Why 100ml solution of KNO3 can not hold more than 37 gm of KNO3 in dissolved state?
potassium nitrate solubility at room temperature 25 degree celsius is about 383 g /L.
if we want per 100 ml then .... 383 g / 1000ml ....we know that
1 L=1000ml
now for per 100 ml it becomes
38.3g/100ml
now we can see that KNO3 solubility in 100 ml solution is 38.3 g.....so we can say that
100 ml solution of KNO3 can not hold more than 37 g or 38.3 g of KNO3 in dissolved state.
What else can I help you with?
An aqueous KNO3 solution is made using 89.9g of KNO3 diluted to a total solution volume of 1.35L?
The molarity of the KNO3 solution is 0.544 M. This is calculated by dividing the moles of KNO3 (1.1 mol) by the total solution volume in liters.
How do you separate KNO3 from aqueous sol of KNO3?
You can separate KNO3 from its aqueous solution by a process called evaporation. Simply heat the solution to evaporate the water, leaving behind solid KNO3. This method exploits the fact that KNO3 has a much higher boiling point compared to water.
What is the molarity of a solution that contains 5.10 mol KNO3 in 4.47 kg?
First, convert the mass of KNO3 from kg to g (1 kg = 1000 g). 4.47 kg = 4470 g. Next, calculate the molarity using the formula Molarity = moles of solute / volume of solution in liters. Given that the moles of KNO3 is 5.10 mol and the mass of KNO3 is 4470 g, you need to convert the mass to volume using the density of KNO3 to determine the volume of solution in liters.
An ionic compound whose aqueous solution conducts an electric current?
When dissolved in water, ionic compounds dissociate into ions, allowing them to conduct electricity. The presence of free ions in the solution enables the flow of electric current. Examples of such compounds include sodium chloride (NaCl) and potassium nitrate (KNO3).
How many grams of potassium nitrate (KNO3) will settle out when a saturated solution made in 100 grams of water is cooled from 70 and degC to 50 and degC?
To determine how many grams of potassium nitrate (KNO3) will settle out when cooling a saturated solution from 70°C to 50°C, you would need the solubility data for KNO3 at both temperatures. Typically, KNO3 is more soluble at higher temperatures, so as the solution cools, some KNO3 will precipitate out. If, for example, the solubility at 70°C is around 120 g/100 g water and at 50°C it's about 85 g/100 g water, then approximately 35 grams of KNO3 would settle out upon cooling. However, you would need the exact solubility values for an accurate calculation.
Why cannot 100ml of KNO3 solution hold more than 37gm of KNO3 in a dissolved state?
The solubility of KNO3 in water is limited by the solubility product constant, which is the equilibrium constant for dissolution of the salt in water. If more than 37g of KNO3 is added to 100ml of solution, it exceeds the maximum amount that can be dissolved at that temperature, leading to the excess forming a separate solid phase.
Why 100 ml of kN03 can not hold more than 37 grams of kN03 in dissolved state?
The solubility of KNO3 in water is limited by its equilibrium solubility product. Once this limit is reached, no more KNO3 can dissolve at that temperature. In this case, the solubility of KNO3 at 20°C in water is about 37 grams per 100 ml of water, which means the solution is saturated and cannot hold more KNO3 in a dissolved state without exceeding that limit.
The vapour pressure of water at 25degrees is 3.14kPa When 0.050 mol of KNO3 is dissolved in 100ml of water at 25 degrees the vapour pressure is lowered by?

Why test tube becomes cold when KNO3 is dissolved in water?
When KNO3 is dissolved in water, it absorbs heat from the surroundings, causing the temperature of the solution to decrease. This is an endothermic process, meaning it requires energy, which it takes from the surroundings. As a result, the test tube and the water around it feel cold as heat is transferred to the KNO3 solution.
What is the formula for potassium nitrate dissolved in water?
The chemical formula for potassium nitrate dissolved in water is KNO3(aq), which shows that potassium nitrate has dissociated into its constituent ions (K+ and NO3-) in the water solution.
An aqueous KNO3 solution is made using 89.9g of KNO3 diluted to a total solution volume of 1.35L?
The molarity of the KNO3 solution is 0.544 M. This is calculated by dividing the moles of KNO3 (1.1 mol) by the total solution volume in liters.
How do you separate KNO3 from aqueous sol of KNO3?
You can separate KNO3 from its aqueous solution by a process called evaporation. Simply heat the solution to evaporate the water, leaving behind solid KNO3. This method exploits the fact that KNO3 has a much higher boiling point compared to water.
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.
How many total moles of KNO3 must be dissolved in water to make 1.5 liters of a 2.0 M current?
To find the total moles of KNO3 needed, use the formula: moles = molarity x volume (in liters). So, moles = 2.0 mol/L x 1.5 L = 3.0 moles of KNO3. Therefore, 3.0 moles of KNO3 need to be dissolved in water to make 1.5 liters of a 2.0 M solution.
Is KNO3 it basic or acidic?
Potassium nitrate is a neutral salt, t is neither acidic nor alkaline.
How many grams of kno3 can be dissolved at 50 degrees Celsius?
Approximately 200 grams of KNO3 can be dissolved in 100 ml of water at 50 degrees Celsius.
Will 110 g of KNO3 in 100 g of water at 40 degrees Celsius be saturated or unsaturated?
To determine if a solution is saturated or unsaturated, we need to compare the actual solubility of the solute at the given temperature to the amount of solute dissolved in the solution. At 40 degrees Celsius, the solubility of KNO3 in water is approximately 80 g/100 g water. Since you have 110 g of KNO3 in 100 g of water, the solution is supersaturated because it contains more solute than it can normally hold at that temperature.
