olution is formed when the solute uniformly disperses oughout (or dissolves in) the solvent. The process can be scribed though three steps: 1. separation of solvent-solvent particles, 2. breaking of solute-solute particles, and 3. formation of solute-solvent interactions. e overall energy change for the solution process, AHsin, is sum of the enthalpies of the three steps. Whether AHal is dothermic or exothermic depends on the relative magnitudes of ₁. AH₂, and AH3, where the subscript indicates the step in process corresponding to the enthalpy value. A hypothetical solution forms between a solid and a liquid. The values of the thermodynamic quantities involved in the process are shown in the following table. solute Action Enthalpy separation 17.5 kJ/mol 21.8 kJ/mol separation of solvent formation of solute-solvent interactions -90.7 kJ/mol solute Calculate the enthalpy of solution in kilojoules per mole of solute.

Solutions Introduced directly into the bloodstream have to be isotonic with blood; that is, they must have the same osmotic pressure as blood. An aqueous NaCl solution has to be 0.90% by mass to be isotonic with blood. What is the molarity of the sodium ions in solution? Take the density of the solution to be 1.00 g/mL.
Using KF as an example, write equations that refer to Hsoln and Hhyd Lattice energy was defined in Chapter 3 as H for the reaction K+(g) + F (g) KF(s). Show how you would utilize Hesss law to calculate Hso1n from Hhyd and HLE for KF, where HLE = lattice energy. Hsoln for KF, as for other soluble ionic compounds, is a relatively small number. How can this be since Hhyd and HLE are relatively large negative numbers?
