A saturated calciumhydroxide solution contains 1.2 × 102 M [Ca] and 2.4 × 102 M [OH] at 298K, which are at equilibrium with the solid in the solution. The solution isquickly heated to 400 K. Calculate the AG, at 400 K with the concentrations,AH,, and AS, given and state whether calcium hydroxide will precipitate orbe more soluble upon heating.
