<p>hahah i dont even remember the second part. But i also put true for it being a stronger base.</p>
<p>HCO3- is the conjugate base of H2CO3 and it is the conjugate acid of CO32-.</p>
<p>H2CO3 + H20 => HCO3- + H+</p>
<p>HCO3- + H20 => CO3- + H+</p>
<p>Observe compounds such as NaHCO3 and Na2CO3.
The CO32- ion can only be produced by HCO3-,while the HCO3- ion can only be produced by H2CO3.</p>
<p>water is a good conducter… haven’t you ever wondered why toaster + water = suicide?</p>
<p>f t for that one, itsasmallworld</p>
<p>Let me get a couple things out of the way:</p>
<ol>
<li><p>The NH3 being a base was FF. NH3 is a weaker base than water. The second statement basically said the same thing. Attracting stronger than water or whatever. So its FF</p></li>
<li><p>HCO3- is the acid because it donates its proton. So what would that make the CO3-2? Was conjugate base an answer (or just “base” was the answer?"]</p></li>
<li><p>Is ShadowRider correct about the buret?</p></li>
</ol>
<p>water is a bad conductor! it said PURE water. the only reason why people say that water conducts electricity is because if YOU’RE in it, there will be salts, which ionize / conduct electricity.
and no, how is it possible that NH3 is a weaker base than water?</p>
<p>because of all the ions in it. water is basically never pure when we use it.</p>
<p>EDIT:/what papercrane said</p>
<p>NH3 is not a strong base, but it is stronger than water which has a Kb of 1.0e-7, while NH3 has a Kb of 1.8e-5.</p>
<p>but water can only conduct if there’s electrolytes in it. pure water is an insulator, i thought</p>
<p>PR said that strong bases are family 1 OH bases H(hydrogen)OH(Hydroxide)</p>
<p>HOH = H20</p>
<p>and NH3 is a stronger base than water which is not really a base</p>
<p>Base was the answer. Hmm why is NH3 a weaker base than water?</p>
<p>and shadowrider, what did you choose?</p>

<p>H is not in the first family</p>
<p>i was so raped by this
i gave up on it</p>
<p>So H20 is NOT a base?</p>
<p>hmm i’m predicting 7 wrong, 1 blank</p>
<p>anyone want to estimate a score for me?</p>
<p>H2O is a base, its amphoteric but your support about why its stronger i don’t think is right because H is not in the first family.</p>
<p>StarportDX, I don’t think you’re correct on the NH3 one. Though NH3 is a “weak base,” its Kb is 1.8x10^-5. The Kb of H20, of course, is only 1.0 x 10^-7. ThereforeI believe the answer would be TTCE.</p>
<p>EDIT: Sorry - didn’t notice that ShadowRider beat me to it.</p>
<p>H2S is polar (got that wrong)
i guess buret is right (got that wrong)
pH of .01M nitric acid is 2</p>
<p>"i guess buret is right "</p>
<p>What about what ShadowRider said?</p>
