Interpretation:
The beaker that gives proper representation when the two pure substances are mixed has to be selected.
Concept introduction:
Like dissolves like principle:‘Like dissolves like’ principle says that polar compounds including ionic compound should be more soluble in polar solvent. Likewise, non–polar compound should be more soluble in non–polar solvent.
Solubility is the quantity of solute (solid, liquid or gas) that will dissolve in a given amount of solvent (solid, liquid or gas) at definite temperature and pressure. Solubility depends on the physical and chemical property of solvent, solute and concentration of the solution.

- Beakers (a), (b), and (c) are representations of tiny sections (not to scale) of mixtures made from pure benzene and pure water. Select which beaker gives proper representation of the result when the two pure substances are mixed.arrow_forwardAt 1 atm, a mixture of octane and methylbenzene boils at 135.8 degrees Celsius with a composition of 60% methylbenzene. The boiling points of methylbenzene and octane are 110.6 and 125.6 degrees Celsius, respectively. Draw a boiling point-composition diagram for the octane-methylbenzene mixture system, including all significant labels.arrow_forwardA certain liquid X has a normal freezing point of 7.10°C and a freezing point depression constant =Kf3.27·°C·kgmol−1. A solution is prepared by dissolving some ammonium chloride (NH4Cl) in 700.g of X. This solution freezes at 6.4°C. Calculate the mass of NH4Cl that was dissolved. Round your answer to 1 significant digit. __garrow_forward
- The solubility of a substance is 30 g per 100 mL of water at room temperature, 50 g per 100 mL of water at 80 ∘C. A student mixed 40 g of this substance with 100 mL of water at room temperature (stage 1), and then heated the mixture to 80 ∘C (stage 2). The mixture is then slowly cooled down to room temperature without any precipitation (stage 3). Finally, the student added a small crystal to the mixture and saw precipitation took place. This mixture is supersaturated at stage 2 heterogeneous at stage 1 homogeneous at stage 4 saturated at stage 3arrow_forwardA physician requests that an iso-alcoholic elixir containing 30.0% alcohol be prepared. How many mL of 10% low alcoholic elixir and 78% high alcoholic elixir must be mixed to prepare 1000 mL of the iso-alcoholic elixir?arrow_forwardA student dissolves 17. g of methanol (CH3OH) in 500. mL of a solvent with a density of 1.11 g/mL. The student notices that the volume of the solvent does not change when the methanol dissolves in it. Calculate the molarity and molality of the student's solution. Round both of your answers to 2 significant digits. molarity = molality = 0 0 010 X 74 ☐☐ 3 " doarrow_forward
- Dilution means adding water to something so that the ratio of solute to solvent is less than in the original solution. Some people say, “Dilution is the solution to pollution.” Do you think this statement true? Could you ever add enough water so that there would be no drink mix—that the water would be the same as in cup #6, pure water? Do you think you could you ever add enough water to a pollutant to make it disappear completely? Why or why not?arrow_forwardDistillation is a physical process of separation of liquids that differ in what physical property?

A How should the correct amount of solute be obtained? Which type of glassware should be used to make this solution (assuming that the accuracy of the concentration Measure out x mol of solid sucrose on a molemet. is important)? OC O Measure out x g of solid sucrose on a balance. O A O Measure out x cm of sucrose with a ruler. Publisharrow_forwardLike solid sucrose, the substances ethanol (C2H6O(l)), ethylene glycol (C2H6O2(l)), and 2-propanol (C3H8O(l)) dissolve in water—giving solutions containing mostly molecules. Write equations showing the dissolving of these three liquids in water.arrow_forwardA certain liquid X has a normal boiling point of 129.30°C and a boiling point elevation constant =Kb2.32·°C·kgmol−1. A solution is prepared by dissolving some barium hydroxide (BaOH2) in 800.g of X. This solution boils at 130.2°C. Calculate the mass of BaOH2 that was dissolved.
