- Project Question: well hello, ok well im doing a solar powered water cleaner and its all about evaporation... im going to clean and make fresh water from artificial coloring, salt and mud... and oh ya im mixing water with these, but any way when i try to clean the a.coloring and when i get the water after a few hours the water still has some of the coloring in it... why is that? is it like the atoms in the h20 get colored or something?

need help
when i put artificial coloring into water and i tryed to clean the water with this device that i made and it works by evaporatation but when it cleaned the water the a. coloring was still there y??? is it like the atom in the h20 gets like colored??? oh no !!!

Re: need help
I'm not sure I follow exactly what you observed.
If you disolve something (say food coloring) in water, then you have something called a solution. Water isn't the only thing that can evaporate (change into a gas phase). If you heated the solution to form water vapor and then condensed the vapor in another container and the color came with it, then you also evaporated your coloring agent and condensed it as well.
If you observed that the color did not end up in your condensate, then the coloring agent didn't evaporate and condense. I suspect that you were hoping to separate them, so I suspect that this wasn't what you observed.
To figure out what actually happened, you need to look up the chemical properties of your coloring agent, particularly its vapor state properties.
