A solution contains 10 g of KNO3 per 100 g of water at 30˚C. Is the solution unsaturated, saturated or supersaturated? Chemistry
Explanation: As you can see, potassium nitrate has s solubility of about 67 g / 100g H2O at 40∘C. This means that at 40∘C, a saturated potassium nitrate solution will contain 67 g of dissolved salt for every 10 0g of water.You know that at this temperature, your solution contains 35 g of potassium nitrate in 100 g of water. This solution will be unsaturated because it contains less potassium nitrate than the maximum amount that can be dissolved.In order to make a saturated solution, you must get the total mass of potassium nitrate to 67 g, which means that you must addmass of KNO3ato be added=67 g−35 g=∣∣∣∣¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯aa32 gaa∣∣−−−−−−−−Reply
