Day 25 skills review

DAY 25, Terms to know:

Sections 13.2, 13.1, 13.4, 9.1, 9.2 solution, solvent, solute, solvation, solute-solute interactions, solvent-solvent interactions, solvent-solute interactions, miscible, saturated solution, unsaturated solution, supersaturated solution, Henry’s Law, electrolyte, precipitate, molecular equation, ionic equation

DAY 25, Specific outcomes and skills that may be tested on exam 4:

Sections 13.2, 13.1, 13.4, 9.1, 9.2

• In a given solution, be able to identify the solvent and the solute Be able to describe what interactions must be broken and formed to dissolve a substance and under what conditions that dissolving process will be endothermic versus exothermic
• Be able to explain WHY like dissolves like from the point of view of breaking and forming intermolecular attractions
• Given two substances, be able to predict whether they are likely to be miscible or not and explain WHY
• Be able to describe how to make a saturated, unsaturated, or supersaturated solution
• Be able to describe and explain how and why the solubility of a solid dissolved in a liquid changes (generally) upon increasing temperature
• Be able to describe and explain how and why the solubility of a gas dissolved in a liquid changes upon changing the temperature, volume of gas, or moles of gas
• Be able to identify a compound as a strong electrolyte, weak electrolyte, or nonelectrolyte and EXPLAIN your identification

Complete these problems outside of class until you are confident you have learned the SKILLS in this section outlined on the study guide and we will review some of them next class period.  13.9  13.11  13.123  13.135  13.37  13.127  9.9  9.11  9.13  9.23  9.115  9.117  9.125  9.167
