In our lab‚ we were given the task of burning seven different salts and taking notes of what we observed. The different salts included Potassium chloride‚ Calcium chloride‚ Strontium chloride‚ Lithium chloride‚ Copper II chloride‚ Sodium Chloride‚ and Barium Chloride. Burning a pinch of each salt separately by holding a nichrome wire over a Bunsen burner‚ we found that each salt emitted a different color of light. For example‚ Potassium Chloride burnt a bright pink flame when burned‚ while Calcium

In this experiment‚ you will analyze a known solution that contains the entire Group I cations—silver‚ lead‚ and mercury (I)—and an unknown solution to determine which ions are present and which are absent. II. DISCUSSION: The chlorides of Pb2+‚ Hg22+ and Ag+ are all insoluble in cold water. They can be removed as a group from solution by the addition of HCl. The reactions that occur are simple precipitations and can be represented

If the water was warmer‚ this may have sped the diffusion process because the molecules would have been moving faster. If the water was freezing‚ this may have slowed the diffusion process because the molecules may have been moving slower. Part B: Title: The effect of salt concentration on osmosis in potato.

Lab Practical One Report Unknown Bacteria Staining Gram Acid Fast Spore The first practical for microbiology was staining of an unknown bacteria. Professor Goode provided an unlabeled bacteria in which each individual were to conduct gram‚ acid fast‚ and spore staining tests from memory. When the gram staining test was conducted a positive results was obtained. When views on oil bacteria appeared purple and rod-like. I noted this result and looked at the lab key to see what the results narrowed
