Transfer a small amount of solid copper (II) sulfate pentahydrate, CUSO4-5H;O, that just fills the bottom of a clean, dry 150-mm (medium size) test tube. 2. Using a test tube holder, grasp the test tube containing the hydrate and heat over a Bunsen burner flame while holding the test tube at a 45° angle. 3. While heating, closely observe the solid and the inside wall of the test tube. Record your observations. 4. When the solid residue seems to be completely dehydrated, allow the test tube to cool completely. Then, add a few drops of laboratory water to Record your observations. solid in the test tube.…

What will be the probable effect if you kept the crucible completely covered during the entire heating and cooling processes? Would your calculated percent water in the hydrate be high, low, or unaffected? Explain. 3. If 2.752 g sample of Ca(NO:); XH;O is heated to constant mass, the residue weighs 1.941 g. Determine the value of x and the formula of the hydrate.
