# How does dimerization of the solute affect the freezing point depression?

It would REDUCE the observed $\text{freezing point depression......}$
$\text{Freezing point depression......}$ is a so-called $\text{colligative property}$; it depends on the NUMBER of species in solution. Should a solute dimerize, then the observed $\text{freezing point depression}$ will be half that of the hypothetical monomer. Capisce?
