Quick Chemistry Question.

[ICRS]

I remember from chemistry when you most ionic compounds such as salts they disolve into their anion and cation components. So if you mix NaCL and KI in water I it should form a solution of NA+(aq),CL-(aq),K+(aq),I-(aq). Now my question is, when you evaporate the water away, would you still only have NACL and KI, or would you now get NACL, KI, KCL, and NAI.

There is no such thing as KI as they can't make a salt due to different chares, nor NaI, nor KCl

What do you mean KI is added to table salt sometimes to iodize it, KCL is a salt substitute sold in stores.

What I mean is that's not preferred ionic bonds your solution prefers to make since charges from cation and anion to not balance. It will form NaCl again because its the lowest energy state.

What if I add NaI and KCL to H2O, would NaCL then form after it evaporates?

potassium iodine doesnt exist?



Yes you will get both KCL and NaCl, however if I remember correctly,

KI + __Cl + H2O --->> KCl + I3- +H2O ---> KCl + I2

I think you will get some iodine.

WTF are you talking about?

OP, yes they'll probably all mix up in solution, and you'll have a mix of the salts when the water evaporates.

I hesitantly agree
