Question
Two beakers are placed in a small closed container at 25 °C. One contains 461 mL of a 0.112 M aqueous solution of BaCl2; the second contains 293 mL of a 0.271 M aqueous solution of BaCl2. Small amounts of water evaporate from both solutions. As time passes, the volume of solution in the second beaker gradually................... a) increases or b) decreases
