Water DOES freeze when potassium nitrate is in it, it just doesn't do so as easily.
Any solute will lower the freezing point of a solvent by a characteristic amount; for water it's 1.853 K kg/mol (that's Kelvins, kilograms of water, and moles of solute species; potassium nitrate is ionic and very soluble, so one mole of potassium nitrate will lower the freezing point of a kilogram of water by 3.7 Kelvins).
This and similar effects are called "colligative properties", and the simplistic explanation is that the solute disrupts the ice crystal lattice ... essentially, it "gets in the way" of the water freezing.
What else can I help you with?
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.
Which is the largest mass of potassium nitrate which can be dissolved in 50 g of water at 60 oC?
Potassium nitrate is very soluble in water.The largest mass of potassium nitrate which can be dissolved in 50 g of water at 60 oC is 53 g.
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 mass of water is needed to dissolve potassium nitrate at 15 degrees Celsius?
The solubility of potassium nitrate at 15 0C is 47 g/100 g water.
Does potassium nitrate dissolve in any alcohol?
Potassium nitrate has limited solubility in alcohol. It dissolves better in water due to its polar nature.
Is potassium nitrate has solibility in water or not?
Potassium nitrate is quite soluble in water, as are all nitrate salts.
What product will you get if you add water in potassium nitrate?
Since all nitrates are soluble in water, you would get a mixture of Potassium ions and Nitrate ions floating around in water.
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.
Will Potassium nitrate dissolves in water?
Yes, Potassium nitrate (KNO3) is highly soluble in water.
Reaction equation of potassium nitrate with water?
The reaction equation for potassium nitrate (KNO3) with water (H2O) is: KNO3 (s) + H2O (l) -> K+ (aq) + NO3- (aq) + H2O. This reaction is a dissolution reaction, where the solid potassium nitrate dissolves in water to form aqueous potassium ions, nitrate ions, and water molecules.
In which is KNO3 soluble benzene hexane or water?
Potassium nitrate is soluble in water, as it is an ionic solid. When dissolved in water, potassium nitrate will form an aqueous solution of potassium and nitrate ions.
Is Potassium nitrate endothermic or exothermic?
The dissolution of potassium nitrate in water is an endothermic process.
What is the chemical formula of the salt produced by the neutralization of potassium hydroxide with nitric acid?
Potassium Nitrate+Water HNO3 (aq)+KOH (aq)-->KNO3 (aq)+H2O (l)
What substance is more likely to dissolve in water salt or potassium nitrate?
Potassium nitrate is more soluble.
Is potassium nitrate soluble in methanol?
Yes, potassium nitrate is soluble in methanol. Potassium nitrate is generally soluble in polar solvents like water and methanol.
What is the molecular formula for potassium nitrate?
The chemical symbol for potassium nitrate is potassium. "KNO3"
How does temperature affect the amount of potassium nitrate that will dissolve in water?
Generally, as temperature increases, the solubility of potassium nitrate in water also increases. This is because higher temperatures provide more energy to break the bonds between the potassium nitrate molecules and the water molecules, allowing more potassium nitrate to dissolve.
