Americans, I need your help - Hydrogen Sulfide Tests?

<p>I was studying Chemistry SAT II from Barron's and came across the laboratory section. It mentioned Hydrogen Sulfide Tests (for salts of metals). Do I need to know this for the chemistry test?</p>

<p>I don’t think they were on the May one, at least, not from what I can remember.</p>

<p>I thought so. What about the flame tests (Li, Na, etc.), do you need to know those?</p>
