is it still K(NO3) or does the soluble change it

Soluble KNO3 means that it will dissociate in water to form an ionic mixture of K+ and NO3-. That's all it means.
If your talking about Ksp thats different. That is the solubility constant and it shows when and how much of the solute can dissolve in solvent.

It means when K(N03) is dissolved in water, the reaction is
K(N03) + H2O -----> K (plus 1) + (N03)minus 1 surrounded and separated by a lot of water molecules, by dissociation.
Physically, it is converted from a crystalline solid into positive and negative ions in liquid solution.
Chemically, the solid, not molten, does not conduct electricity is converted into ions in solution that conducts electricity. Also, the potassium ions in the solid is the same potassium ions in solution and the same for the nitrate ions.
Also, chemically, it is difficult to precipitate (ie chemically reacting the ions with other ions) these ions out of the solution because for the most part the salts they form with other common ions are all soluble in water. For example, KCl -potassium chloride is also soluble. If you add HCl to a solution of KNO3, there will be no precipitate. LiNO3 is also soluble.

Pb(NO3)2 + 2KI ----> PbI2 2KNO3 I think that's right... Lead nitrate reacts with potassium iodide to produce Lead Iodide and Potassium Nitrate.

It will disassociate into K+ and NO3- ions.
