$\overline{){{\mathbf{\Delta T}}}_{{\mathbf{f}}}{\mathbf{=}}{{\mathbf{imK}}}_{{\mathbf{f}}}}$

i = 1 → non-electrolyte or compounds that do not ionize

i = # of ions produce → electrolytes or compounds that 100% ionize

###### Problem Details

For an aqueous solution of HF, determine the van't Hoff factor assuming...

0% ionization                                     100% ionization

A solution is made by dissolving 0.0300 mol of HF in 1.00 kg of water. The solution was found to freeze at -0.0644 °C. Calculate the value of i and estimate the percent ionization of HF in this solution.

so HF is

a) 0% ionized

b) between 0% and 50% ionized

c) 50% ionized

d) between 50% and 100% ionized

e) 100% ionized

in this solution.
