In this experiment‚ gravimetric analysis will be used to determine the unknown metal carbonate. Gravimetric analysis. Gravimetric analysis is a method where an ion being analyzed can be classified through their mass (Yoder 2018). Due to the fact that carbonates can be hygroscopic‚ which means it would be able to absorb water from water vapor‚ extra precautions have to be taken place to be able to get an accurate mass (Helmenstine 2017). This can be done by using a drying oven and a desiccator. A

involves two oxidation-reduction reactions to calculate the oxidizing capacity of a sample of unknown bleach. In order to determine the volume of Na2S2O3 added‚ students will conduct a titration of bleach with thiosulfate with addition of a starch indicator to find the end point of the titration. Moreover‚ the oxidizing capacity of bleach is calculated with the percentage by mass of NaOCl in the unknown bleach sample. The overall chemical reaction throughout the experiment will be balanced with the

Assisting Sport for Disabilities Disability Identification Due to the Paralympics being held in London in 2012 the British public were treated to a media extravaganza. With the fantastic live coverage that was available‚ we not only got to witness a fantastic spectacle where competitors would compete to a very high level‚ we also got to see behind the scenes footage of how the athletes live with their personal disability in their day to day lives. These high profile athletes brought awareness

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

Alyse Rose Microbiology Lab Bacterial Unknown March 25‚ 2013 Bacterial Unknown Report Each student was given an unknown bacteria to figure out. I was given the unknown bacteria S38. Everybody is supposed to do all sorts of test to identify the bacteria. The first thing I did was smear my bacteria on a liquid medium. I then proceeded to incubate the medium for 24-48 hours. 1. GRAM STAIN The next step I took in finding my unknown bacteria was to gram stain it. This is used to differentiate

Unknown Anomaly In the not so distant future‚ humanity has expanded its reach to distant planets‚ seeking refuge from Earth’s depleted resources. Among these colonies is Terra Nova‚ a swarming settlement on the outskirts of known space. Captain Brian Laurier leads the exploration vessel‚ the Mercury X‚ on a mission to scout new planetary systems for colonization. During a routine mission‚ the Mercury X encounters a peculiar anomaly—a rift in space-time that defies all known laws of physics. Its

Chemical T ests for Unknowns Chemical tests have been developed as a means of identifying what functional groups are present in an unknown compound. Since IR and NMR spectroscopy has been developed‚ they are no longer critical to unknown analysis‚ but they can still be useful for confirming what you have determined by spectroscopy. Some of them look cool too! In order for a chemical reaction to work as a chemical test‚ it must 1) create a visible result (a color change‚ a precipitate‚ etc)
