<p>hey can anyone that has PR Chem 07-08 open up their book to page 154. I do not understand a single thing on that entire page.</p>
<p>can someone guide me through it?</p>
<p>my first question on the first example is how the 1.0 M under H+ gets cancelled.
why does the 1.0 M under NO3- stay? what does the 1.0 M to the right of that signify?</p>
<p>i sincerely appreciate it</p>
<p>I don't really understand what they're trying to signify either. But this is what you should know, the HNO3 is a strong acid and because it is 1.0M, it will completely dissociate to produce 1.0M of each product (H+ and NO3-). </p>
<p>Using that amount of H+, you can calculate the pH.</p>
<p>If you showed me what you're talking about (rather than just saying on page 154) I could explain.</p>
<p>The way PR explained all that acid/base stuff was ridiculously confusing for me as well. I basically just memorized the lists of strong acids and strong bases and understood the basics - strong acids dissolve completely to produce an equal amount of each product, etc. And I was fine on the test.</p>
