🤓 Based on our data, we think this question is relevant for Professor Carlson's class at UWM.

Solution: A solution contains 0.015 M Ba2+ and 0.015 Ag+ . Na2SO4 (s) is slowly added to the solution. Does silver sulfate or barium sulfate precipitate first? How much of the first precipitated ion remains when the second ion begins to precipitate? a. BaSO4, 1.1 x 10 -3 Ba + remains b. BaSO4, 1.5 x 10 -9 Ba+ remains c. BaSO4, 7.6 x 10 -2 Ba+ remains d. Ag2SO4, 7.6 x 10 -2 Ag2+ remains e. Ag2SO4, 1.5 x 10 -9 Ag2+ remains 

Problem

A solution contains 0.015 M Ba2+ and 0.015 Ag+ . Na2SO4 (s) is slowly added to the solution. Does silver sulfate or barium sulfate precipitate first? How much of the first precipitated ion remains when the second ion begins to precipitate?

a. BaSO4, 1.1 x 10 -3 Ba + remains

b. BaSO4, 1.5 x 10 -9 Ba+ remains

c. BaSO4, 7.6 x 10 -2 Ba+ remains

d. Ag2SO4, 7.6 x 10 -2 Ag2+ remains

e. Ag2SO4, 1.5 x 10 -9 Ag2+ remains
