A Comparison of Gravimetric Analysis and Volumetric Analysis To analysis the proportion of an element in a certain substance‚ the experiment could be done by gravimetric analysis and volumetric analysis‚ and these two methods of analysing could be occupied on several different purpose of experiments as well. In a specific experimental condition‚ there will be one method that is the most suitable to choose‚ and it is depending on the temperature‚ substance status‚ pressure and chemical properties

GRAVIMETRIC ANALYSIS OF A CHLORIDE SALT (2013) Report By: ____________ Lab Partner: ___________ Group: CHEM 1001 Tuesday AM‚ Group H Purpose: This lab was conducted in order to determine the content of chloride in an unknown salt‚ using gravimetric analysis. Theory: The salt chloride content is easy to find because it is slightly soluble‚ making it possible to turn it into a precipitate. A precipitate reaction can be done using silver

GRAVIMETRIC DETERMINATION OF MOISTURE IN FERTILIZER SAMPLES J.P. FERRERIA DEPARTMENT OF COMPUTER SCIENCE‚ COLLEGE OF ENGINEERING DATE PERFORMED: DECEMBER 6‚ 2012 ------------------------------------------------- RESULTS AND DISCUSSION In this experiment‚ we demonstrated the process called gravimetric analysis‚ where we‚ specifically‚ measured the amount of moisture in a fertilizer sample. Here‚ the weights of the crucibles with the fertilizer samples are measured before and after placing

Abstract: Given the exuberant number of rape and sexual assault cases and the increased media coverage‚ it’s important to be able to distinguish between suspects. Can RFLP analysis differentiate between people‚ specifically in cases of sexual assault and rape on college campuses? To determine this‚ RFLP analysis performed using students in a BIOL 3600 laboratory. Buccal cells were extracted from the BIOL 3600 students‚ later purified‚ and then cut with two restriction endonucleases‚ MseI and RsaI

An Experiment on Soil Analysis Jacob Pitcher and Derrick Gillespie Chemistry Lab 112 Section 02 4/02/2013 Abstract A sample of soil was tested for possible contaminants and other information using a variety of techniques including moisture analysis‚ pH measurement‚ acid-base titration‚ chloride-ion electrode analysis‚ and flame testing. The sample had a greater concentration of chloride ions‚ no measurable CaCo3 ‚ and lower than standard moisture content. It was contaminated with KCl and

After watching the Milgram experiment and the abuse that occur in Abu Ghraib prison. It is clear that leadership roles and authority position can both influence people to do thing that are harmful and bad to others. Leadership focuses on gaining people to follow them and is more based on free will. While authority has the power to tell people what to do. In the Milgram experiment many people back up why they continue administering shocks by stating‚ “Because an authority figure was telling them

their behaviour did and it was nothing to do with individual personality. The experiment links into the Milgram experiment‚ in which ordinary people followed orders to give what they thought was electric shocks to people they could not see. Participants’ behaviour was slightly affected due to the fact that they were watched as opposed to a lurking variable (Hawthorne effect). This questions the reliability of the experiment and its findings to a certain extent‚ as we do not know how the participants

Once the solid was large enough‚ it could be washed‚ filtered‚ and weighed. The percentage of chloride present was found to be 24.73695223 (±0.00000006) %. Introduction The purpose of this lab was to determine the percentage of chloride in an unknown soluble salt sample through a gravimetric method known as precipitation gravimetry. The objective

Regulatory bodies worldwide set limits in order to control the amount oil and grease entering thewater reservoirs or the sea through industrial discharges and also limit the amount present in drinking water. The partition – gravimetric method involves extraction of dissolved or emulsified oiland grease from water
