In a glass, usually the water is at the bottom and the oil on top, depends how you do it, but I did it once with the oil on top and the food colouring slowly went into the oil, depending on how thick the oil is on top, if it is thin, the drop of food colouring will drop through, if it is thick, it will take longer to go through or may not go through at all, so u would have to poke it through with something. Then it gets to the water and just spreads like it normally would in liquid. I made a lava lamp once. Adding water to a glass and a bit of oil on top. You add the food colouring and then add salt. It weights the oil down and then it rises back up. It so awesome. Hope that helps, if it does, please let me know onmy messageboard. Blondie94
nothing maatee the dye just mixes in with the water and then thats it :)
salt becomes dossolved while sand remains as undissolved material at the bottom of container.
mixture
It depends what you added to the mixture. Normally a chemical rxn.
No, that would be a mixture.
to standardise the solution
What is added to graphite to make water soluble pencils
You will have a mixture of zinc and iron filings.

to standardise the solution
Yes. When NaCl is added to water, it forms a solution, which is a homogeneous mixture.
It really depends on what the hot mixture is. It is generally ok.
As it comes from one source, and contains not other ingredients, it is homogenous. To be a 'mixture' it would need to have something added.
