Due to the potassium ion in potassium nitrate, any firework composition made with potassium nitrate would sport a purple/violet color, unless a strong colorant compound like strontium chloride is added to the composition.
In order to form a potassium nitrate solution, the ionic bond between potassium ions and nitrate ions in the solid potassium nitrate compound needs to be broken. This allows the potassium and nitrate ions to separate and become surrounded by water molecules, resulting in the formation of a potassium nitrate solution.
The conductivity of potassium nitrate depends on its concentration in solution. Generally, potassium nitrate is a strong electrolyte, meaning it dissociates completely into ions in solution and conducts electricity well.
When a cooled saturated potassium nitrate solution is added to water, the concentration of the potassium nitrate decreases making it less likely that he substance will precipitate out of solution.
Pure potassium nitrate can be obtained by dissolving a source of potassium nitrate, such as KNO3 crystals, in water and then filtering the solution to remove any soil or impurities. The filtered solution can then be evaporated to dryness, leaving behind pure potassium nitrate crystals.
The chemical reaction between lead nitrate (Pb(NO3)2) and potassium sulfate (K2SO4) produces solid lead sulfate (PbSO4) and potassium nitrate (KNO3) in solution. The balanced chemical equation is: Pb(NO3)2 + K2SO4 -> PbSO4(s) + 2KNO3.

Just potassium nitrate in water. Aqueous stands for anything with water, so if you take dry potassium nitrate and add some water to it until it dissolves, you have made an aqueous solution of potassium nitrate.

The reaction between barium nitrate (Ba(NO3)2) and potassium phosphate (K3PO4) will form barium phosphate (Ba3(PO4)2) and potassium nitrate (KNO3). The ions left in solution will be potassium (K+) and nitrate (NO3-) ions from the potassium nitrate. The barium phosphate will precipitate out of solution.
The enthalpy of solution of potassium nitrate is +34.9kJ/mol.
Increasing the temperature of the solution, which will allow more potassium nitrate to dissolve. Alternatively, adding more solvent to the solution can also make it unsaturated by diluting the concentration of potassium nitrate.

Silver nitrate + Potassium iodide ----> Silver iodide + Potassium nitrate AgNO3 + KI ----> AgI + KNO3
potassium nitrate would be left was an aqueous solution and lead iodide would be the precipitate
The amount of crystals formed will depend on how much potassium nitrate was dissolved in the solution to begin with. As the solution cools from 60°C to 30°C, potassium nitrate will begin to crystallize out of the solution. The exact amount of crystals can be determined by calculating the solubility of potassium nitrate at 30°C and comparing it to the initial concentration in the solution.
