Questions & Step-by-Step Solutions
Which colligative property is affected by the presence of electrolytes?
Correct Answer: Vapor pressure lowering
Step 1: Understand what colligative properties are. These are properties that depend on the number of solute particles in a solution, not their identity.
Step 2: Know that electrolytes are substances that dissociate into ions when dissolved in water.
Step 3: Realize that when electrolytes dissolve, they increase the total number of particles in the solution because one electrolyte can produce multiple ions.
Step 4: Recognize that since colligative properties depend on the number of particles, the presence of electrolytes will affect all colligative properties, such as boiling point elevation, freezing point depression, vapor pressure lowering, and osmotic pressure.
