For an aqueous solution of HF , determine the van't Hoff factor assuming 0 % and 100 % ionization, respectively. A solution is made by dissolving 0.0250 mol HF in enough water to make 1.00 L of solution. At 27 °C, the osmotic pressure of the solution is 0.720 atm. What is the percent ionization of this acid?
