Question

How can the conductivity of a salt solution be decreased?

A. Add more salt to increase the concentration.
B. Add more water to decrease the concentration.
C. Add more water to increase the concentration.
D. Add more salt to decrease the concentration.

Answer 1

B. Add more water to decrease the concentration.

Step-by-step explanation:

If we add more water to the solution, the concentration is decreased and like wise the conductivity of the solution.

• Concentration is the amount of solute in a solution.
• Conductivity deals with the ability of a solution to allow the passage of current.

Concentration and conductivity are directly proportional to one another. The higher the concentration, the higher the conductivity and vice versa.

• Adding more water increases the amount of solvent and the concentration reduces.
