Choose the appropriate word(s) from the bracket [first, alc. AgCN, primary, decrease, third, increase, zero, Lucas, alc. KCN, KOH, no change, two, Tollen’s, AgOH, tertiary]:
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.

Blanks: 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.
