Approximately 73.2 grams of copper sulphate can be dissolved in 50 grams of water at 60 degrees Celsius. This is the maximum amount of copper sulphate that the water can hold in a saturated solution at that temperature.
Approximately 204 grams of sugar can be dissolved in 250 g of water at 20 degrees Celsius. This is the saturation point for sugar dissolving in water at this temperature.
The salt will dissolve in the water to create a salt solution. At 30 degrees Celsius, the solubility of salt in water is high, so it should fully dissolve. The resulting solution will have a higher density than pure water due to the dissolved salt.
Approximately 39 grams of sodium chloride can be dissolved in 100 grams of water at 95 degrees Celsius.
The amount of sodium chloride that would dissolve in 2 L of water at 20 degrees Celsius depends on if the water is moving. It would dissolve faster in moving water than still sitting water.
Approximately 73.2 grams of copper sulphate can be dissolved in 50 grams of water at 60 degrees Celsius. This is the maximum amount of copper sulphate that the water can hold in a saturated solution at that temperature.
Approximately 200 grams of KNO3 can be dissolved in 100 ml of water at 50 degrees Celsius.
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.

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.
The enthalpy of dissolution is 3,87 kJ/mol for NaCl.
No, pure water boils at 100 degrees Celsius at normal temperature and pressure. The fact that the water boiled at 102 degrees Celsius indicates that it may not be pure and could contain impurities or dissolved substances.
The resulting mixture is a homogeneous solution. At 25 degrees Celsius, the KCl would dissolve in water to form a clear, colorless solution. The solute (KCl) is evenly distributed in the solvent (water) at the molecular level.
