Question

For an electrolytic solution of 0.05 mol per litre the conductivity is found to be 0.022 ohm the molar conductivity is

Answer 1

Given: Electrolytic solution of 0.05 mol per litre the conductivity is found to be 0.022 ohm .

To find: The molar conductivity ?

Solution:

• Now we have given an electrolytic solution of 0.05 mol per litre the conductivity is found to be 0.022 ohm.

• So M is 0.05 M and k is 0.022 ohm

• Formula for molar conductivity is:

                 ∧(m) = k x 1000 / M

• So putting the values in formula, we get:

                 ∧(m) = 0.022 x 1000 / 0.05

                 ∧(m) = 22 / 0.05

                 ∧(m) = 2200 / 5

                 ∧(m) = 440 ohm / M

Answer:

            So the molar conductivity is 440 ohm / M
