Can sodium be replaced by pottasium in sodium chloride?

Leaching potatoes is very simple.All you have to do is soak them in water for some hours and you're done.This talk about salt and potassium is of no use.

pottasium being more reactive than sodium,can replace the latter from sodium chloride.

Lets see a chemical reaction experimenting this. sodium, pottasium, calsium can be replaced.

If you make a melt of sodium-chloride at 800 degree Celsius and put on top of it liquid potassium (melting point 759 degrees Celsius)and put the whole system under a high enough pressure of dry Argon, then you should be able to connect the potassium as anode and run an electrolysis to replace the sodium by potassium. You probably need a direct current voltage of lower than 1 Volt, because the electronegativity of K and Na is differing not much. (Is a someway useless process, because you might buy instead of sodium-chloride a quantity of potassium-chloride easier.)

yes!..you can replace sodium with potassium...since both have the same valence electron but need some force to carry out coz sodium is more reactive than potassium.
