Heat the solution above 50°C until all of the solid dissolves. With beaker tongs, remove the beaker from the hot plate and set it on the bench top, out of the way. Place an applicator stick, or suspend a string, into the solution and allow the solution to cool. Continue with the next part of this experiment and return to this part after the solution cools to room temperature. 

When you see the colour change, stop heating the beaker. Turn off or unplug the hot plate. Remove the beaker with the beaker tongs. Allow the beaker and crystals to cool on a hot pad.

Turn off the hot plate or burner, and allow the beaker to cool. Use beaker tongs to move the beaker, as shown in Figure E. Measure the mass of beaker... 

The next day, use beaker tongs to remove beaker 1 with the filter paper and KNO3 from the drying oven. Allow the beaker to cool. Measure the mass using the same balance you used to measure the mass of the empty beaker. Record the new mass in your data table. Be sure to use beaker tongs. Remember that hot glassware does not always look hot. 

Using beaker tongs, remove your sample from the drying oven, and allow it to cool. Measure and record the mass of the beaker with paper towel, filter paper, and precipitate to the nearest 0.01 g. 

Half fill a 250-mL beaker with water and set it on a hot plate. Put a thermometer in the water and monitor its temperature until it reaches about 60°C. Remove the beaker from the hot plate with beaker tongs and set it on the lab table.
