2. Consider the following two solutions: Solution A has a volume of 1 litre which contains 0.35 moles of acetic acid and 0.25 moles of sodium acetate. The Ka value for acetic acid 1.78 * 10". Solution B also has a volume of 1 litre and it contains 2.8 * 10* mol HCl and 2.84 * 10-4 mol of NaCl. a) Calculate the pH of each of the two solutions. b) What is the pH of each solution after thoroughly...
Consider an aqueous solution that is saturated with lead iodide and lead sulfate and also contains 0.10M Li2SO4 (a strong electrolyte). Write mass and charge balance equations that describe this system. You may assume that sulfate is the conjugate base of a strong acid, and ignore any acid-base characteristics of the sulfate ion or any other species in solution.
A solution of acetic acid (CH3COOH) and water that is 90.% acetic acid by mass is boiling at 109.8 °C. The vapor is collected and cooled until it condenses to form a new solution. Calculate the percent by mass of acetic acid in the new solution. Here's some data you may need: normal boiling point density vapor pressure at 109.8 °C acetic acid 118. °C 1.1 8 mL 648. torr water 100. °C 1.00 1061. torr mL Be sure your...
