Dialysate conductivity is primarily a measure of what property?

• A. The Osmolarity
• B. The pH Level
• C. The Total Electrical Charge Of A Solution
• D. The Viscosity

Answer: (C)

Dialysate conductivity reflects how well the solution can carry an electrical current. This ability comes from the ions present in the solution—the charged particles. The more ions there are and the more mobile they are, the higher the conductivity. So conductivity mainly tracks the total ionic content and how effectively those ions move, which is why it’s about the solution’s charge carriers. Osmolarity counts all solute particles, not just charged ones, so it’s not as direct a measure of conductivity. pH relates to hydrogen ion activity, not overall conduction. Viscosity affects flow, not electrical conduction.
