At 50 degrees on the solubility curve KClO3 should be saturated at 21g per 100g of water. Knowing this the one liter given to you in the question can be written as 1,000 ml or 1,000g of H2O since the density of water is 1g/ml. Set up an equation: 21g KCLO3/ 100g Water = x/ 1000g water
x=210g
Answer: 210g KClO3
Aproximately 4 grams of potassium chlorate will dissolve in 50 g of water at 20 degrees celsius.
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
Ammonium Nitrate! Fo sho doe.
Calcium at 860 degrees celsius potassium melts at a mere 65 degrees celsius
The pKa of HSO4- (the second pKa of H2SO4) is 1.92. The Ka is thus 0.0120

how will you use the particle theory to explain why a saturated solution at 30 degreecelsius can become dilute at 70degree Celsius
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.
