1. Which one of these is the best representation of a saturated solution? Be sure to explain why. 2. The following compounds dissolve readily in water. If you prepare a 0.100 M aqueous solution of each of these, which one will have the greatest conductivity? Which one will have the lowest conductivity? (How do you know?) MgSO4 (Epsom salts: used in baths to relieve inflamation, pain and relax the body) CaCl2 (used to melt ice on roads in the winter) Sugar (sucrose: C2H22011) CH3COOH (acetic acid) NaHCO3 (sodium bicarbonate; baking soda) NaCI (table salt) 3. The mole fraction of carbon dioxide (xcoz) in water is 0.25. What is the mass fraction of CO2 in this solution? Determine the molarity of CO2 in the solution (Assume the density of the solution is 1g/mL). 4. A 30.00 mL sample of Mg(NOs)2 was diluted with water to 60.00 mL. A 20.00 mL sample of the dilute solution contained 0.300 M NO3 (aq). What was the concentration of Mg(NO3)2 in the original, undiluted solution? 5. A solution is prepared by dissolving 10.0 g of NaBr and 10.0 g of Na2SO4 in water to make a 100.0 mL solution. This solution is then mixed with 75.0 mL of a 0.800 M aqueous solution of AlBr3. Calculate the concentration (M) of Na and Br in the final solution.Explanation / Answer
1) Figure C represent a saturated solution.
A solvent that made soluble maximum amount of solute in it and no more solute can be solubilized gives rise to a saturated solution. In other words, a satutated solution has maximum possible amount of solute dissloved in it and further addition of solute remains in undissolved state. As represented in the figure, fig C contains some undissolved solute lying at the bottom of the beaker, i.e.- it has solubilised the maximum possible amount of a solute, hence it represents a saturated solution.
