If 1 liter of the Pentland field formation water (see lecture power-point) is mixed with equal volume of seawater and noting that BaSO4 solubility under that condition is 2 mg/liter, how much BaSO4 precipitate would be there? (Hint: watch out for which ion is the limiting factor)( NOTE: Ksp (BaSO4) is 1x10-10 Atomic weight of Ba is 137, and molecular weight of SO4 is 96;
