Drinking Water Contamination Kit Purpose- To identify 5 metals from most active to not active through the process of Single Replacement Reactions. Data/ Conclusion Rank 1 2 3 4 5

Determination of a Hydrate Purpose- To determine the amount of water in the sample and calculate its water of hydration.

Data Compound selected for analysis- mass of crucible-25.13g mass of crucible and hydrated sample-26.63g mass of crucible and dehydrated sample (1st weighing)-26.07g mass of hydrated sample-1.5g mass of crucible and dehydrated sample (2nd weighing)-26.04 mass of crucible and dehydrated sample (if needed)- mass of dehydrated sample-0.91g mass of water evaporated-0.59g

Conclusion After we concluded the procedure, we calculated that the chemical is Copper (II) Sulfate Hexahydrate which is incorrect. i believe that our calculations were slightly off leading to that number that we produce which was 5.737.
