Name: Date: Block: Effect of Heat on Solubility

As any cook knows, salt dissolves in water. But does the temperature of the water effect how much salt can be dissolved?

Hypothesize (Explain what you think):

Procedure:
 * 1) Gather the following materials: scale, hot plate, 500ml beaker, Petri dish, salt, ice water, tap water, Vernier probe, thermometer probe, stirring rod
 * 2) Turn on the scale and place the Petri dish onto it. Do not zero the scale.
 * 3) Measure out 10 grams of salt (Sodium Chloride – NaCl)
 * 4) Pour 100ml of iced water into the beaker.
 * 5) Measure and Record Temperature.  0C
 * 6) Slowly add salt to the iced water continuously stirring until no more salt will dissolve into the water.
 * 7) Measure and Record mass of remaining salt in Petri Dish.
 * 8) Calculate mass of salt dissolved into iced water. (Show Your Work Here)


 * 1) Clean beaker with soap and water.
 * 2) Fill beaker with 100 ml. of tap water.
 * 3) Refill Petri dish to 10 grams of salt
 * 4) Measure and record temperature of tap water.  0C
 * 5) Slowly add salt to tap water continuously stirring until no more salt will dissolve into the water.
 * 6) Measure and record mass of remaining salt in Petri dish.
 * 7) Calculate mass of salt dissolved into iced water. (Show Your Work Here)
