Learning Objectives 1/24/08 You should: 1. be able to calculate equilibrium constants given the equilibrium concentrations or partial pressures of all reactants and products. 2. be prepared to calculate equilibrium concentrations or partial pressures of reactants and products given their initial concentrations and the corresponding equilibrium constant ( K c or K p ) for the reaction. 3. know how to use the initial concentrations/partial pressures of reactants and products with the equilibrium concentration/partial pressure for one of the reactants or prod - ucts to determine the equilibrium concentrations/partial pressures of the other reac - tants and products and the equilibrium constant for the reaction. 4. understand how nonelectrolytes, strong electrolytes, and weak electrolytes differ in their behavior when dissolved in water. 5. be able to write net ionic equations. 6. be able to use the pH scale to express the hydronium ion concentration and know how to convert between pH and [H 3 O + ]. 7. know the pH criteria for acidic, neutral, and basic aqueous solutions at 25 °C. 8. know the relationship between pH and pOH in aqueous solutions. 9. memorize the seven common strong acids (HCl, HBr, HI, HNO 3 , H 2 SO 4 , HClO 4 , HClO 3 ). 10. know that the hydroxides of the alkali metals (Group I), LiOH, NaOH, KOH, RbOH, CsOH, FrOH, are strong bases. 11. understand autoionization and be able to write an equation for the autoionization of water and the corresponding equilibrium expression for K w . 12. know how to use K w to find [H 3 O + ] or [OH - ]. 13. be able to use acid and base ionization constants ( K a and K b ) to find equilibrium concen - trations of [H 3 O + ] or [OH - ]. 14. understand when and how to use approximations in equilibrium calculations. 2 Follow-up to Lecture 5 (1/22/08) Which value of the gas constant R should be used?
