Question:

Consider the following reaction: CaSO _4(s)= Ca ²⁺ _(aq)+ SO ₄ ^2- _(aq). At 25 ^oC the equilibrium constant is K _eq=2.4x10 ^-5 for this reaction.

(a) If excess CaSO _4(s) is mixed with water at 25 ^oC to produce a saturated solution of CaSO ₄, what are the equilibrium concentrations of Ca ²⁺ and SO ₄ ^2-?

(b) If the resulting solution has a volume 3.0 L, what is the minimum mass of CaSO _4(s) needed to achieve equlibrium?
