The first test conducted on unknown bacteria 32 was the Gram stain. From this stain‚ unknown 32 was found to be a Gram-positive cocci. This test eliminated all possible Gram-negative bacteria‚ Gram-positive rods and Gram-positive spirillium. Next‚ the endospore test determined whether or not the Gram-positive bacteria contained endospores. With the use of malachite green‚ steam‚ and safranin it was found that unknown bacteria 32 did not contain endospores. This eliminated Gram-positive cocci Sporosarcina

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
