The heat of solution of KCl is 17.2 kJ/mol and the lattice energy of KCl(s)is 701.2 kJ/mol.Calculate the total heat of hydration of 1 mol of gas phase K⁺ ions and Cl^- ions.

Question

Quizplus · Accepted Answer

The heat of solution is the sum of the lattice energy and the heat of hydration. Therefore, the heat of hydration = heat of solution - lattice energy = 17.2 kJ/mol - 701.2 kJ/mol = -684 kJ/mol.

The Heat of Solution of KCl Is 17
