Lab Report Proper Laboratory Technique - 2018 Words

In this lab, proper laboratory technique was implemented to have the experience in the lab. Furthermore, the unknown solution needed to be investigated, to determine the solution’s macromolecules. Three methods were comprised to determine the unknown, but a set of other solution was used to help as indicators to match the unknown solution’s results. It’s consisted of biuret, iodine and benedict solution. Iodine solution is used to determine if the source had starch or glycogen. If the source had glycogen consisted inside, there would be a reddish-brown precipitation occurring (Daniel Luzon Morris,1946). Iodine can also react with the starch, which could potentially create a The colour of the precipitate that forms a purple precipitate (J.M Bailey,W.J Whelan, 1960). The colour happens because of the iodine reacting with the glucose inside the starch. (J.M Bailey,W.J Whelan, 1960). Biuret test is to detect protein is extremely small, it is supposedly around the value of 0.5mg/ml. (Crowe,2014). This means 0.5x M of protein, the biuret solution would not change the if any solutions consisted less than the face value will not be detected 0.5x. When protein is detected, the solution would turn purple (Banks, 2016). Benedict solution is another method used to determine the unknown and if the solution The benedict solution is sensitive to the sugar and is able to detect and produce a shade of yellow, green or red (Stanley Benedict,1909). The colour represents that there isShow MoreRelatedAcademic Writing Is An Analysis Of Specific Academic Subject1372 Words   |  6 Pageswell written academic writing assignment consists of a structure that includes an introduction, body, conclusion, and reference section. Laboratory reports cannot be successful without the presence of writing. Laboratory reports are crucial to the field of Science and therefore need to be concret e and concise with the use of academic writing. Laboratory reports have a vital role in the field of Science.

For many students, labs are where their enthusiasm and interest in the material is stimulated. However, if the experiments appear unconnected to the theory learned in class, or unrelated to everyday life or the student’s major, they can be viewed as busy work: come to class, followRead MoreThe Laboratory Practices And Safety Precautions849 Words   |  4 PagesThe laboratory practices and safety precautions that were demonstrated in the video will help reduce hazards, due to, these videos gave precise guideline, that, if, adhered to will keep all, safe. some of these advisements were, but, are not limited to, the proper handwashing technique, (thoroughly washing under warmest water, tolerated, for twenty seconds), disinfection of work area before and after working, allowing for only the lab manual/book to be on area along with experiment and equipmentRead MoreSpring Syllabus2332 Words   |  10 Pages[pic] [pic] Florida AM University Department of Chemistry CHM 1045 Lab Syllabus | COURSE SYLLABUS | |Course Number: CHM 1045L |Course Title: General Chemistry I Laboratory | |Prerequisite(s): Read MoreComputer Forensics Mission : A Private Company1467 Words   |  6 PagesXYZ Inc. are subject differ from the laws governing law enforcement agencies.
