Problem 25P
(a) Use the following data to calculate the combined heat of hydration for the ions in sodium acetate (NaC2H3O2):
ΔHlattice = 763 kJ/mol ΔHsoln = 17.3 kJ/mol
(b) Which ion contributes more to the answer to part (a)? Why?
ANSWER:
Solution 25P:
Step 1:
Here, we are going to calculate the heat of hydration for the ions in sodium acetate (NaC2H3O2)
We know that, the enthalpy changes for the solution () is equal to the sum of the heat of hydration () and heat of solute ().
Thus, the combined heat of hydration for the ions in sodium acetate (NaC2H3O2) -745.7 kJ/mol.
