If I mix water in a cup with sugar at some stage the solution will become saturated and no more sugar will dissolve into the water. If I now add salt to the solution will the salt dissolve into the water or is the solution already saturated?
I have not tried an experiment as I cannot figure out how to measure the dissolved component of the 2, intuitively I think that some salt will dissolve, but not as much as in a pure salt water mixture.
