Want this question answered?
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.
I suppose that this temperature is approx. 5 oC.
Yes
Technically, yes. Potassium nitrate is a potassium atom attached to the nitrate ion.
Potassium nitrate is soluble in water, the solution is filtered and evaporated.Oleic acid is soluble in ethanol and separated by filtration and evaporation of the alcohol.
At a given temperature a solution is saturated when the the solute become insoluble.
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.
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
By heating it.
By farting. how many gms potassium nitrate and how many ml water
Its because Potassium Nitrate is a spectator in most electrochemical cells. Spetator as in it does not react with the other species in the solution that undergo oxidation or reduction.
More than 45,5 g KNO3.
The solution forms bigger crystals that have pointed ends.
The solution become saturated ove 124,6 g potassium nitrate.
KNO3 140 g/100 g of water is a saturated solution at about 70 to 75 oC. The solubility change with temperature and it need to be stated for reference temperature. For standard room temperature, KNO3 is saturated at 38.3 g/ 100 g water.
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?
Lead nitrate + potassium sulfate ---> Lead sulfate + Potassium nitrate
