How does a decrease in temperature from 40 degrees celsius to 20 degrees celsius affect the solubility of NH3 and KCl?
A decrease in temperature generally decreases the solubility of gases like NH3, making it less soluble at 20 degrees Celsius compared to 40 degrees Celsius. On the other hand, for solids like KCl, a decrease in temperature typically increases solubility, leading to higher solubility at 20 degrees Celsius compared to 40 degrees Celsius.
What is the solubility of urea in water at 25 degrees Celsius?
the solubility of urea solution at 20 degrees celsius is 107.9 g / 100 ml
What is the solubility of caffeine in water at 25 degrees Celsius?
The solubility of caffeine in water at 25 degrees Celsius is approximately 20 mg/mL.
How many grams of KCl remain in solution at 20 degrees celsius when a solution containing 80g of KCl in 200g of water at 50 degrees Celsius is cooled to 20 degrees Celsius?
To find the amount of KCl that remains in solution at 20 degrees Celsius, you can use the principle of solubility. Calculate the maximum amount of KCl that can dissolve in 200g of water at 20 degrees Celsius using a solubility chart. Once you have this value, compare it to the initial 80g of KCl to determine how much remains in solution after cooling.
What is the solubility of ammonium chloride per 100 g of water at 20 degrees Celsius?
60.5
What is the solubility of silver nitrate if 11.1 g can dissolve in 5.0 g of water at 20 degrees Celsius?
The solubility of silver nitrate in water at 20 degrees Celsius is 11.1 g/5.0 g or 2.22 g/g. This means that for every gram of water, 2.22 grams of silver nitrate can dissolve at this temperature.
