For the first reaction a sample of the copper chloride hydrate Cu x Cl y zH 2 0 is placed in a ceramic crucible and is gently heated with a Bunsen burner to drive away the waters of hydration and form the the anhydrous copper chloride compound Cu x Cl y The crystalline hydrate is stirred slowly with a metal spatula during this step to promote thorough heating and full chemical conversion of the sample
[email protected]And everyone lived happily ever after Conclusion Conclusion We concluded that we didnt get the right empirical formula because we did not measure our substances correctly This could be due to the fact that we didnt directly measure the the amount of chlorine We subtracted
