8)The lattice enthalpy of potassium chloride, (triangle)H° for
KCI(s) + K+ (g) + Cl-(g)
is 717 kJ/mol; the heat of solution in making up 1 M KCl(aq) is +18.0 kJ/mol.
From these data, obtain the sum of the heats of hydration of K+ and Cl-
That is, obtain the sum of (triangle)H° values for
K+ (g)—>K+ (aq)
CI- (g)—> Cl- (aq)
(Triangle)H =kJ/mol
If the heat of hydration of CI- is-338 kJ/mol, what is the heat of hydration of K+?
Heat of hydration=kJ/ mol
