in the solution. More the ions, higher is the conductance of the solution. 
  • Conductivity or the specific conductance is the conductance of unit volume (1 cm ) of the electrolytic solution. 
  • The conductivity of the electrolytic solution always decreases with the decrease in the concentration of the electrolyte or the increase in dilution of the solution. 
  • On dilution, the concentration of the solution decreases, hence the number of (current carrying) ions per unit volume decreases. Therefore the conductivity of the solution decreases, with the decrease concentration or increase in dilution. (It is to be noted here that, molar conductivity increases with dilution.)

The passage of 0.95 A current for 40 minutes deposited 0.7493 g Cu from CuSO4 solution. Calculate the molar mass of Cu.

Answer»

Given : 

Electric current = I = 0.95 A 

Time = f = 40 min = 40 × 60 = 2400 s 

Mass of Cu deposited = 0.7493 g 

Molar mass of Cu = ? 

Reduction half reaction,

\(Cu^{2+}_{(aq)}\) + 2e- ⟶Cu(s)

Quantity of electricity = Q = I × t

= 0.95 × 2400

= 2280 C

Number of moles of electrons = \(\frac{2280}{96500}\) 

= 0.02362 mol 

∵ 2 mol electrons deposit 1 mol Cu 

∴ 0.02362 mol electrons will deposit,

\(\frac{0.02362}{2}\) = 0.01181 mol Cu

Now, 

0.01181 mol Cu weighs 0.7493 g

∴ 1 mol of Cu weigh,

\(\frac{0.7493\times 1}{0.01181}\) = 63.44 g

Hence molar mass of Cu 63.44 g mol-1

∴ Molar mass of Cu = 63.44 g mol-1.
