Monday, November 9 th Grab a blue sheet from on top of the projector. Take out: packet -Review questions notes Write the chemical equation and the K a expression for the ionization the following acids in aqueous solution: o HBrO 2 o HC 3 H 5 O 2

Announcements Due Tomorrow, 11/10: Problem Set 1 Due Thursday 11/12: Le Chatelier’s Principle lab, Problem Sets 2 and 3, Effects of K a prelab (will be passed out tomorrow) Friday, 11/13: Quiz Due Monday, 11/16: notes Due Tuesday, 11/17: Review questions 18-25, Problem set 4 Due Wednesday, 11/18: Problem set 5 Thursday, 11/19 (sorry about the typo): Chapter 16 test

Lactic acid (HC 3 H 5 O 2 ) has one acidic hydrogen. A 0.10 M solution of lactic acid has a pH of Calculate the K a.

A 0.200M solution of a weak acid HA is 9.4% ionized. Using this information, calculate [H + ], [A - ], [HA], and K a for HA.

A particular sample of vinegar has a pH of Assuming that acetic acid is the only acid the vinegar contains (K a = 1.8x10 -5 ), calculate the concentration of acetic acid in the vinegar.

The active ingredient in aspirin is acetylsalicylic acid (HC 9 H 7 O 4 ), a monoprotic acid with K a = 3.3 × 10 −4 at 25°C. What is the pH of a solution obtained by dissolving two extra-strength aspirin tablets, containing 500. mg of acetylsalicylic acid each, in 250. mL of water?

Rest of Period Be productive! You have all of your directions and due dates Tomorrow: similar to today, but with bases – a few practice problems, and then time to work
