Unit 2 - Reactions in Aqueous Solutions

Learning Targets

  • LO 1.4 The student is able to connect the number of particles, moles, mass, and volume of substances to one another, both qualitatively and quantitatively.

LO 1.17 The student is able to express the law of conservation of mass quantitatively and qualitatively using symbolic representations and particulate drawings.

LO 1.18 The student is able to apply conservation of atoms to the rearrangement of atoms in various processes.

LO 2.8 The student can draw and/or interpret representations of solutions that show the interactions between the solute and solvent.

LO 2.9 The student is able to create or interpret representations that link the concept of molarity with particle views of solutions.

LO 2.14 The student is able to apply Coulomb’s Law qualitatively (including using representations) to describe the interactions of ions, and the attractions between ions and solvents to explain the factors that contribute to the solubility of ionic compounds.

LO 3.1 Students can translate among macroscopic observations of change, chemical equations, and particle views.

LO 3.2 The student can translate an observed chemical change into a balanced chemical equation and justify the choice of equation type (molecular, ionic, or net ionic) in terms of utility for the given circumstances.

LO 3.3 The student is able to use stoichiometric calculations to predict the results of performing a reaction in the laboratory and/or to analyze deviations from the expected results.

LO 3.4 The student is able to relate quantities (measured mass of substances, volumes of solutions, or volumes and pressures of gases) to identify stoichiometric relationships for a reaction, including situations involving limiting reactants and situations in which the reaction has not gone to completion.

​LO 3.7 The student is able to identify compounds as Bronsted-Lowry acids, bases, and/or conjugate acid-base pairs, using proton-transfer reactions to justify the identification.

LO 3.8 The student is able to identify redox reactions and justify the identification in terms of electron transfer.

LO 3.9 The student is able to design and/or interpret the results of an experiment involving a redox titration.

LO 3.10 The student is able to evaluate the classification of a process as a physical change, chemical change, or ambiguous change based on both macroscopic observations and the distinction between rearrangement of covalent interactions and noncovalent interactions.
