THE LAB...

All right, everyone. I'm pretty sure everyone is pretty confused on what we are supposed to do for THE LAB, so I'm going to try and put out there what I think we are supposed to do. Scully, I'm counting on you especially to call me out for being wrong on anything.

Ok, I'll start off with some definitons:

1. titration-adding NaOH to KHP until it turns a "the lightest shade of pink"
2. KHP-potassium hydrogen phthalate; it's the stuff that look like big salt
3. NaOH-sodium hydroxide; it's what goes in the buret, and is located in a keg-thing by the microwaves
4. phenolphthalein-[fee-nawl-thal-een] stuff that is in X-lax (not the lacrosse possition!) it's what makes the titration, your mixture of NaOH and KHP turn pink

Next off, some general starter. I'll leave some stuff some other guys to comment though

1. --get 2, TWO, samples of KHP; keep it as close as you can to 0.50 g, but it's better to go lower
2. --dissolve KHP in a beaker of ionized water and 2, TWO, drops of pheolthinggummy; swirl it around until it is completely dissolved
3. --while one guy is doing step two, the other can use the tiny beaker Dr. B gave us, fill it with NaOH from the keg-thing, and pour it into the buret.
4. initial NaOH volume reading=0.something(measure from zero); record this before you titrate;
5. stick the beaker of dissolved KHP under the buret and open the valve. THIS IS YOU TITRATING
6. When you're titrating, let in 5 or so mL of NaOH, then swirl, let in another 5 and swirl, let in another 5 and swirl, AND THEN start adding it in drops sssslllooooowwlllllyyyyyyyy (you add it slowly because the point where it is "the faintest shade of pink" arrives really fast)
7. after you titrate, make your Final NaOH volume reading
8. Final NaOH volume reading= somewhere in the teens(measure from zero)

Now all you do is repeat the steps, except you don't have to necessarily add more NaOH. You can just go from where the last one was. You just have to take that into account in your volume readings.

Ok, I really hoped that helped some of you. If it didn't, well I went to St. Ann, you can't expect me to be that good.

AND IF YOU THINK I'M WRONG, FREAKIN' TELL ME. INFALLIBLE IS NOT ME. that guy's German, and is probably just waking up right now to celebrate some Jesus in Rome. If he isn't somewhere else in the world, but I digress.

goodnight!
