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.


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

Well, isn't that just a happy little question! When you cool a saturated solution of potassium nitrate from 70 degrees Celsius to room temperature, you can expect to see some of the potassium nitrate start to come out of the solution and form crystals. It's like nature's way of showing us how beautiful and orderly things can be when they slow down and cool off. Just like painting a serene winter scene, the crystals will slowly appear and bring a sense of peace and tranquility to the solution.


What is aqueous potassium nitrate?

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.


Can you give me a conclusion on the solubility curve of potassium nitrate?

The solubility curve of potassium nitrate shows that its solubility increases with temperature. This means that more potassium nitrate can dissolve in water as the temperature rises. Additionally, the curve can be used to predict how much potassium nitrate will dissolve at a certain temperature.


What is the answer of what is the weight percent of potassium nitrate in a solution that is made by dissolving 30.0 g of potassium nitrate in 90.0 g of water?

To find the weight percent of potassium nitrate in the solution, first calculate the total mass of the solution, which is the sum of the mass of potassium nitrate and the mass of water: 30.0 g + 90.0 g = 120.0 g. Next, use the formula for weight percent: (mass of solute / total mass of solution) × 100%. Thus, the weight percent of potassium nitrate is (30.0 g / 120.0 g) × 100% = 25.0%.

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.


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.

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.


How many grams of crystals will b formed if a saturdayed potassium nitrate solution is cooled from 60 to 30?

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.


How we obtain pure potassium nitrate which is free of soil?

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.


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 to crystallize potassium nitrate from its aqueous solution?

To crystallize potassium nitrate from its aqueous solution, you can gradually heat the solution to evaporate the water until crystals start to form. Then, allow the solution to cool slowly to encourage crystal growth. Finally, filter the solution to separate the crystals from the remaining liquid.


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.


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

What gas evolved when potassium nitrate crystals are heated with concentrated sulphuric acid?

When potassium nitrate crystals are heated with concentrated sulphuric acid, nitric oxide gas (NO) is evolved. This is a result of the oxidation of nitrate ions in potassium nitrate by the sulphuric acid.
