Potassium nitrate was found to have a solubility of 120 g in 100 g of water at 80 °C and 50 g in 100 g of water at 25 °C.50 g of water was heated to 80 °C and solid potassium nitrate added until the solution was just saturated?

The solution was then cooled to 25 °C when solid potassium nitrate separated out to leave a saturated solution. Using the information provided in this question, what is the minimum mass of water that must now be added to the mixture of the solution and the solid in order to make this solid potassium nitrate redissolve at 25 °C?

What is the mass of potassium chloride in the saturated solution?

The mass of potassium chloride in a saturated solution will vary depending on the temperature and pressure. At room temperature, the solubility of potassium chloride in water is approximately 35.8 g/100 mL. Therefore, the mass of potassium chloride in a saturated solution can be calculated by considering the volume of the solution.


What causes the equilibrium to shift when a cooled saturated potassium nitrate solution is added to water?

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.


How do you calculate solubility of potassium nitrate?

The solubility of potassium nitrate can be calculated using its solubility product constant (Ksp). The Ksp value for potassium nitrate is determined experimentally and represents the product of the concentrations of the ions in a saturated solution of the compound. By using the Ksp value, you can set up an equilibrium expression and solve for the solubility of potassium nitrate in moles per liter.


What evidence do you have that the equilibrium shifted when saturated potassium nitrate solution was cooled?

The evidence that the equilibrium shifted when a saturated potassium nitrate solution was cooled is the precipitation of potassium nitrate crystals. Cooling the solution causes a decrease in solubility, leading to excess solute (potassium nitrate) to precipitate out of the solution. This indicates that the equilibrium has shifted towards the solid phase as a result of the change in temperature.


What mass of potassium nitrate would be needed to produce a saturated solution of potassium nitrate in 50 grams of water at 313K?

At 313K, the solubility of potassium nitrate in water is approximately 62g/100g of water. To form a saturated solution in 50g of water, you would need roughly 31g of potassium nitrate.


Is potassium chloride saturated in dissolved in 100 g of water it is then cool down for 90C to 60C how many grams of precipitate will be form?

If the solution is saturated at 100°C and then cooled to 60°C, some of the potassium chloride will precipitate out of the solution. The exact amount that will precipitate depends on the solubility of potassium chloride at those temperatures. You would need to consult a solubility table or experimentally determine the solubility at those temperatures to calculate the amount of precipitate formed.


What do you expect to observe when a solution of potassium nitrate saturated at 343 k or 70 c is cooled to room temprature?

Upon cooling the solution of potassium nitrate from 70°C to room temperature, you would expect to observe the formation of crystals as the solubility of potassium nitrate decreases with decreasing temperature. These crystals will form as the excess potassium nitrate in the solution starts to come out of the solution and solidify.


Is water and potassium chloride saturated solution?

Yes, a saturated solution of water and potassium chloride means that the solution contains the maximum amount of potassium chloride that can dissolve in water at a given temperature. Additional potassium chloride added to the solution would not dissolve and would remain as solid at the bottom of the container.


What do you expect to observe when a solution of potassium nitrate saturated at 343 k is cooled at room temperature?

When a saturated solution of potassium nitrate is cooled from 343 K to room temperature, you can expect to observe the precipitation of potassium nitrate crystals. As the temperature decreases, the solubility of potassium nitrate decreases, leading to an excess of solute that cannot remain dissolved. This will result in the formation of solid crystals settling out of the solution. Additionally, the concentration of the remaining solution will remain at saturation until all excess solute has precipitated.


Explain how you would prepare a saturated solution of potassium nitrate in water?

Add potassium nitrate to distilled water while stirring continuously; stop adding potassium nitrate once the chemical becomes saturated and stops dissolving in the water. Filter the solution into an evaporating dish and measure the temperature of the solution. Measure the temperature and carefully heat the solution under low heat. Weigh the potassium nitrate to determine its solubility. You should find that approximately 36 g of potassium nitrate can be dissolved in 100 ml of water at room temperature (25 degrees Celsius). santosh kumar.batchu santoshkumar@gmail.com


What happens when a crystal of potassium nitrate is added to the saturated solution as it is cooled?

Yes, since the solubility of a solid solute in liquid solvent is decreased when the temperature is reduced, then the amount of of solute beyond the solubility limit must crystallize out of solution


A saturated solution potassium nitrate may be made unsaturated by?

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.
