Question

Suggest a way to determine the molar conductivity of water

Answer 1

Limiting Molar conductivity is the molar conductivity at infinite dilution and it is calculated as:

∧ =∧ - K√C

Where, ∧ = limiting molar conductivity, ∧ = molar conductivity , K =empirical constant and c = electrolytic concentration of solute.

So, ∧ =∧ + K√C

Also, limiting molar conductivity is calculated as:

∧ = (no. of moles of cation x limiting molar conductivity of cation) + (no. of moles of anion x limiting molar

conductivity of anion)

Value, of limiting molar conductivity of water depends on the ion of the dissolved electrolyte.

Answer 2

Answer:

Explanation:

We know that water is a weak electrolyte. Its molar conductivity at infinite dilution i.e., Λ°m can be determined in terms of Λ°m, for strong electrolytes.  This is in accordance with Kohlrausch's law.
