Hi. I have a question about the term, "Ionic liquid" When I researched the papers, I found the word "Ionic liquid" in many papers. First, I thought the ionic liquid just means the solution that solvent is ionized. But as I read other papers, I found that people don't mean ionized solution as ionic liquid. For example... What is a difference between (1) NaCl ionic liquid and..... just a (2) solution that I pour NaCl powder in DI water and just it with stick ??? I hope I find the answer here.... Thanks!
