Question

39.Which of the following statements correctly describe the heat of solvation for a solution process? Mark all correct answers. (a)The heat of solvation is the enthalpy change that occurs when a solute particle is surrounded by solvent molecules. (b)The heat of solvation depends only on the solvent in the solution. (c)The heat of solvation is the overall enthalpy change that occurs when a solution forms. (d)The heat of solvation is called the heat of hydration if water is the solvent. (e)In general, ions with greater charge densities will have more negative heats of hydration.

Answer 1

The correct statements about the heat of solvation for a solution process are:

(a) The heat of solvation is the enthalpy change that occurs when a solute particle is surrounded by solvent molecules.

(d) The heat of solvation is called the heat of hydration if water is the solvent.

(e) In general, ions with greater charge densities will have more negative heats of hydration.

So, statements (a), (d), and (e) are correct.
