1. Two bottles of unknown solutions are found in the lab. They were in the acid/base cabinet so it is believed they are an acid or base (this could go horribly wrong!). Here is the information on each unknown. A: concentration 1.44 M; pH=1.60 D: concentration 0.266 M; pH=8.59 Determine what your unknowns! Choices of acids/bases with the Ka! NH4/NH3 Ammonium/ammonia Formic acid/formate Nitrous acid/nitrite Hydrofluoric acid/fluoride Benzoic acid/benzoate Hypochlorous acid/hypochlorite Ka = 3.98E-10 HCO;H/HCO, HNO/NO; HF/F CGH,O2/CH,O; HCIO/CIO Ka = 1.79E-4 Ka = 4.5E-4 Ka = 6.31E-4 Ka = 6.3E-5 Ka = 3.45E-8

Novocaine, C13H21O2N2Cl, is the salt of the base procaine and hydrochloric acid. The ionization constant for procaine is 7106. 15 a solution of novocaine acidic or basic? What are [H3O+], [OH-], and pH of a 2.0% solution by mass of novocaine, assuming that the density of the solution is 1.0 g/mL.
Two students were asked to determine the Kb of an unknown base. They were given a bottle with a solution in it. The bottle was labeled aqueous solution of a monoprotic strong acid. They were also given a pH meter, a buret, and an appropriate indicator. They reported the following data: volume of acid required for neutralization = 21.0 mL pH after 7.00 mL of strong acid added = 8.95 Use the students' data to determme the Kb of the unknown base.
1. Which of the following can act as a Lewis acid? (Hint : In each case, draw the Lewis electron dot structure of the molecule or ion. Are there lone pairs of electrons on the central atom? If so, it can be a Lewis base. Does the central atom lack an electron pair? If so, it can behave as a Lewis acid.) PH3 BCl3 H2S HS−

Mark each of the following statements True or False: a. The conjugate base of a strong acid is always a weak base. b. The conjugate acid of a strong base is always a weak acid. c. The stronger the acid, the weaker its conjugate base, and vice versa.
Two strategies are followed when solving for the pH of an acid in water. What is the strategy for calculating the pH of a strong acid in water? What major assumptions are made when solving strong acid problems? The best way to recognize strong acids is to memorize them. List the six common strong acids (the two not listed in the text are HBr and HI). Most acids, by contrast, are weak acids. When solving for the pH of a weak acid in water, you must have the Ka value. List two places in this text that provide Ka values for weak acids. You can utilize these tables to help you recognize weak acids. What is the strategy for calculating the pH of a weak acid in water? What assumptions are generally made? What is the 5% rule? If the 5% rule fails, how do you calculate the pH of a weak acid in water?
