All forms are white solids that are highly soluble in water. With an annual production of 6 million tonnes, the decahydrate is a major commodity chemical product.

No although you were given part manner home with that resolution. I do the next. Ksp CaSO4 = (Ca^2+)(SO4^2-) = 4.93E-5 What must SO4 be to ppt CaSO4? (SO4^2-) = (4.93E-5/0.05) = 9.86E-4M.

Ksp Ag2SO4 = (Ag^+)^2(SO4^2-) = 1.2E-5 What will have to SO4 be to ppt Ag2SO4. That's (SO4^2-) = [1.2E-5/(0.039)^2] = 7.89E-3 M.

Now this is the place the chemical reasoning comes in. If you have got a solution as described in the problem and you add tiny crystals of Na2SO4 (or liquid) a bit at a time, the first salt that exceeds Ksp will ppt first. The above calculation presentations CaSO4 requires LESS SO4 than Ag2SO4; subsequently, CaSO4 will get started pptng first and it's going to proceed pptng as extra Na2SO4 is added UNTIL Ksp for Ag2SO4 is exceeded. When will that happen? When the SO4 gets up to the place? 7.89E-3 in fact. (That's the point at which Ag^2)^2(SO4^2-) > 1.2E-3. So we take 7.89E-3, plug that into CaSO4 Ksp for SO4 and clear up for (Ca^2+). Check my paintings however I bought about 0.006 and that's approximate at that. That's the solution to section a.

b. Therefore you can obtain pure CaSO4 until Ksp for Ag2SO4 is exceeded however not after that. At that point, you get started getting the two mixed sulfates. At that point, Ca^2+ = 0.006M, you had 0.05 to start so that you should have pptd 0.05-0.006 = about (keep in mind this is approximate) 0.044. Percent recovery = about (0.044/0.05)*100 = ? about a little lower than 90%.
