Adv. Chemistry - 11/21 - Determination of [H+] via Titration with NaOH

Today, details count!

You will determine [HCl] by titration with 0.05297MNaOH, using phenolphthalein as your indicator. Notice, we know our [NaOH] to a high degree of certainty. Calculate the pH of the NaOH solution before you start your first titration.

We will also begin analyzing lab data using statistical methods to determine if an outlier may be rejected. We use a technique called Dixon's Q-Test to do that. The Q-Test works better the more trials you have. Today you will perform five trials.

When you come to class on Tuesday you should have:
