2. Indicators are typically weak acids and the equilibrium can be described as follows: HInd + H:0 H;0* + Ind AH = -2 kJ/mol Assume that Hind is red in color and Ind" is blue in color. a) If a solution is purple (equal concentrations of the two species), what color will the solution tum when some N2OH or other strong base is added to the solution? Explain in terms of the Le Chatelier's principle. b) If a solution is purple (equal concentrations of the two species), what color will the solution tum when the system is cooled in an ice bath? Explain in terms of the Le Chatelier's principle.

Consider a solution prepared by mixing a weak acid HA. HCl, and NaA. Which of the following statements best describes what happens? a. The H+ from the HCl reacts completely with the A from the NaA. Then the HA dissociates somewhat. b. The H+ from the HCl reacts somewhat with the A from the NaA to make HA, while the HA is dissociating. Eventually you have equal amounts of everything. c. The H+ from the HCl reacts somewhat with the A from the NaA to make HA while the HA is dissociating. Eventually all the reactions have equal rates. d. The H+ from the HCl reacts completely with the A from the NaA. Then the HA dissociates somewhat until too much H+ and A are formed, so the H+ and A react to form HA, and so on. Eventually equilibrium is reached. Justify your choice, and for choices you did not pick, explain what is wrong with them.
