Dissociation of solute particles leads to a / an ____ in the magnitude of a colligative property and a / an ____ in the value of the observed molecular mass.
Answer
Answer
AIBlanks: increase; decrease
increase; decrease. Dissociation increases the total number of solute particles ($i > 1$), which increases colligative properties. Because molar mass is inversely proportional to colligative properties, the observed molecular mass decreases.
