Measure the temperature of the water with a thermometer
Calculate the mass of salt using mass of salt water in beaker - mass of water in beaker
Measure the mass of the salt solution with a mass balance
Add the water to the beaker
Add potassium chloride until no more will dissolve
First Measure 100 cm3 of water using a measuring cylinder
Finally Repeat the experiment using different temperatures of water.
Measure the mass of the water and beaker with a mass balance
Mass of KCl that dissolves in 100g of water at 0oC =
Mass of NaCl that dissolves in 100g of water at 0oC =
Temperature at which the solubility of NaCl and KCl are equal =
As the temperature increases the solubility of KCl
As the temperature increases the solubility of NaCl
At 10oC the solubility of NaCl is
Magnesium oxide (MgO)
Carbon monoxide (CO)
Water (H2O)
