The solubility of NH4B is 38g/100 mL of water at 20°C and 65g/100 mL at 80°C. 1. I add a certain amount of NH4Br to a vial of water at 20°C. Much of it dissolves, but there are some grains of salt left in the bottom. I have created [ Select ] . As the temperature rises, all of the remaining solid dissolves. This solution is now [ Select ] 2. I create a saturated solution of NH4Br at 80°C with 300.mL of water and then cool the mixture to 20°C slowly and the solution remains liquid. This is an example of [Select] As soon as I jolt the vial, I destabilize the solution and [ Select ] of salt precipitates out.

(a) If you dissolve 10.0 g (about one heaping teaspoonful) of sugar (sucrose, C12H22O11) in a cup of water (250. g), what are the mole fraction, molality, and weight percent of sugar? (b) Seawater has a sodium ion concentration of 1.08 104 ppm. If the sodium is present in the form of dissolved sodium chloride, what mass of NaCl is in each liter of seawater?

In terms of Raoults law, distinguish between an ideal liquid-liquid solution and a nonideal liquid-liquid solution. lf a solution is ideal, what is true about Hsoln, T for the solution formation, and the interactive forces within the pure solute and pure solvent as compared to the interactive forces within the solution? Give an example of an ideal solution. Answer the previous two questions for solutions that exhibit either negative or positive deviations from Raoults law.
