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 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 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.
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.
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.

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 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.
What bond is break in order to form potassium nitrate solution?
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.
How will you prepare a supersaturated solution of potassium nitrate in water?
To prepare a supersaturated solution of potassium nitrate in water, you would first dissolve an excess amount of potassium nitrate in hot water, stirring continuously until no more of the salt can dissolve. Then, let the solution cool slowly without disturbing it, which will allow the excess salt to form crystals at the bottom, creating a supersaturated solution above it.
What is the conductivity of potassium nitrate?
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.
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.
What is the physical appearance of the potassium nitrate solution?
The state of matter for potassium iodide is a purplish solid:)
