Patients who enter the emergency room dehydrated are usually given sterile saline solution intravenously. The solution administered is isotonic to prevent cell damage. What would happen if the solution was hypotonic?  Group of answer choices A.  Hypotonic solutions have a higher osmotic pressure than that within cells so hemolysis can occur B.  Hypotonic solutions have a lower osmotic pressure than that within cells so crenation can occur can occur. C. Hypotonic solutions have a lower osmotic pressure than that within cells so hemolysis can occur. D. Hypotonic solutions have the same osmotic pressure as that within cells so nothing will happen.

9.The solubility of CaCl2 in water is135g/100 ml.  What would be the best method for preparing a 50.0 mL of supersaturated CaClsolution?
Group of answer choices
A. add 72 g of CaCl2 to 50.0 mL of H2O at 100 °C while stirring at room temperature
B. add 67 g of CaCl2 to 50.0 mL of H2O at 100 °C while stirring at room temperature
C. add 67 g of CaCl2 to 50.0 mL of H2O at 100 °C while stirring until all the solid dissolves, then let the solution cool to room temperature
D. add 72 g of CaCl2 to 50.0 mL of H2O at 100 °C while stirring until all the solid dissolves, then let the solution cool to room temperature
