Potions help - pH and buffers

I will be missing my Chemistry Lab next week. The teacher will let me submit as much of the lab as I can by this Thursday night. Without the actual lab, it's not entirely possible, but I'll try.

I suppose I'm looking for websites where I can glean clues so I can make some guesses on the labsheet.

One of the tests: In separate beakers of 100mL water, we are to dissolve aspirin, AlkaSeltzer, Tylenol, Bufferin, and Milk of Magnesia. Once dissolved, we are to pour 30mL of each solution into two other beakers. Test its pH. Then add strong acid HCl to one and strong base NaOH to the other. Logging the pH levels for each, we are to determine if the medicines are buffered or not. (Based on the fluctuation of the pH levels.)

Any ideas how to find this information?

sign ideas?

Got any ideas for protest signs for the National Equality March and/or the Saturday HRC dinner picketing?

I see that the Westboro folks plan to picket at the HRC dinner, too. I really loved the "I'm With Stupid ===>" sign that someone held up next to the Phelps' folks. I'm thinking maybe of some word bubble or thought bubble to hold above their head.
