Chapter 12, Problem 105RQ

Consider an aqueous 1.00 m solution of ${\text{Na}}_{\text{3}}{\text{PO}}_{\text{4}}\text{, a}$ compound with useful detergent properties.

Calculate the (boiling point of the solution on the assumption that it does not ionize at all in solution.

Do the same calculation, assuming that the van't Hoff factor for ${\text{Na}}_{\text{3}}{\text{PO}}_{\text{4}}$ reflects 100% dissociation into its ions.

The 1.00 m solution boils at $\text{100}\text{.183 °C}$ at 1 atm. Calculate the van’t Hoff factor for the solute in this solution.
