Be sure to answer all parts. An aqueous solution of a strong base has pH 10.88 at 25°C. Calculate the concentration of base in the solution: (a) if the base is LiOH. [LiOH] = M (b) if the base is Ba(OH)2. [Ba(OH)2] = × 10 M (Enter your answer in scientific notation.)
Be sure to answer all parts. Commercial silver-plating operations frequently use a solution containing the complex Ag+ ion. Because the formation constant (Kf) is quite large, this procedure ensures that the free Ag+ concentration in solution is low for uniform electrodeposition. In one process, a chemist added 9.0 L of 5.0 M NaCN to 90.0 L of 0.17 M AgNO3. Calculate the concentration of free Ag+ ions at equilibrium. See your textbook for Kf values. × 10 M (Enter your...
