Question

The results of the lab are attached. Need help with the following question:

3. Experience teaches us that most solids are more soluble in warm water than cold water. Does the solubility of Mg(OH)2 fit this pattern. 

S. Draw the solution and as much of the precipitate as possible from well B3 into one of the
Beral pipets. Carefully expel the solution back into well B3 in order to mix it. Now draw the
mixture from wells B3 and B4 into the Beral pipets and transfer the mixtures to two test
tubes. Place the test tube containing the mixture from well B3 in the hot water bath and the
test tube containing the mixture from well B4 in the ice bath. Allow each test tube to remair
in its water bath for 3 or 4 minutes. Swirl the test tubes to speed the heating and cooling
processes. Record the observed color change in the two test tubes.
