Determine the theoretical van 't Hoff factor for each of the three solutes used in Experiment FPD. State them and explain how each was determined. Compare the theoretical values to the experimental values you calculated for your Presentation of Data submission above for each salt. How are they similar, how are they different? Would you expect the van 't Hoff factor for KCl and NaCl to be the same?

Percent ionization for a weak acid (ha) is determined by the following formula: percent ionization=[ha] ionized[ha] initialΓ100%for strong acids, ionization is nearly complete (100%) at most concentrations. however, for weak acids, the percent ionization changes significantly with concentration. the more diluted the acid is, the greater percent ionization. a certain weak acid, ha, has a ka value of 9.4Γ10? 7.part acalculate the percent ionization of ha in a 0.10 m solution. part bcalculate the percent ionization of ha in a 0.010 m solution
