Conclusion: (Identity‚ % error‚ other evidence‚ how to improve) The identity of Unknown A is the compound cobalt(II) chloride hexahydrate (CoCl₂•6H₂O).This is justified by the similarities in color of red-purple crystal like grains‚ which is significant in identifying the product out of the eight suggested identities. Only two had similar characteristics which were CoCl₂•6H₂O and CoSO₄•6H₂O. Before unknown A was heated‚ there was a notable common physical property of the substance being red crystal

Purpose: The purpose of this experiment was to be able to apply our knowledge of chemistry to identify 10 unknown elements that were presented to us. We were allowed to use Bunsen burners‚ hydrochloric acid‚ use PH paper to test if the unknown solution is an acid or a base‚ and precipitate each unknown solution with each other. Procedure / Data / Conclusions: Unknown #1: I found solution 1 to be KI. While doing the precipitate reactions‚ I found that it precipitates only

There are many reasons for identifying an unknown bacterium. The reasons range from medical purposes‚ such as determining if the unknown could cause ailments in living things or knowing what microorganisms are needed to make antibiotics to other purposes such as knowing the exact microorganism has to be used to make certain foods. This experiment was done by applying methods in order to identify an unknown bacterium. An unknown bacterium was handed out by the lab instructor. The methods that
