How many grams of KNO3 will dissolve in 100g of water?
So, you know that potassium nitrate, KNO3 , has a solubility of 155 g per 100 g of water at 75∘C and of 38.0 g at 25∘C .
How many grams of KNO3 can be dissolved in 100g 40 water?
As you can see, potassium nitrate has s solubility of about 67 g / 100g H2O at 40∘C .
What happens to a solution of KNO 3 that is saturated at 50 ℃ when it is cooled quickly to10 ℃?
So, you know that you’re dissolving 50 g of potassium nitrate, KNO3 , a soluble salt, in 50 mL of water at a temperature of 60∘C . Since you have less potassium nitrate than that, your solution will be unsaturated. When you cool the solution to 10∘C , potassium nitrate’s solubility decreases significantly.
When 30 grams of potassium nitrate KNO3 is dissolved in 100 grams of water at 20 degrees Celsius The solution can be described by?
The correct answer is a. The solution is not saturated because the solubility of potassium nitrate at this temperature is 316 grams…
How many grams of KNO3 can dissolve in 100g of water at 50c?
(d) Initially there is 100 g of potassium nitrate in solution, at 50 °C the solubility is 84 g/100g (original data or graph), so 16 g will have crystallised out.
What is the solubility of potassium nitrate in 100 grams of water at 60 C?
Task 1: Producing a graph to represent solubility data
| Potassium nitrate (KNO3) | Sodium nitrate (NaNO3) | |
|---|---|---|
| Temp. °C | g / 100 g water | g / 100 g water |
| 40 | 63 | 105 |
| 50 | 84 | 114 |
| 60 | 108 | 124 |
What is the saturated solution?
Definition of ‘saturated solution’ A saturated solution is a solution in which there is so much solute that if there was any more, it would not dissolve. When water, or any solvent, has dissolved as much of any substance as it can, it is a saturated solution.
