Transcribed Image Text:For an aqueous solution of HF, determine the van't Hoff factor assuming 0% ionization.
i =
For the same solution, determine the van't Hoff factor assuming 100% ionization.
i =
A solution is made by dissolving 0.0200 mol HF in 1.00 kg of water. The solution was found to freeze at -0.0443 °C. Calculate
the value of i and estimate the percent ionization of HF in this solution. Kf for water is 1.86 °C/m.
i =
Expert Solution
Step 1
- For zero percent ionisation of HF, i = 1 as only HF will be left in the solution.
Now when complete ionisation of HF takes place HF will dissociates into H+ and F- in that case vant hoff factor will become equal to no. of disccaited species i.e 2.
