A solution of a substance is said to be saturated if it cannot dissolve any more of the substance in it. Bharti carried out an experiment to see the effect of temperature on a saturated solution. She took 100 g of water in two beakers. She then dissolved sugar in one and salt in the other slowly by adding small amounts each time and stirring, until the solution became saturated. The temperature of the solution was maintained at 20 °C. Sherepeated the same experiment at 60 "C and 100 °C. This is what she observed. Temperature Amount of substance required to make a saturated solution (g) Salt Sugar 20 °C 35 205 60°C 39 287 109 °C 40 487 What can be concluded about the amount of substance dissolved to make a saturated solution, at different temperatures of the solution? A. Asthe temperature increases, mcre amountof substance is needed. B. As the termperature increases, same amount of substance is needed. C. As the temperature decreases, moreamountof substance isneeded. D. As the temperature decreases, same amountof substance is needed. 景

Magnesium sulfate (MgSO4) has a solubility of 38.9 g/ 100 g H2O at 30C. A solution is prepared by adding 9.50 g of MgSO4 to 25.0 g of water at 40C. A homogeneous mixture is obtained. Is the solution saturated, unsaturated, or supersaturated? One gram of magnesium sulfate is added to the solution cooled to 30C. Would you expect some of the MgSO4 to precipitate? If so, how much? If not, how much more MgSO4 can be added before precipitation takes place?
Cooking A cook prepares a solution for boiling by adding12.5 g of NaCl to a pot holding 0.750 L of water. Atwhat temperature should the solution in the pot boil?Use Table 14.5 for needed data.
Suppose that you are closing a cabin in the north woods for the winter and you do not want the water in the toilet tank to freeze. You know that the temperature might get as low as 30. C, and you want to protect about 4.0 L water in the toilet tank from freezing. Calculate the volume of ethylene glycol (density = 1.113 g/mL; molar mass = 62.1 g/mol) you should add to the 4.0 L water.

The solubility of lead nitrate at 100C is 140.0 g/100 g water. A solution at 100C consists of 57.0 g of lead nitrate in 64.0 g of water. When the solution is cooled 10C to 25.0 g of lead nitrate crystallize out. What is the solubility of lead nitrate in g/100 g water at 10C?
Patients undergoing an upper gastrointestinal tract laboratory test are typically given an X-ray contrast agent that aids with the radiologic imaging of the anatomy. One such contrast agent is sodium diatrizoate, a nonvolatile water-soluble compound. A 0.378-m solution is prepared by dissolving 38.4 g sodium diatrizoate (NaDTZ) in.l.60 102 mL water at 3 1.2C (the density of water at 31.2C is 0.995 g/cm3). What is the molar mass of sodium diatrizoate? What is the vapor pressure of this solution if the vapor pressure of pure water at 31.2C is 34.1 torr?
