Introduction The purpose of this lab was to explore the properties of an unknown compound. An unknown was given and a cation flame test and anion test was performed to determine the identity of the compound. Once the identity was determined‚ the properties were explored. Experimental To determine the cation of the compound‚ a cation flame test was performed. A bunsen burner was lit until a medium blue flame was burning. The given unknown was scooped onto a nichrome wire loop. The wire was held in the flame

The unknown soda ash from experiment 3 was used‚ to determine the weight for each trial we used the equation of (M of HCl) x (18 ml x 105.99) / (10 x 2 x Na2CO3 ). Which was equal to (0.01472 M) x ((18 mL X 105.99)(10 x 2 X 2.428 % )= 0.6 g. To start we had to rinse the beakers‚ electrode and the stirring bar with diluted water. The sample we needed was weighted to the closest 0.1 mg which we got was 0.3 for the first trial. The sample was transferred to a 250 mL beaker and dissolved in 70 mL of

Having the ability to collect and identify unknown microorganisms is vital in health and medicine. This capability is important for a variety of reasons‚ such as knowing the causative agent of disease‚ knowing if the microorganism obtains any beneficial properties and knowing the correct microorganism to use to create a successful antibiotic. Implementing the experimental methods learned thus far in the microbiology laboratory allowed an unknown bacterium to be identified as a result of this study
