Procedure:
W followed Lab safety procedure by wearing the proper “PPE”. Module 6 analysis based on the concept of the titrant (known concentration solution) will add to the known quantity of analyte (unknown concentration solution) until the reaction is complete (method 8202).
We selected a volume of (100) ml for both of the sample and the duplicate, the volume of the unknown concentration solution is decided, by going back to the Range-specific information table (page IV) and locating our sample volume (see highlighted fields), we picked the titration cartridge with a concentration of (1.600) and multiplier number (1.0), now we are ready to conduct the analysis.

- We Draw about (110) ml of the unknown solution from the churn splitter (avoid

- Since the meter calibrated for pH and conductivity before, we repeated the above steps on the duplicate, we wrote down the reading in the lab data sheet. We were ready for the titration analysis according to (method 8202).

- First, we set up the titration apparatus, by setting up the Ring stand with universal clamp, we placed the magnetic stirrer on the ring stand and plugged in, followed by placing the magnetic stir bar into the Erlenmeyer flask.

- We sidled the sodium Hydroxide titration cartridge (1.600 ± 0.008 N) into the HACH digital titrator and slightly turned to lock the cartridge, followed by recapping the titration cartridge and inserting the delivery tube (G tube) into the digital titrator.
- We engaged the titrator piston into the titration cartridge by releasing the plunger button and turned the delivery knob slowly until the air was expelled (air bleeding process) then followed by resetting the digital counter back to zero and we cleaned the tip by using Kim

    The purpose of this experiment is to determine the pH of known substances by use of a pH color indicator of red cabbage and the use of a pH meter. As well as, to observe the pH changes in a substance by adding in more basic of acidic to buffered solutions and unbuffered solutions. This experiment will also will show how to calculate H3O+, OH- and pH by use of known values. In order to do this lab, there are a few key components one needs to know and understand first.…

    There are many instances in today’s society and on this planet, where it is crucial to figure out the unknown concentration of a known substance. The process that is used to figure out the unknown concentration of a substance is the process known as titration. Titrations are used in a wide range of work environments including forensic labs, and pharmaceuticals. A way in which titrations could aide society could start in a forensic lab. It could be used when trying to figure out the concentration of a drug or poison that may have been used in a crime.…

    SAMPLE PREPARATION: Wilcox shale and Pottsville shale samples are tested with the indentation method in this experiment. Both samples are quartz rich and silty shales which contain about 45 to 50% of quartz, 40 to 45% of clays and about 5% of plagioclase. Wilcox shale sample is from Louisiana and formed in upper Cretaceous while Pottsville shale samples are from Alabama and formed in upper Pennsylvanian. These two type of shale rocks are chosen because they are “local” rocks which was abundant and available in the lab, also they have very similar mineralogical compositions.…

    Skill #28 Kirstin Krueger #21839116 ELISA is an abbreviation for "enzyme-linked immunosorbent assay." An ELISA test uses different parts of the immune system, different antibodies, and color changes to detect immune responses in the body. CPLi, or Canine Pancreatic Lipase Immunoreactivity, is a specific lipase that is only found in canine pancreatic tissues. The CPLi ELISA snap test is made by Idexx and is used to measure the concentrations of pancreatic lipase in the serum of the patient. An antibody elsa test works when a blood sample and the conjugate specific for that test are combined together.…

    The study we chose to be looking at is the data set for American beers. Our main focus of the data set will be studying what affects the total amount of calories in a beer. A calorie is simply a unit of heat energy that fuels our body. The variables in our data set are the percentage of alcohol and the amount of carbohydrates in each beer. The goal of this analysis is to predict how the amount of carbohydrates and the total percentage of alcohol would result in a higher or lower caloric amount based on the variables.…

    Biological macromolecules are large molecules made up of smaller organic molecules. There are four classes of bio macromolecules : Carbohydrates, proteins, lipids, and nucleic acid. For carbohydrates and proteins these smaller molecules are known as monomers. These similar or identical monomers are covalently bonded together to create a large polymer molecule. Monomers, or base units are bonded together to create larger molecules via dehydration.…

    Experiment 1: Standardisation of approximately 0.25 M Hydrochloric Acid Abstract The aim of the study was to standardise a solution of hydrochloric acid with an approximate concentration of 2.5 M against sodium carbonate solution. The main steps of this experiment were preparing the sodium carbonate solution, transferring the solution into a conical flask by using a pipette, adding the bromophenol blue indicator and titrating with hydrochloric acid until the first green colour appeared. The concentration of hydrochloric acid was found to be 0.2508 mol L-1. Introduction Standardisation is a process which is carried out to determine the actual molarity of a solution.…
