Crystallization: Use the graph depicting solubility of potassium nitrate (KNO3) in water in Figure 6.5-1 of the textbook to calculate how much KNO3 can be removed as solid (filtered) from a 1-kilogram solution of 60 wt% KNO3 in water (40 wt%) at 65 °C, when it is cooled to 25 °C.
WebSep 19, 2024 · Consequently, adding a small particle of the solute, a seed crystal, will usually cause the excess solute to rapidly precipitate or crystallize, sometimes with spectacular results. The rate of crystallization in Equation \(\ref{13.2.1}\) is greater than the rate of dissolution, so crystals or a precipitate form (Figure \(\PageIndex{1d}\)). WebSep 24, 2014 · See below: Dissolving potassium nitrate in water is an endothermic process because the hydration of the ions when the crystal dissolves does not provide as much energy as is needed to break up the lattice. The enthalpy change of solution or DeltaH_(sol) is the enthalpy change when 1 mole of a solute dissolves to form an "infinitely" dilute …
WebApr 27, 2024 · Potassium nitrate (KNO 3) solution of 2.0% was prepared by dissolving 20 g of KNO 3 in 1.0 L distilled water. To prepare the solution with osmotic potential (OP) of −0.6 MPa, 21 g of PEG (polyethylene glycol) was dissolved in 1 L of water following the equation of Michaelis and Menten (1913) [ 45 ]. Potassium nitrate can be made by combining ammonium nitrate and potassium hydroxide. NH4NO3 (aq) + KOH (aq) → NH3 (g) + KNO3 (aq) + H2O (l) An alternative way of producing potassium nitrate without a by-product of ammonia is to combine ammonium nitrate, found in instant ice packs, and potassium chloride, easily obtained as a sodium-free salt substitute.
