A 20-mol-% LiCl/H2O solution is made by six different mixing processes:
(a) Mix LiCl(s) with H2O(l).
(b) Mix H2O(l) with a 25-mol-% LiCl/H2O solution.
(c) Mix LiCl ⋅H2O(s) with H2O(l).
(d) Mix LiCl(s) with a 10-mol-% LiCl/H2O solution.
(e) Mix a 25-mol-% LiCl/H2O solution with a 10-mol-% LiCl/H2O solution.
(f) Mix LiCl⋅H2O(s) with a 10-mol-% LiCl/H2O solution.

Mixing in all cases is isothermal, at 25°C. For each part determine the heat effect in J·mol−1 of final solution.
