Question

Dilution affects both conductivity as well as molar conductivity. Effect of dilution on both is as follows:

Options

• both increase with dilution.

• both decrease with dilution.

• conductivity increases whereas molar conductivity decreases on dilution.

• conductivity decreases whereas molar conductivity increases on dilution.

Answer 1

Conductivity decreases whereas molar conductivity increases on dilution.

Explanation:

The concentration of ions in a solution determines its conductivity. With dilution, this reduces. Dilution enhances molar conductivity by increasing the dissociation of the weak electrolyte, resulting in more active ions in the solution.
