<p>i know weak electrolytes dont ionize completely in water, but say you have CH3COOH (acetic acid) and you are doing a net ionic equation. does the H+ separate? or does it stay as acetic acid? Thanks</p>
<p>Because acetic acid is a weak acid, you do not separate H+ and CH3COO- in a net ionic equation.</p>
<p>You have to separate ions only if it's a strong acid.</p>
<p>thanks for the help</p>
<p>i have another question, if you mix tin chloride with iron chloride, what would the products be? i get confused when both reactants have the same ion in it</p>
<p>it sounds like it will form a complex.</p>
<p>i don't think any complex ions will be on the ap exam though.</p>
<p>REALLY? i just learned the complex ion formation. Its pretty simple. Darn i suck at double replacement. er i suck</p>
<p>well double displacement is written differently in net ionic form which BLOWS because it takes a lot to get used to it.</p>
<p>I HATE how we have to write a net ionic. Stupid spectator ions always get me.</p>
<p>Question! When writing a net ionic, do I balance the equation before or after removing spectator ions?</p>
<p>the ap test dont require you to balance the equations</p>
<p>COMPLEX IONS WILL BE ON THE TEST--especially the "predict the reaction" part</p>
<p>You only have space to submit one line of an answer. That is the balanced net ionic equation. I do them in a few steps. Just use the sheet with the questions on it as scrap paper. First predict the products on the first line. Then balance the equation. Then break up compounds into ions if they dissolve. Then remove spectator ions. Then put that line in the answer box!!</p>
<p>Yeah you do. Along with the other 2 changes they made in 2007, you know are required to submit the balanced net ionic equation.</p>
<p>great. this is really really great.</p>
<p>braves09 - if you see something like tin chloride and iron chloride (same anion), regular double replacement doesn't work. Do a redox. Example would be tin(II) chloride + iron(III) chloride. Notice that tin can go up in oxidation number (to +4) and iron can go down (to +2). Therefore</p>
<p>Sn(2+) + 2 Fe(3+) --> Sn(4+) + 2Fe(2+)</p>
<p>complex ions weren't on the exam last year, and the reactions were really easy..... you also have to answer a question about them and i really just dont think they can ask you about a complex ion.....it just doesn't seem like it would be on the ap.</p>
<p>i need to clear up something about H2SO4..</p>
<p>so, the ap graders will take either:</p>
<p>(1) H^+ + HSO4^-</p>
<p>or</p>
<p>(2) 2H^+ + SO4^2-</p>
<p>correct?</p>
<p>yeah you can do either according to my teach</p>
<p>ok, good.. i always choose the latter way because it's usually easier to balance.. and it makes me see other things more easily</p>
<p>ok, thanks gfaith</p>
