Determine the concentration of an unknown copper (II) sulfate solution by using colorimeter Introduction: The concentration of the solution also alterations the proximity of the solution. For example‚ the more focused concentration will frame to be denser than more weakened concentration of copper (ii) sulfate. This implies there is a connection between the concentration of an solution and its absorbance. Along these lines‚ this test is set up to discover the kind of connection between the concentration

Lab # 11 – Acid - Base Titration Introduction: The purpose of this lab is to determine the molarity (M) of an unknown HCl solution. A NaOH solution will be made and its molarity calculated. A sample of the NaOH solution will be titrated against the unknown HCl solution to calculated the volume needed to neutralize it. With these volumes the unknown molarity can be calculated. Theory: Solutions are made up of solvents and solutes. Materials known as acids when dissolved

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

Abstract here) GMOs Causing More Harm than Good A statement was issued by the U.S. Food and Drug Administration in the early 1990’s that advised consumers that there had been no danger associated with consuming foods containing Genetically Modified Organisms (GMOs) therefore no “safety” studies were necessary. The FDA furthermore made the ruling that the labeling of GMO foods was not mandatory in the year 2000. In 1992 a lawsuit against the BIOTECH community released 44‚000 secret internal memos into

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

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
