What is the melting point of KCL?
K2CO3 is the molecular formula for potassium carbonate. K2CO3 has a melting point of 1164 degrees Kelvin and is 138.21 grams per mole.
Which potassium salt is the least soluble at 40 C and at 80 C KBr or KCl?
At 40°C, KBr is less soluble than KCl. At 80°C, the trend may reverse, with KCl possibly being less soluble than KBr. The solubility of salts typically increases with temperature, so KBr may be the least soluble at both 40°C and 80°C.
How many grams of KCl can dissolve in 100 g of water at 80C?
Approximately 42 grams of KCl can dissolve in 100 grams of water at 80°C.
Why is the solubility of salts in the water normally given only for temperatures between 0 Celsius and 100 Celsius?
Solubility values are typically provided for the 0-100°C range because water's properties change significantly outside this range. At temperatures beyond 100°C, water transitions to steam, altering its solvent properties. Below 0°C, water forms ice, which can affect solubility dynamics. This range is thus a standard reference point for solubility measurements.
What is the solubility of silver nitrate if only 11.1 g can dissolve in 5.0 g of water at 20 c?
The solubility of silver nitrate in water at 20°C would be 11.1 g/5.0 g = 2.22 g/g.
What is the solubility of NaCl at 20 degrees C in 100 grams of water?
The solubility of NaCl at 20 degrees C in water is approximately 36 grams per 100 grams of water.

If you want to dissolve 91.6 g of KCl in 200 g of water what temperature should the water be?
To dissolve 91.6 g of KCl in 200 g of water, the water should ideally be at a temperature around 60°C. KCl has a moderate solubility in water, and heating the water increases the solubility of many salts, including KCl. However, the exact temperature can vary depending on the desired solubility and the specific conditions. It’s recommended to check solubility tables for precise values at different temperatures.
What is solubility of pottasium chloride in water?
Potassium chloride (KCl) is highly soluble in water, with a solubility of approximately 34 grams per 100 milliliters at room temperature (around 20°C). This means that a significant amount of KCl can dissolve in water, making it useful in various applications, including food seasoning and as a potassium supplement. The solubility may vary slightly with temperature, generally increasing as the temperature rises.

What is the solubility of cyclohexane in water?
Solubility in water, 8.7 g/100 ml at 20°C
What is the solubility of silver nitrate if only 11.1 g can dissolve in 5.0 g of water at 20 c?
The solubility of silver nitrate in water at 20°C would be 11.1 g/5.0 g = 2.22 g/g.
What mass of KCl would be needed to form a saturated solution if the KCl was dissolved in 200 g of water at 80 C?
The solubility of KCl in water at 80°C is approximately 380 g/L. To form a saturated solution, you would need to dissolve 380 g of KCl in 1 L (1000 g) of water. Since you are using 200 g of water, you would need 76 g of KCl to form a saturated solution.
If the solubility of sucrose in 100ml of H2O is 204 g at 20 degrees C and 260 g at 50 degrees C label as saturated unsaturated or supersaturated Adding 200 g to 100 ml of H2O at 20 degrees C?
If 204 g of sucrose is already dissolved in 100 ml of water at 20 degrees C, and you add an additional 200 g of sucrose, it will exceed the solubility limit of 204 g at that temperature, resulting in a supersaturated solution. This means that the solution will become unstable and the excess sucrose is likely to crystallize out of the solution.
