KOH+NaCl -> NaOH+KCl, can it be true ?
« on: September 28, 2007, 10:17:32 AM »
Suppose that I have dissolved 1mol of KOH and 1 mol of NaCl into water. So there have to be 1 mol of K+, 1 mol of Na+,  and so on to Cl-, OH-.

If someone asks me : "What substances are in the solution ?", is that wrong if I answer "NaOH and KCl", or I must say "NaCl and KOH" ?

Is there any way of take NaOH or KCl out of the solution ?
So, we will havew the equation: "KOH+NaCl  -> NaOH+KCl" :D :D

You can only define composition listing ions and their concentrations.

Whether (and how) reagents can be separated depends mostly on their solubility.
