Use the solubility curve provided on the right to determine the answers to the following questions: Solubility Curves for Selected Solutes How many grams of solute are required to saturate 100 g of water in each of the following solutions? KCL at 80"C b) KCIOz at 90"C NaNOz at 10'C d) SOz at 20 %€ NH-Cl at 70"C 150 140 130 120 110 NaNO; 2 100 1 What is each of the solutions below: saturated, unsaturated or supersaturated? All of the solutes are mixed with 100 g of water: 40 g of NaCl at 50"C 30 g of . NH; at 30"C 70 g of _ HCI at 20"C 80 g of _ KNOz at 60"C 80 g of NH,Cl at 80"C KNO, Hcll NHaCl NHG Kcll Nacl KtIO; 40 I00 Temperature (PC) How many grams of KNOs per 100 g of water would be crystallized from a saturated solution as the temperature drops from: 80"C to 20"C 60"C to 40"C 50"C to 30"C 80"C to 0"C 50"C to 10"C At what temperature are the following solutes equally soluble in 100 g of water? NaNOz and KNO: NH-CI and HCI NH: and KNO: KCIOz and NaCl 10. Which three solutes show a decrease in solubility with increasing temperature?
