Problem: A person drinks 2.0 L of a barium milkshake containing 45 g of barium sulfate (K_{sp} = 1.5 \times 10^{-9}). How close did they come to death from Ba^{2+} poisoning?
Molar masses: Ba = 137.3 amu, SO4^{2-} = 96.1 amu, NO3 = 62.0 amu.
First, consider barium nitrate:
Next, consider barium sulfate:
Problem 1: What mass of AgCl will dissolve in 5.0 L of water (K_{sp} = 1.6 \times 10^{-10}, MW = 143.3 amu)?
Problem 2: What mass of AgCl will dissolve in 5.0 L of 0.250 M NaCl(aq)?
