Question

Consider the reaction CaSO4(s) -->Ca2+(aq) +SO42-(aq)   At 25 oC the equilibrium constant isKc= 2.4 x 10-5 for this reaction. A) If excess CaSO4(s) is mixed with water at 25oC to produce a saturated solution ofCaSO4,      what are the equilibriumconcentratio of Ca2+ and SO42-? B) If the resulting solution has a volume of 3.0 L, whatis the minimum mass of CaS)4(s) needed to achieveequilibrium?
