5. Data below (also in Brightspace) indicate freezing point depression (compared to pure water) for dilute aque- ous solutions of either NaCl or MgSO4. Use Debye-Hckel theory to estimate the fugacity and concentration dependence of each electrolyte pair. Compare these results with the freezing point depression data.
