1. The problem statement, all variables and given/known data Not much background information is needed. Lead (II) iodide is dissolved into deionized water, and the temperature of the solution is manipulated in order to explore the relationship between temperature and the solubility of the solution. To allow the solution to completely dissolve, it is placed inside an Erlenmeyer flask and heated to 100°C. "When the Erlenmeyer flask is brought to 100°C and the solid settles, the hot saturated solution is transferred to a test tube using a warm pipette. Why must the pipette be warm in completing the transfer?" 2. Relevant equations N/A 3. The attempt at a solution "The pipette is warm to ensure that the solubility of the lead (II) iodide is not affected by changes in temperatures caused during the transfer to the test tube and that the volume of solution measured is accurate. If the pipette is cool, a certain amount of precipitate may be left inside the pipette after the transfer, affecting the measured final results of the experiment. Also, using a cool pipette may pose a safety hazard, as its glass could crack due to a sudden shift in temperature when placed into a 100°C solution." Is this statement correct, or am I missing certain details that are common practice in a laboratory environment? Any help is greatly appreciated. :) Thank you, Eric.
