Does the concentration of the solution change if the volume changes? (1 Viewer)

[jamesfirst]

c = n/V


If 500mL of a particular solution was reduced to 300mL

would the concentration differ ???


ie does the number of mole for the solution stay constant

I haven't done chem in a while so I might be wrong.

If you reduce the volume then concentration will not change.
If you increase the volume by adding distilled water or whatever then yes concentration will decrease.
If you reduce the volume then the number of moles will decrease.
If you increase the volume by adding more distilled water then the number of moles will remain unchanged.

Sounds about right.

Yeah I think I remember my teacher saying that the concentration does not change if the volume is altered... but I can't remember so I got confused and had to ask.

thanks
