Titration

They found from the titration of the wastewater that the olive oil soap will be the least harmful substance to use due to the fact that it only needed 99 drops of HCl whereas the rest needed significantly more drops. The simplicity of neutralizing the olive oil soap makes it…

The elution that corresponds to the alpha-ketoglutarate will be separated from the rest of the biomass. Once the alpha-ketoglutarate is isolated, it can undergo an acid-base titration in order to determine its concentration. An auto-titration will be in order to get the most accurate midpoint. The necessary calculations and data analysis will be done to determine the final concentration present in the biomass. This can then be compared for all of the groups:…

concentration must be determined by analysis or experimentation of the solution itself, as presented in ChemWiki. The purpose of titrating KHP with NaOH was to neutralize our experiment, or reach an endpoint as indicated by the phenolphthalein. Titration is used in order to find the concentration of a basic solution. The amount of reactants that have been mixed at the equivalence point depends on the stoichiometry of the reaction. In order to calculate the molarity of NaOH, My partner and I,…

by centrifuge, and then by decanting. Using filtration, we got measured concentrations of 0.017 M using the pH probe and 0.019 using titration. Using separation by centrifuge, we got measured concentrations of 0.024 M using the pH probe and 0.026 using titration. Using decanting, we got a wide range 0.017-0.026 M using the pH probe and 0.020-0.028 M using titration. This wide range on the decanting method suggests that this method is very inconsistent and is less precise than the other methods.…

For both trials, we used 25ml of Sprite. In Trial 1, 5.3ml of sodium hydroxide was added to the solution via titration. In Trial 2, 5.2ml of sodium hydroxide was used. To calculate molarity for Trial 1, we used the molarity of sodium hydroxide (NaOH), .101 and multiplied this number by the milliliters of NaOH used, 5.3. Then we used the molar relationship from the…

The learning objective of the experiment performed was to determine the pH of solutions that were given by using litmus paper and pH machine. The Experiment was kind of successful except for an issue with one of the solutions. When we tried to figure out the pH by looking at the litmus paper; we were stuck between a pH of 6 and 7. The best choice was to choose a number in between 6 and 7. Based on the two methods used to find the pH the results were close to each other. In this experiment…

This experiment analyzed the dissolved ions in a certain sample of seawater that was collected all around Galveston Bay and allowed an understanding of the composition of saltwater. The students were separated into four groups, each received a sample of seawater from a different location, such as Buoy 21, Day Mark 1, Pelican Island Cut, and the Coast Guard Station. The main ingredient in saltwater is water. Water is composed of two hydrogen atoms and one oxygen atom that are covalently bonded…

In Chemistry 2017-2018 I learned many things that can help out in daily life to keep others safe and to improve things. One thing that can be useful is knowing basic chemicals and elements to be safe and know what is inside things you have in everyday life. Knowing chemicals is good to know not to mix certain things that can possibly be dangerous or hazardous to your-self or others. Knowing not to mix ammonia and bleach is good because when mixed causes an toxic gas that can harm you, others,…

James Apostolico November 6, 2014 The Chemistry of Natural Waters Chemistry 111 Section: 005 Kareem Ali, Dima Alfawaz Stephanie Le Clair Introduction Water hardness is a way of defining the quality of water based upon the amount of Ca2+ and Mg2+ions that the sample contains.1 Water mostly becomes hard by flowing over weathering rocks which release these ions into the water. These released ions dissolve in water and then react with various elements, ions and compounds that…

Chemistry EE Concentration of Vitamin C in Kale Word Count: IB Number: 002811-00 Introduction Research question: How do different methods of cooking, namely steaming, baking, and frying, affect the amount of ascorbic acid in Kale? In a daily diet, arguably the most important thing to get a proper amount of is vitamins. Vitamins provide countless services and roles in the human body including helping with your immune system, repairing skin and bone tissues, and converting what you eat into…
