Just because I was interested in what would happen, I mixed a 50/50 solution of salt and water and put it in the freezer until it froze solid, I checked on it about three days later. I then added tap water on top of it and put it back in the freezer. Checking back on it, about two weeks later, there is the frozen salt solution at the bottom, and solid ice at the top, but in between the layers is a layer of completely clear, liquid water. I’m just looking for an explanation as to why.
