Question

5. How the observed experimental error influence on the 'Calculated Percent of Water'. Explain whether % of water calculated is going to be High or low in each of the following cases. (Hint: use equation 4.2) a) Some solid material fell out of the crucible during the heating. HIGH / LOW? Why? b) The hydrate was not heated to constant mass. HIGH / LOW? Why? c) The crucible and anhydrous solid were carried in wet hands (rather than using tongs) over to the balance for the final weighing. HIGH / LOW? Why?
