A student is evaluating the solubility potassium (KClO3) at various temperatures. She dissolves 2.50 g of KCLO3 in a total volume of 7.5 mL of water.
a. Calculate the concentration of KClO3 in this solution.
b. The student heats the solution up to 80 degrees Celsius, the removes the test tube containing the salt solution from the hot water bath. At what temperature would you expect to see the formation of salt crystals in the solution?
c. If the solution is allowed to cool to 30 degrees Celsius, what percentage of the salt remains dissolved in solution?

0.50 g of potassium nitrate (KNO3) was added to a test tube holding 5 mL of distilled water. A temperature probe was placed in the test tube to record any change in temperature during the reaction. The baseline temperature of the water before adding the KNO3 was 23.2 degrees Celsius. After the KNO3 was added to the water the temperature of the solution dropped to 18.1 degrees Celsius. 1) Write an equation for the reaction above. Make sure it has...

Principles of Inorganic Chemistry! Week 5 Effect of Temperature on Solubility of a Salt In this experiment, you will study the effect of changing temperature on the amount of solute that will dissolve in a given amount of water. Water solubility is an important physical property in chemistry, and is often expressed as the mass of solute that dissolves in 100 g of water at a certain temperature. In this experiment, you will completely dissolve different quantities of potassium nitrate,...

solubility curve of salts
Solubility Curve of Salts ( Extra Credit: Maximum of 5 pts.) The solubility curve for solutes describes at what the temperature its solution will be saturated (maximum solubility). Beyond that amount, the salt will start to crystallize. The solubility of sodium chloride and potassium chloride in water at different temperatures is given in the table below: Naci КСІ Temp (C) Solubility (g/100g H2O) Temp (C) Solubility (g/100g H,O) 0 35.65 28 10 35.72 35.89 20 30...
