At 0 oC, the solubility of sodium acetate in water is 36.1 g per 100 g of water and at 40 oC, the solubility is 66.4 g per 100 g of water. A 100 g sample of sodium acetate is dissolved in 250 g of water at 40 °C. The solution is cooled to 0 °C and a small amount of solid is observed. This solution is ________. - hydrated -saturated -supersaturated - unsaturated

Submit Previous Answers A solid mixture consists of 25.5 g of KNO (potassium nitrate) and 4.5 g of K2SO4 (potassium sulfate). The mixture is added to 130. g of water v Correct Use this solubility curve (Eigure 1) to answer the questions. Crystallization Crystallization is the opposite of dissolution. Since solids tend to dissolve better at higher temperatures, we can cause them to crystallize (i.e., undissolve) from a solution by lowering the temperature. Part B If the solution described in the introduction is cooled to 0 °C, what mass of KNO, should crystallize? Enter your answer numerically in grams. • View Available Hint(s) Figure < 1 of 1 29.65 KNO, / NH,CI Previous Answers Submit 50- Nac X Incorrect; Try Again; 6 attempts remaining 40 30 LiSO, Part C Complete previous part(s) 20 - K,SO, 10- Part D KCIO, 10 20 30 40 50 60 For which salt, K2SO,, LişSO,.

You want to isolate the caffeine content of your hot drink usingrecrystallization. It is known that 100 ml of the hot drink contains 65 g ofcaffeine. The solubility of caffeine in hot and cold water is 660g/L ofwater and 10g/L of water respectively. What is the highest possiblerecovery for this process? Solubility: The amount of solute that can bedissolve per amount of solvent.
