Question

Conductivity always decreases with decrease in concentration both, for weak and strong electrolytes because of the fact that ____________.

Options

• the number of collisions of ions per unit volume that carry the current in a solution increases on dilution

• the number of ions per unit volume that carry the current in a solution decreases on dilution

• the number of ions per unit volume that carry the current in a solution increases on dilution

• mobility of ions that carry the current in a solution increases on dilution

Answer 1

Conductivity always decreases with decrease in concentration both, for weak and strong electrolytes because of the fact that the number of ions per unit volume that carry the current in a solution decreases on dilution.

Explanation:

Conductivity is the conductance of a one-centimeter cube of the solution. so on dilution the number of ions per cm³ decreases.
