Chemical Systems and Equilibrium (SCH4U Unit 3)



Primary Learning Goals

  □

I can explain the concept of dynamic equilibrium and how the concept applies to various physical and chemical equilibria.

  □

I can write the equilibrium constant expression for various equilibria, and relate the magnitude of an equilibrium constant to the position of a system at equilibrium.

  □

I can calculate the equilibrium constant for a chemical system using the equilibrium law expression.

  □

I can use the reaction quotient for a chemical system to predict how the system is changing.

  □

I can calculate the equilibrium concentrations of reactants and products, given the initial conditions of the system.

  □

I can apply Le Châtelier’s principle to predict how various factors would affect a chemical system at equilibrium.

  □

I can use the solubility product constant to calculate the solubility of a solute in water, and vice versa.

  □

I can contrast strong and weak acids and strong and weak bases using the concept of dynamic equilibrium, and compare the strengths of acids and bases based on their ionization constants.

  □

I can calculate the pH of solutions of strong acids and weak acids.

  □

I can calculate the pH of solutions of string bases and weak bases.

  □

I can describe the Brønsted-Lowry theory of acids and bases, and recognize acids and bases and their conjugate bases and conjugate acids.

  □

I can describe the chemical characteristics of a buffer solutions, and explain how a buffer solution resists changes in pH.
