Title: KOH+NaCl -> NaOH+KCl, can it be true ?
Post by: thuanthuan 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.

Thank you, I'm just want to make sure that I'm right :D :D
