<p>Okay so without any sheet of polyatomic ions and such how do i do this?</p>
<p>(A) X+
(B) X2+
(C) X3+
(D) XO3 2
(E) XO4 2</p>
<li>A type of ion found in sodium acetate</li>
</ol>
<p>I dont know the formula for acetate…</p>
<p>do i need to know it???</p>
<p>also which ion do they want? SODIUM OR ACETATES?</p>
<p>you should probably memorize the formulas for all the polyatomic ions. Otherwise the test is going to be very difficult without it.</p>
<p>To answer the question, sodium acetate is NaC2H3O2. It breaks down into Na+ and C2H302 -. Since, X- isn't an answer choice but X+ is, X+ is the answer.</p>
<p>so i have to memorize em all? wow dam</p>
<p>there are like 50 though</p>
<p>does anyone know which ones specifically?</p>
<p>it's actually closer to like 20.</p>
<p>I'm actually kind of surpised your chem teacher didn't make you memorize them in class.</p>
<p>And most of the polyatomic ions are common sense.</p>
<p>I have this sheet given to me by my Chem teacher with a list of ions </p>
<p>It goes by +1 Ions, -1 ions , -2 ions</p>
<p>And all the ions on that page come down to 40 + </p>
<p>I dont know which ones exactly to study </p>
<p>Does anyone have a list on them? Or some site with exact or close to the ones i need to study?</p>
<p>All help is appreciated </p>
<p>Yeah my chem teacher was nice i guess?? She gave us a sheet with all of them hah</p>
<p>lol just memorize all of them... it'll make your life ALOT easier especially if you're planning on doing ap's. just make flashcards for them and you should get them down pretty quickly. best of luck!</p>
<p>the most common polyatomic ions:</p>
<p>PO4 3- Phosphate
CO3 2- Carbonate
NO3 1- Nitrate
O2 2- Peroxide
CN 1- Cyanide
SO4 2- Sulfate
MnO4 1- Permanganate</p>
<p>dont forget about nitrite, your chlorates and chlorites too!</p>
