Sufficient solid CaSO4 is added to enough water to produce a solution (if it all dissolves) that is 1×10–3 M Ca2+ and 1×10–3 M SO4–2.  Describe (with evidence) the resultant mixture.  Assume that everything happens at 25∘C without any heating or cooling. Ksp for CaSO4 = 2.4 x 10–5 For this, you must correctly: calculate the reaction quotient from the proposed concentrations interpret the reaction quotient describe the system as unsaturated, saturated or super saturated and state whether or not this system is at equilibrium.
