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
You would have a saturated solution because at that temperature and concentration, the amount of sodium chloride being dissolved is in equilibrium with the amount that can be dissolved. Any more added would exceed its solubility.
The pH value of potassium sulfate, K2SO4, is neutral, around 7. This is because potassium sulfate dissociates in water to release potassium ions (K+) and sulfate ions (SO4^2-) which do not significantly affect the pH of the solution.
potassium has melted by time it reaches 20 degrees.
At 60 degrees Celsius, the solubility of potassium chlorate (KClO₃) in water is approximately 7.2 grams per 100 grams of water. To create a saturated solution in 200 grams of water, you would need about 14.4 grams of potassium chlorate (7.2 g/100 g water x 200 g water = 14.4 g KClO₃). Thus, 14.4 grams of potassium chlorate would be required for saturation at this temperature.
If 50 grams of water saturated with potassium chlorate at 23 degrees Celsius is slowly evaporated to dryness, approximately 6.5 grams of the dry salt (potassium chlorate) would be recovered. This is based on the solubility of potassium chlorate in water at that temperature.

Well, isn't that just a happy little question! When you cool a saturated solution of potassium nitrate from 70 degrees Celsius to room temperature, you can expect to see some of the potassium nitrate start to come out of the solution and form crystals. It's like nature's way of showing us how beautiful and orderly things can be when they slow down and cool off. Just like painting a serene winter scene, the crystals will slowly appear and bring a sense of peace and tranquility to the solution.
The percent by weight of NaCl in a saturated solution at 50 degrees Celsius is approximately 26.3%. This means that in every 100 grams of the solution, 26.3 grams is NaCl.
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.
One solution that will not freeze at 0 degrees Celsius is a saturated salt solution, such as a solution of sodium chloride (table salt) in water. The addition of salt lowers the freezing point of water, preventing it from freezing at 0 degrees Celsius.
This would be considered a saturated solution if all 25g of KCl are completely dissolved in the 100g of water at 30 degrees Celsius.
To prepare a saturated solution of copper sulfate at 20 degrees Celsius, you would need to dissolve approximately 203 grams of copper sulfate in 400 grams of water. This is based on the solubility of copper sulfate in water at that temperature.
The melting point of potassium bromide is 734 degrees Celsius.
You would have a saturated solution because at that temperature and concentration, the amount of sodium chloride being dissolved is in equilibrium with the amount that can be dissolved. Any more added would exceed its solubility.
