<p>oh...remember a saturated solution with NaCl sitting in, and it asks that if you add in more salt, what will happen to the solution
i think i picked increase of solution density...thats the only question i had no idea about</p>
<p>yeah i put density increases but maybe wrong</p>
<p>i put density increases too</p>
<p>no it was something with no change. if it is saturated and you add nothing will happen to the solution. i think it was molarity of the solution doesnt change</p>
<p>I think i put doesn't change, too, but I don't remember for sure.</p>
<p>density increases since mass would increase more than the volume</p>
<p>dang. (10 chars)</p>
<p>the molarity will definitely change because you are adding more NaCl to a saturated NaCl solution</p>
<p>if the solution is saturated it cannot absorb any more nacl and it wont be in the solution</p>
<p>i am absolutley positive.</p>
<p>then how do you explain "supersaturated"</p>
<p>supersaturated is only when i think the solution is heated so it is able to absorb more of the solute. this is only under certain conditions. if the NaCl became supersaturated and then you added more nacl it would dissolve and the molarity would change but this simply was not the case. if it is saturated it cannot hold any more solute.</p>
<p>not sure about this, but NaCl can dissolve over the saturated amount even without temperature increase.
even it didn't dissolve, the density of the mixture (or was it solution?) would still increase.</p>
<p>how was the question written exactly?</p>
<p>Density of the solution can't increase: no more solute goes in. It didn't say "density of the mixture", it specifically said "density of the solution".</p>
<p>i guess you're right.
Rn, not He, has a radioactive characteristic?</p>
<p>there were already crystals from the start, thus it cant be supersaturated</p>
<p>Yes, radon is radioactive</p>
<p>even thuogh helium is a beta particle?</p>
<p>Helium is not a beta particle...it is an alpha particle. The only beta particles there are - are the beta particle are the B0 -1, B0 -1 (electron capture) and B0 1 (positron emission)</p>
<p>B(superscript) (subscript)
B = beta</p>
