<p>This is the original reaction -</p>
<p>HF(aq) + KOH(aq) -> H2O(l) + KF(aq)</p>
<p>Why is the net-ionic this? - </p>
<p>HF(aq) + OH-(aq) -> H2O(l) + F-(aq)</p>
<p>But not this? - </p>
<p>H3O+(aq) + OH-(aq) -> 2H2O(l)</p>
<p>Spectator ions should be excluded for the net-ionic, but F-(aq) is also spectator. It makes no sense. A reply would be nice.</p>
<p>I would help sorry, I can’t remember Net Ionic equations from Chem 1. Right now in AP Chemistry, we’re only on chapter 3, we’re still doing review.</p>
<p>HF (aq) is a weak acid, so it doesn’t fully disassociate.</p>
<p>HF is a strong, but unstable acid, therefore it is weak, exactly what the person above says - it doesn’t dissociate completely.</p>
<p>^actually it’s weak and stable- that’s why it doesn’t dissociate.</p>
<p>Thanx for the replies, I get it now.</p>
<p>ONLY STRONG ACIDS (HCl, H2SO4, HBr etc) “dissociate 100%.” So you can’t drop the F in this case because HF is a weak acid. You’ll learn more later about it in acids and bases unit</p>
