Question

1M solution of monobasic acid HX has molar conductivity x S cm^2 mol^-1. While molar conductivity of H+ and X- at infinite dilution is 300 s cm^2mol^-1 and 100 S cm^2 mol^-1. The 1M HX solution contains 0.15 M H+. If this 1M is filled in a conducting cell if cell constant 0.1 cm^-1, the conductance is found to be Y ohm^-1. Find the value of 10Y​

Answer 1

Answer:

Let nuclear conductance of A,B,C and K be,

∧

A

,∧

B

,∧

C

and ∧

X

respectively.

Then, ∧

A

B

=140⟶(1)

∧

C

+∧

A

=120⟶(2)

∧

B

X

=198⟶(3)

(2)−(1)+(3), we get, ∧

C

+∧

X

=178.

∴ Molar conductance at infinite dilution of CX is 178.
