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

performed this test‚ the initially slant for unknown microorganism #17 is important. For this lab‚ two identical slants are used for two reasons. Firstly‚ the slant can be used to make sure that there is no contamination from the Nutrient Agar plate. Secondly‚ the second slant will become a stock culture to prevent the shortage of slants during performing the series of tests. Kliger’s Iron Agar tests can be used to determine multiple characteristics of unknown microorganism #17. Kliger’s Iron Agar slants

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

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

The poem I have chosen for this essay is "The Unknown Citizen". I felt the time period reflected W.H.

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)
