c/c_Chimie_12e_Relations quantitatives

quantitative problems using relationships between variables such as:

• in equilibrium systems (e.g., K_eq, initial concentrations, equilibrium concentrations)
• in solutions (e.g., K_sp, prediction of precipitate formation, calculating the maximum allowable concentration)
• in water as an equilibrium system (e.g., K_w, [H3O⁺] or [OH^-], pH and pOH)
• in acid-base systems (e.g., K_aa, K_b, [H3O⁺], [OH^-], pH and pOH)
• in a titration (e.g., pH of a solution, K_a of an indicator)
• pH in hydrolysis of ions in salt solutions
• in a redox titration (e.g., grams, moles, molarity)
• in an electrochemical cell (e.g., E⁰)
