(A) Calculate the quantity of that would be obtained if suggestions (1) and (2) in Example 14-4(b) were followed. Use data from Figure 14-10. What mass of water is needed to produce a saturated solution containing 95 g NH₄Cl at 60 °C?

(B) Use Figure 14-10 to examine the solubility curves for the three potassium salts: KClO₄, K₂SO₄, and KNO₃. If saturated solutions of these salts at 40 °C are cooled to 20 °C rank the salts in order of highest percent yield for the recrystallization.

Example 14-4(b)

(b) How might we improve the yield of NH₄Cl?
