1010 - Concentration |
1004 - Distinguish between concentration and solubility. |
1006 - Define molarity, molality, and mole fraction. |
1008 - Identify the advantages of molarity, molality, or mole fraction in describing concentration. |
1010 - Calculate molarity, molality, and mole fraction from quantities of solute and solvent. |
1020 - Use molarity, molality, or mole fraction as a conversion factor. |
1030 - Convert molarity, molality, or mole fraction to mass percent. |
1040 - Colligative Properties |
1010 - Define, identify and give examples of colligative properties. |
1040 - Use BP elevation and FP depression data to determine the molar mass of solutes. |
1045 - Define and explain osmotic pressure. |
1050 - Predict the direction of solvent flow across a semi-permeable membrane from solution concentration. |
1110 - Define an ideal solution. |
1120 - Use Raoults law to relate the vapor pressure of a pure substance to the mole fraction of that substance in solution and vapor pressure of that solution. |
1130 - Apply Raoults law to a solution with multiple volatile components. |
1140 - Predict and describe deviations from Raoults law based on very strong or very weal solute-solvent intermolecular forces. |
1145 - Identify the Vant Hoff factor (i) for a strong electrolyte and use it for calculating colligative properties. |
1150 - Explain observed deviation of i (Vant Hoff factor) from what would be expected by stiochiometry. |
1050 - Colloids |
1010 - Recognize mixtures may be heterogenous, homogenous (solutions), or colloidal dispersions (colloids). |
1020 - Explain why colloids do not settle (like heterogenous dispersions). |
1030 - Explain why colliods they a hazy or opaque appearance (unlike solutions) which produces the Tyndall effect. |
1040 - Predict which type of mixture will likely form based on diameter of solute (less than 1 nm, greater than 1000 nm, or between). |
1050 - Classify a mixture by properties of clarity and tendency to settle. |
1060 - Describe the formation of micelles in solution. |
