Hello...would someone please help me with (SOME OF) these questions?
Thank you very much!!!
1.Will hydrophilic colloidal particles adsorb ions in water?
2.If there aren't other ions in a colloid solution, how will colloidal particles stabilize themselves?
3.How do colloidal particles decide which kind of ions to adsorb?(cations or anions,I mean)
4.Why does adding an electrolyte into a colloid solution disturb the stability of the solution?
(Cations and anions exist simultaneously. If there are already some ions in the solution..
why, then, should we add MORE ions to disturb the stability?)
5.If we try to stabilize a colloid solution by dialysis, will the solution become charged?
(Some ions are adsorbed by colloidal particles and cannot pass...???)
Thank you again!!!

There's a decent bit on this in Atkins' Physical Chemistry

Ah, thank you^^...but I can't get that book in Taiwan...
Anyway, you mean I should find a physical chemistry book? I'll try...
If someone can answer just some of the questions above INSTANTLY, I'll be grateful for that...
Thanks...

A physchem book is your best bet, or a specific one on liquids & solutions, or soft condensed matter.
Even if someone gives you quick answers to your questions on this forum, I highly recommend that you do some reading on this, so that you understand the underlying principles behind it.
I found this on google, I haven't read it, but it sounds like it will help you http://wefcol.vub.ac.be/wefcol/lectures/hanoi/h1.pdf (takes a while to load, it's 24 pages long)
also, read about DLVO theory
