Not quite... Pot Ash is actually impure Potassium carbonate, or what can
be leached out of a heap of fireplace ashes. Besides the carbonate, this
material also contains some of the hydroxide, known as caustic potash.

Not quite... Potassium carbonate could, conceivably, recharge a cationic
exchange resin just as well as the chloride, but I would not recommend
agricultural grade potash.

Not quite... No appreciable reaction between the aqueous salts; the old
copper nail in the potassium chloride sollution trick never drew much of
a crowd, however the old potassium nail in the copper chloride solution
trick is guarenteed to bring the house down (literally)!
