Post Lab Questions 1. In reality the moles of water associated per mole of ionic compound is whole number. If the hydrate in part B was magnesium sulfate, write out a molecular formulahat represents the hydrated version. 2. Take a look at the data for part B. Use the % RSD to determine if the experiment was carried out in aq precise manner. Explain your answer in 1 to 2 sentences. 3. Name the following hydrates a. NiCl2-6H20 b. Ba(OH)2-8H20 c. MgSO4-7H2O 4. Provide a formula for the following hydrates, using the same formatting given in lecture and text book for ionic compounds: a. Copper (III) nitrate trihydrate b. Barium chloride dihydrate c. Cobalt (II) sulfate heptahydrate С. 5. List two sources of error for this experimental procedure shown in the video with the blue solid. Think about how the procedure was designed and what about it could have either led to loss of solid or incomplete dehydration. Remember recording measurements incorrectly is never valid source of error.
