As KNO3 (solid), the substance exists as K-NO3. When it is ionized in water it exists as (H2O)nK+ and (H2O)nNO3-. That is, the potassium cation solvated with some water molecules, and the nitrate anion, also solvated to some water molecules. The process of breaking The K-O bond in the salt requires a small amount of energy to be put in, BUT, solvation (binding of the ions to nearby water molecules) is a favourable process, ie, a process that produces energy. The solvation process releases more energy than breaking the K-O bond takes up, so the process of ionisation is energetically favourable.

it's the salt of a strong base and a strong acid.
KOH + HNO3 ---> KNO3 +H2O
if you do the net ionic equation you just get the formation of water.
KNO3 ionizes as K+ & NO3-

Yes it is completely ionized in water as all nitrate
KNO3 >> K+ + NO3-
