Does the SAT II Chem test you on normality?

<p>The Barron's SAT II Chem book has a short and confusing section about normality and gram-equivalent mass that I can't understand. Do I really need to learn this for the SAT II Chem test?</p>

<p>Whats normality? I have no clue what that is (maybe i do if you explain it). I got a 770 on it and a 5 on the ap test without knowing what it is if that helps.</p>

<p>thank you</p>

<p>just so you know, in case normality does come up, this is what it is:</p>

<p>normality, in simplest terms, describes how many H+ ions dissociate when a base or acid is created (in relation to the substance's molarity). for example, a 1M solution of HCl would also be 1N, because of the one H+ ion, and a 1 M solution of H2SO4 would be 2N, because of the 2 H+ ions per molar solution.</p>

<p>This is why I don't like Barrons for SAT II Chem. It is chock full of unnecessary information. You should've used PR.</p>

<p>i got that from my textbook, actually..havent got around to studying Barron's in-depth yet</p>

<p>I know, I was referring to the OP... I just meant the fact that Barrons includes normality at all, for the SAT II chem, is a bit ridiculous.</p>
